The laboratory assistant takes place in 1916 Russia and follows the story of Mariya doing her best to support her sisters and ill mother.
Although the premises of the story is interesting; the story dragged at times and the some of the dialogue felt out of place.
Thank you to Natalia Loya for providing this audiobook for review via NetGalley. All opinions are my own.

🥼🖤 The Laboratory Assistant ALC Review 🖤🥼


⭐⭐⭐⭐💫

🌶️


📗 The Laboratory Assistant is a lush, atmospheric, morally messy debut that works best when it embraces the collision of its various worlds: science and superstition, reason and madness, love and obsession, privilege and poverty, personal survival and political revolution.


Set in Petrograd in 1916, the story follows Mariya Sokolova, a young woman from a once-aristocratic family that has fallen into poverty. With her mother ill and her younger sisters depending on her, she takes a position working for Dr. Nikolas Rodin, a brilliant but troubled scientist attempting to find a cure for tuberculosis. Meanwhile, Russia is approaching revolution, and the increasingly unstable world outside the laboratory begins to mirror what is happening inside it.


What makes the novel particularly compelling is that the laboratory becomes almost a character itself. It is simultaneously a workplace, refuge, place of discovery, source of danger, and symbolic representation of Nikolas's mind.


The scientific experiments are fascinating (and, at times, morally questionable) because the book isn't simply asking, Can science save people? It's asking a much uglier question:

What are you willing to sacrifice to save someone you love?


That question gives the romance, the scientific plot, and the historical setting a common thematic center.


As much as I loved it, the novel isn't quite flawless. There are places where the plotting or transitions could have benefited from another editing pass. The middle slowed down or that certain plot threads weren't developed as fully as they could have been. Others, however, found the pacing compelling and praised the increasingly tense final act


So for me, this is a strong, highly atmospheric debut with a couple minor execution issues, but one whose ambition makes it considerably more interesting than a perfectly polished but conventional historical romance.


📓 Synopsis 


Petrograd, 1916. When recently impoverished aristocrat Mariya Sokolova takes a job assisting an enigmatic scientist researching a cure for tuberculosis, she expects a paycheck — not obsession, dangerous experiments, and an attraction to a brilliant man whose mind may be as unstable as his methods. As revolution rages outside the laboratory walls, Mariya must decide how far she's willing to go for family, love, and scientific progress.


Thank you to Natalia Loya and @netgalley for the opportunity to listen to this ALC. All thoughts and opinions expressed are my own and freely given.


🫵🏼 The Laboratory Assistant is perfect for readers who enjoy:

🧪 Mad-scientist / dangerous-genius characters

🕯️ Atmospheric Gothic fiction

❤️‍🔥 Slow-burn, morally complicated romance

🩸 Dark romance with horror elements

🏛️ Historical fiction set outside the usual Regency/Victorian England

🇷🇺 Russian history and revolutionary settings

🔬 Historical STEM/science

👭 Strong sister/family relationships

🧠 Stories exploring the intersection of genius, obsession, morality, and madness

🌹 Beautiful-but-creepy aesthetics — gaslit laboratories, secrets, old-world romance, illness, and danger


historical romance + Gothic horror + scientific experimentation + family survival story. Reviews particularly highlight the atmosphere, the Sokolov sisters, the slow-burn romance, and the tension surrounding Rodin's experiments.


Literary Equation 


Crimson Peak + Mexican Gothic + The Death of Jane Lawrence + The Great Gatsby's fallen aristocracy + a mad-scientist Gothic romance


Or


Russian Revolution + forbidden attraction + tuberculosis + a morally questionable scientist + a gaslit laboratory + fallen aristocracy + “how far would you go to save the people you love?”



⚠️ TW/CW: SA, poverty, starvation, illness, blood, 🔫, 💀 bodies, implied grape, kidnapping, drugging, experiments done without consent, vomit, scenes inside a mental hospital 


❓QOTD: If a loved one was facing a long, painful death (no chance of survival) and you had access to a promising experimental treatment that hasn't had adequate human trials, would you give the treatment to your loved one (who can't communicate with you), or no? 


❗AOTD: That would be such an agonizing choice. I think I would give it to them, and hope that the worst case is it providing a data point to help other people in the future. 



📖 Plot 4.5


The premise is excellent. The plot is imaginative and ambitious, and the overall trajectory works. The execution isn't always as seamless as the premise deserves.


A fallen aristocrat becomes the assistant to an obsessive scientist researching tuberculosis while Petrograd is simultaneously being torn apart by revolution. That gives Loya three pressure cookers operating simultaneously:

Mariya's family's desperate financial situation

Nikolas's increasingly dangerous scientific obsession, and Russia's political collapse. And they increasingly collide, and the lead up creates a constant undercurrent of tension. 


The strongest aspect of the plotting is how personal and historical stakes reinforce one another. Mariya isn't interested in revolution because she's trying to feed her family. Nikolas isn't interested in politics because he's consumed with his research. Yet neither of them can escape the rapidly changing world around them.


The final portion becomes particularly intense, with the scientific and moral questions escalating dramatically. The way the climax brings the various tensions together was, for me, immaculate in its execution. 


It's in the final portion that leaves me torn about how to rate, and more importantly, how to feel about this book. Nikolas abducts a rapist and uses him for medical experiments. Which, in fiction at least, I'm on board with as this person is unquestionably guilty of rape - multiple rapes, if I recall correctly. Nikolas is unquestionably morally grey already, so him doing this wasn't out of character. What I'm torn about is the other characters indirectly blaming it on his unnamed mental illness. As I recall, they don't outright verbalize that, but it's heavily implied. 


On one hand, that's likely historically accurate as to what people likely would've said about something like that back then (probably, idk, I'm far from a historian). Mental health still has stigma attached to it today, but it was much more drastic and accepted by the public back in 1916. I just don't love Nikolas's decision to abduct a horrible person and use them to advance his tuberculosis treatment being blamed on his mental health. 



➕ Loved 

• The unusual combination of Russian Revolution + gothic + romance + science

• The continually escalating stakes

• The suspense and morality surrounding Nikolas's research

• The increasingly morally questionable choices 

• The climax 🫣

• Multiple seemingly separate threads gradually converging. 

• The mix of historical fiction, romance, gothic (almost) horror, psychology, and mystery 


➖ Didn't Love 

• Slight loss of momentum in the middle 

• Some transitions are a bit sudden, not as refined as I'd have liked



📜 Themes & Deeper Meaning 4.5

This is one of my favorite aspects - the way it made me really ponder my morals. There's considerably more going on beneath the surface than the synopsis initially suggests.


A big thematic question is: how far love can, or should, go. Mariya's entire existence is organized around caring for other people. She sacrifices for her mother and sisters, and that makes her relationship with Nikolas particularly interesting because eventually the question becomes whether love can transform from care into enabling.


Nikolas represents another version of devotion: obsession disguised as love. His scientific pursuit of a tuberculosis cure is admirable because people are dying. But the book increasingly asks whether the noble goal of saving lives can justify increasingly unethical methods. And whether potentially saving many in the future is worth a few lives now. That creates a fascinating moral equation:

Love + desperation + power + obsession = the possibility of monstrous choices.


The laboratory itself functions beautifully as a metaphor. It's a place where things are taken apart, manipulated, transformed, and reconstructed. And that's essentially what is happening to the characters emotionally.


The Russian Revolution provides another excellent thematic parallel. The society outside is breaking apart while the characters' personal worlds are breaking apart inside.


Other major themes:


Love vs Obsession — when does devotion stop being selfless?


Science vs Morality — does discovering something that could save thousands justify unethical experimentation?


Class and survival —

Mariya's aristocratic background doesn't protect her once her family loses its money. The novel demonstrates how quickly social status becomes meaningless when you can't afford food or medicine.


Women and intellectual autonomy — 

Mariya and Sofia are both intelligent women trying to exercise agency in a society that limits their options. Their intelligence isn't simply treated as a novelty, nor is it mocked or questioned by the male characters.


Madness vs. Genius

This was the most complicated theme for me. 

The novel clearly wants to explore the historical association between brilliance and madness, but it occasionally tows the line into equating mental illness with dangerous or immoral behavior. 


➕ Loved 

• Strong thematic layering

• Excellent parallels between political upheaval and personal upheaval

• Questions about morality don't have easy answers

• The science/love/obsession connection is fascinating

• Leaves some room for interpretation

• Leaves the reader plenty of morality questions to ponder 


➖ Didn't Love 

• The mental-illness/madness theme feels potentially controversial in its execution (I'm still torn on it and I thought about it for almost 24hrs)



🎧 Narration 4.75


Narrated by: Natalia Loya (author narrated)


Loya gives us clear storytelling with a literary delivery rather than an elaborate full-cast/character-performance approach. While we don't get vastly different voices for characters,  they are differentiated via things like inflections. It worked well enough for me, it suited this book quite well. The prose is atmospheric and literary, and a measured delivery allows the gothic mood to develop. The historical setting and psychological unease benefit from a narration that doesn't rush.


I could be reading more into it than what's there, but I don't think I am. The audiobook starts off with a tone that's almost hesitant, almost unsure, or just shy or lacking full confidence. As the story goes on and Mariya grows, that slowly morphs into a confident tone - one not afraid to take up space. Maybe it's just the author/narrator growing in their own confidence, becoming more sure in their narrative skills. Either way, it works very well for this story and these characters. 


A good fit if you like author-narrated literary fiction and atmospheric delivery; less ideal if you want a highly theatrical, character-actor-heavy audiobook.


➕ Loved

• Loya's intimate understanding of the material

• Clear familiarity with the characters and story

• Clearly spoken & well enunciated narration 

• A measured, literary delivery

• The fact that the person narrating understands exactly what emotional beats she intended when writing them.

• The atmosphere translates naturally into audio.


 ➖ Didn't Love 

• The prose's tendency to switch between character names and descriptors slowed my listen a little


💫 While it doesn't have the polish or theatrical range one might expect from a veteran audiobook narrator, I personally didn't feel like that impacted my experience or enjoyment of the story. 



✍🏼 Prose & Dialogue 4

Loya's prose is often lush, highly atmospheric, evocative, rich in sensory details, and, at times, vigorous. All while staying accessible, easy to read and follow. 

 

The main thing I didn't love with the prose may have, at least in part, been exacerbated by me listening to it (rather than reading with my eyes) and having a hearing impairment. The character label issue. Switching between various character descriptors, "the fallen aristocrat," and their names, "Mariya," was a bit of a struggle for my brain to keep up. Maybe had I been reading with my eyes, it wouldn't have been an issue for me. But I wasn't. Anyway, doing that can be atmospheric once or twice. When it happens repeatedly, especially with multiple characters present, it became confusing for me and pulled me out a couple times.


Some transitions between paragraphs could use refinement. Large gaps of time between paragraphs, for example. 


➕ Loved

• Beautiful imagery

• Strong sensory descriptions

• Atmospheric language

• A literary, old-world quality

• Some genuinely gorgeous passages


➖ Didn't Love 

• Overuse of character descriptors

• Occasional clunky transitions

• Occasional ambiguity about who is speaking or being described



⏳Pacing 4

What we get is a mostly effective slow-burn structure with a strong escalation.


The story steadily accumulates tension rather than relying on constant action. The laboratory, Nikolas's behavior, Mariya's family problems, the tuberculosis crisis, and the revolution create an increasing sense that something terrible is approaching. The final act is considerably more intense than the opening. It moves along at a quicker pace (without feeling rushed). 


That said, the middle isn't perfectly even. The beginning and end flowed and moved well, but small bits of the middle didn't quite have the same momentum. The bulk of the book I didn't want to put down (well, press stop or pause), though. 


➕ Loved

• Strong buildup

• Suspense increases gradually

• Final act is gripping

• Enough mystery to keep turning pages


➖ Didn't Love 

• Some slower middle sections

• Abrupt time/scene transitions

• A few threads feel temporarily disconnected.



🗺️ Gothic Atmosphere 5

The vivid gothic elements also aren't merely decorative. They reinforce the novel's central ideas about death, illness, obsession, and moral corruption.


The atmosphere is fantastic, the laboratory, the illness, the tension in the city, the gaslight, the mausoleums and crypts, the sanatorium visits, the medical experiments, the sense that something is deeply wrong with Nikolas, the possibility that what we're witnessing may be science, "madness," or something stranger.


It all creates that delicious gothic uncertainty of: 'I don't know what's happening, but I absolutely do not want to go down into that basement.'


 ➕ Loved 

• Extremely strong sense of place

• Dark academia-esque laboratory setting

• Macabre imagery

• Psychological unease

• Gothic medical/scientific atmosphere

• Excellent use of historical instability to amplify dread.



👥 Character Development 4.5

We get well developed characters, full of depth, dimension, and some more morally grey than others. 


Mariya is the heart of the novel. Her development is particularly effective because she begins from a place of necessity rather than ambition. She's not initially trying to become a scientist or revolutionize medicine.

She's trying to keep her family alive. That makes her later involvement in Nikolas's work meaningful because her motivations gradually expand beyond survival. She's resilient, intelligent, and empathetic. Her sisters also contribute significantly to the emotional architecture of the story. The Sokolova family isn't just background scenery. Their financial desperation makes the stakes tangible.


Nikolas - I waivered on him multiple times, but I think that's likely intentional. He's fascinating precisely because he's difficult to categorize as either romantic hero or villain. Initially, Dr Rodin seems mercurial, a moody genius. As time goes on, his mental state slowly morphs into more of a Jekyll and Hyde type situation. The specific cause of his malady isn't named, and while I'm incredibly curious about what it was, and I'm kind of glad it isn't. Leaves it open to the reader to wonder about. I love that Mariya doesn't just ignore or excuse everything just because he's good looking. Even though both their feelings are genuine, that doesn't make his actions ok - and Loya makes that a deliberate point. 


➕ Loved

• Mariya is easy to root for

• Strong female characters

• Family relationships feel important

• Nikolas is fascinatingly complicated

• Sofia provides another strong female perspective

• Characters have meaningful moral conflicts


➖ Didn't Love 

• Nikolas's characterization can become too closely tied to his mental illness

• I would've loved more development in particular relationships



🖤 Romance 4

We get a strong romance taking place in a dark, morally complicated historical time. The romance is slow-burn, morally complicated, and atmospheric rather than fluffy. Mariya and Nikolas are compelling because their relationship grows out of proximity, intellectual respect, vulnerability, and mutual dependence. The chemistry is intense. Nikolas's instability complicates the relationship considerably and I quite enjoyed how that was handled overall. 


It ends up becoming a question of if Mariya loves Rodin, the man, or is she emotionally dependent on the version of Rodin she believes she can save? 


The romance started sooner than I'd have liked and progressed quicker than I need to fully buy into their love. 


➕ Loved

• Excellent tension

• Forbidden/complicated dynamic

• Intellectual attraction

• Slow-burn qualities

• Romance is intertwined with the larger plot

• Strong chemistry


➖ Didn't Love 

• The progression wasn't quite convincing enough

• Romance developed more quickly than I wanted

• Not quite enough on-page progression to make the emotional transition completely convincing



🌶️ Spice 4

The book is sensual and romantic. There is explicit content, but the emphasis is much more on tension, desire, forbidden attraction, and emotional intimacy than on extended or numerous explicit scenes. The only reason this aspect isn't a 5 is because I would've preferred a slower progression, to see their emotional connection grow on page before any steamy scenes.

Set in the early 1900s in Petrograd, this gothic novel follows Mariya and her family in the quest to stay alive in this war torn area. 

Mariya's family was aristocratic due to her father's position in the army. However, once he dies, life becomes much harder for them, and Mariya is trying to support them the best she can. Her mother has consumption (tuberculosis) and isn't able to work, so it falls on her to support the family. She has two younger sisters. One is in secretarial school, and the other is young and in school. Mariya is lucky and is able to land a position with a doctor that can't seem to keep assistants. The truth is unraveled, but never full explained. Along the way, she falls in love with the doctor, and overlooks his foibles despite the impact that they have on her. 

This novel was intriguing, and I found myself concerned for the family. They were living a meager existence in Petrograd, and this was about the time of the rise of the Bolsheviks and the Russian Revolution. While the focus on this aspect was minor, it was something the characters had to be concerned about for their safety and wellbeing.

This novel addresses mental health, and the search for a cure for consumption. Not a lot was known about this illness, and they thought it was hereditary. Dr. Nikolas Rodin lost a fiancée to this disease and was on a quest to discover a cure. Did he? Or did he discover something that was a temporary measure?   

I was engaged with this novel, but do feel like some of my questions were not answered. There are a few spicier scenes that bring together Mariya and Nikolas, but I felt like their romance was a minor part of the overall story. Sofia, Mariya's sister, is torn between getting involved with the revolution and helping her family. I did like Viktor's character. He was Nikolas' lifelong friend, and he owed a lot to him, but was he helping or hurting the situation?

I also thought it odd that at times, the characters were not called by their name, but by the jobs - the assistant, the psychiatrist, etc. This threw me off at times since the flow of the paragraphs was interrupted.

It was an intriguing book, and we give it 3 1/2 paws up. It would be good for anyone who enjoys gothic novels with a side of romance and a tiny bit of horror.

The following is an abridged version of my review. The full length version can be found on my site www.readinghasruinedmylife.com

Thank you to Apprentice House Press for sending me an advanced copy of The Laboratory Assistant by Natalia Loya. They aren't paying me for my review, they just sent me the book for free; all thoughts and opinions are my own.

A quick content and trigger warning. The Laboratory Assistant is set in the 1910s and has scenes set in a mental hospital. Mental hospitals from history are notoriously bad and patients were not treated kindly in them. While the book does not go into detail about mental health treatments or the horrors of the mental hospitals at the time, I feel it is only right to mention this topic is briefly featured in The Laboratory Assistant. It should also be noted that rape and sexual assault are mentioned in the novel as well and play quite a large role at the end of the story.

First and foremost, I must applaud Natalia Loya for her beautiful prose and imagery. The dank basement laboratory was chilling, the few finer possessions of Mariya’s were stunning, and the pains of hunger and general unease of Petrogard were strongly felt. There are certainly strong passages in this novel. That being said, there are passages in The Laboratory Assistant that do not feel as developed as others. The imagery isn’t always there. Some transitions could have been written better. There are a few that are clunky and don’t flow smoothly. One chapter will end and suddenly it’s a month later and I don’t know exactly how I got to the next scene.

Now, I have a major fault with this book. I greatly enjoyed it up until the final third. I was invested. And then Nikolas kidnaps a rapist and begins using him as an unwilling test subject for his consumption cure. I am still on board with this. Nikolas has entered a morally gray area, and that is fine, the Book Girlies will gladly look the other way when it comes to Nikolas kidnapping a horrible human being. But, the characters closest to Nikolas all but explicitly say “he’s done this because he’s mad.” Nikolas has an undisclosed mental illness and it feels like his mental illness is being villainized.

I am fine with Nikolas being morally gray. Morally gray villains are my favorite. I am fine with him kidnapping a rapist and doing what he does. The moment another character says Nikolas has done this due to his mental illness is where I draw the line. The decision Nikolas comes to regarding the kidnapping is one he would have made regardless of his mental health. I do not like that the other characters correlating his bad actions with mental illness. Yes, The Laboratory Assistant is set in 1916. Yes, there was a strong stigma surrounding mental health at the time. But those facts do not negate the fact that Nikolas’s mental illness is being villainized. It just doesn’t sit right with me and made me dislike the otherwise enjoyable read. It left quite a sour taste in my mouth.

Thank you once again to Apprentice House Press for sending me a copy of this book. I greatly appreciate it every time someone out there wants to send me books.

ARC READ:
Mariya , recently dealing with poverty with her two sisters and Ill stricken mother after their father’s death trying to do anything to make ends meet.

The job with Nikolas Rodin proves to be fruitful with some challenges to an undisclosed condition that drives him mad. ( condition still unknown and really bothered me , was hoping it would have been disclosed what was actually wrong as his best friend was psychiatrist but potentially there wasn’t a name for it in 1916?)

Mayira pushes through all obstacles of sickness and heart ache as she starts falling for the scientist, despite his flaws she stands by his side.

This book was captivating and suspenseful in third person POV. Though at some points it was difficult to know which character was being spoke about.

Overall ⭐️⭐️⭐️⭐️

First of all, thank you to NetGalley, the publisher, and the author for providing and sharing this ARC.

Not only on NetGalley, but this is actually the very first book I’ve given 5 stars this year. I truly vibed with the atmosphere described in the story, and I have to say I am absolutely, absolutely in love with the writing style. I found myself enjoying the way the author told the story even more than focusing on the plot itself. The details, especially the foreshadowing, were well-placed and meaningful. While the overall message isn’t necessarily new, the way the author weaves in themes of disease, humanity at the threshold of scientific discovery, and the cracks in the feudal social structure was fascinating. I went from worrying about the sick to worrying about the revolution!

Although I emphasize how much I enjoyed the writing, that doesn’t mean the characters and plot didn’t engage me. As mentioned above, the plot was compelling. Regarding the characters, it’s been a long time since I felt such empathy for a female protagonist. She is kind, careful, and incredibly perceptive, with a clear and consistent moral compass that holds steady from beginning to end.

Overall, I really loved this book and the author. Considering it’s a debut novel, I would rate it quite highly.

That said, my positive reading experience doesn’t mean I didn’t notice a few small issues with word usage. Normally I might overlook them, but since this is categorized as historical fiction, I’d like to offer some feedback. A few scientific terms—particularly hormone names—were coined after 1920, with air embolism only being reported in the 192x period. Additionally, regarding formatting, the EPUB I received wasn’t divided into chapters; it was just one continuous section. I’m not sure if the publisher intends to release an ebook version, but if so, I hope the formatting will be revised.

[Thank you to NetGalley for an advanced listener copy in exchange for an honest review.]

I listened to the audio version narrated by the author, and at first I wasn’t sure about it. I’m so used to audiobook narrators being voice actors and this felt more like an older sister reading me a bedtime story. She grew on me, and I really imagined her voice as Maria, our main character. The plot started out slow but it also grew on me. I’ve never read anything set during the Russian Revolution and I enjoyed learning some of the history and doing additional research on my own. Earlier this year, I listened to Everything is Tuberculosis by John Green, so I found the consumption aspect of the book to be really interesting, especially from the perspective of searching for a cure. If this book wasn’t a “read now” option on NetGalley, I’m not sure I would’ve picked it up, but I ended up being glad that I did.

As someone who has a tendency to shy away from both historical fiction and gothic horror, I was shocked by how tightly “The Laboratory Assistant” had me in its clutches. I was expecting to find a slow buildup, a prolonged period of establishing timelines and characters, and perhaps a challenge for me personally to remain interested and engaged. Believe me when I tell you that was not the case. I was immediately enraptured in this story, quickly becoming a fan of Mariya and her strength, tenacity, and self-sufficiency.

Strong FMCs, women in STEM, political revolution, love, death, and perhaps a dash of insanity? What could you possibly love more?

I grabbed this as a Listen Now on NetGalley, and thank you SO much for the opportunity to hear this as an ALC.

The narration was clear, concise, and sweetly portrayed. It was so clearly done, I could speed it up to 1.25x speed with no loss of clarity.

The story was so good— I struggled to pause it when I was being distracted! I was enraptured by the mystery, the Bolshevik, the science, and the characters.

If Nocticadia had a love child with the Victorian Gothic/Russian Historic era, this is the product.

tw: sexual assault, poverty, starvation, illness, blood, guns, dead bodies, implied rape, kidnapping, drugging, experiments done without consent, vomit

A special thank you goes to Netgalley and Mindbuck Media for providing me with a copy of this book. Please know that this does not influence my rating or thoughts on the book itself.

I have some thoughts about this book. I think the problem was with the synopsis. It didn’t seem to match what the genre was. So this book was marketed as a romance and historical fiction. But the way the synopsis was written, it made it sound like it was going to lean more into horror. So I was a bit thrown when there was so much romance in it. But I suppose it might be my fault for not paying attention to the book's genre. Netgalley was pretty clear with its tags, but I guess I did not pay attention to that.

As for the book itself, I did enjoy it for the most part. I had a problem with the writing, though. Oftentimes, there were these weird descriptors that would happen in the middle of the paragraph. It’ll go from using their names, like Mariya and Rodin, and then it will switch to the dancer, the assistant, etc. It was jarring, and I got confused at times. Especially when Mariya was called the dancer, because we didn’t get to know Mariya when she was a dancer. We only got to know her after the fact.

I think my main problem with this book was that I was expecting it to go a lot darker than it did. I truly expected the doctor to go just insane, and I truly thought Mariya was going to go with him, kind of like a Joker and Harley Quinn thing. I know that is a horrible thing to compare, but it’s the first thing I thought of. But alas, Mariya only went just a little dark. And I think that is why I rated the book as low as I did.

Overall, I did enjoy the book, but I had a few issues with it. I don’t know if it was just me not reading the synopsis right or what, but I just felt like my expectations were not met. I wouldn’t be opposed to reading this author again, as I think they can write and write well, but overall, this book was just a bit of a miss for me.

Audiobook received from NetGalley in exchange for an honest review

🖋: Natalia Loya
🎧: Natalia Loya
⭐: 4.5

Lush with elegant prose, vivid descriptions, nuanced characters, The Laboratory Assistant stands out as an unforgettable debut. With a plot painted across a dreary, gothic canvas of Petrograd, 1916, poverty, war, revolution and tuberculosis threaten to swallow Imperial Russia whole.

Penniless aristocrat, Mariya Sakolova desperately struggles to support her younger sisters and consumption ridden mother. After finding employ as a laboratory assistant to an enigmatic young scientist, Dr Nikolas Rodin, Mariya steadily descends into a world of science, sickness, madness darkness and tantalising romance. In a race against time and the political instability, Mariya helps the tormented doctor search for a cure for the disease ravaging the streets and those close to home.

Each character was complex without being insufferable; their challenges felt bleak and innately human. They each shone in different ways, Viktor's unwavering loyalty, Nikolas's dedication (bordering obsession), Sofia's resilience, the youngest Sokolova sister's intuition and the lengths Mariya will go to save those whom she loves. However, I adored the manner in which character flaws are not romanticised or dismissed, rather they are extensively explored.

The question of morality is posed. What would you do to save someone you love? Luckily, I am a lover of dark romance and the poignant answer resonated with me: Everything. Absolutely loved the beautiful conclusion reached that even the mentally unwell deserve to be loved.

Honestly, the last 40% stressed me out, in the best of ways. While I may not be a historian nor Bolshevik expert, it is common knowledge how it all ended. Thus, with that in mind each event heightens the tension and claustrophobic atmosphere.

My critiques are almost insignificant. Nevertheless, while I have no major frustrations with the overall pacing it almost felt as if important moments relevant to the romantic progression occurred off page. Furthermore, I recognise that writing in the third person presents certain challenges to authors but the overuse of terms like "the scientist", "the psychiatrist" etc became tedious towards the middle of the novel. Paradoxically, the terms fitted in well in the beginning and end. Finally, it hurts me to say this, but the audio performance was mediocre at best. While characters can be identified by minor inflections of voice the story suffers by this performance.

In sum, this was a genre bending, unforgettable experience. A haunting gothic romance depicted against a society on the cusp of violent change that will leave you begging for more.

Natalia Loya’s The Laboratory Assistant is a compelling, deeply emotional and often tense story set in Petrograd in 1916, shortly before the Bolshevik Revolution. We follow Maria Sokolova, a twenty-year-old aristocrat left destitute with her widowed mother and sisters by her father’s failures. Desperate for money, she becomes assistant to the reclusive scientist Nikolas Rodin.

I especially appreciated Loya narrating the audiobook herself, drawing listeners into the precarious lives of Petrograd’s residents at the height of World War I, when many families lost the men, whose incomes sustained them. Harsh conditions also fuelled tuberculosis, a poorly understood disease that weakened and killed impoverished people across Europe. Loya makes both threats immediate as Maria and her family stretch a meagre income while their matriarch declines from grief and disease. Both the characters and the reader sense that one misstep could change everything. Although I admire Loya’s writing, waiting for their desperate situation to worsen was almost unbearable.

Maria is deeply loving and resilient. Once destined for a comfortable life as an officer’s wife, she loses that security through circumstances beyond her control. She does whatever it takes to keep her mother and sisters alive as each new hardship arises. At times, I desperately wanted her to stop and put herself first, even if only to sleep, because she rarely considers her own needs or desires. Nikolas enters her life first as her employer and later as her lover, but he never distracts her from her duty to her family. They always come first, which I believe explains Maria’s final choice. Without giving anything away, this is more than a survival story. The Laboratory Assistant is a historical Gothic novel whose darkest moments will haunt the reader.

I found myself repeating a mantra: ‘They’re doing this because otherwise things will be far worse for them, everyone you’ve grown to care about and thousands more.’ I suggest doing the same. Your stomach may turn a couple of times, but it also feels so good. No spoilers, though fellow readers and listeners will know what I mean.

Prepare for the darkness. This is no light read: it asks you to care for characters who do terrible things to survive and protect those they love. It immerses you in one of Russia’s bleakest periods and leaves you needing a comforting drink and a moment to escape the horrors of 1917, when people could lose loved ones on the battlefield and their homes at the same time, utterly powerless.

The Laboratory Assistant is a phenomenal read, and I’m glad I lost myself in its darkness for a while.

I received a digital copy of the book in exchange for an honest review.

The Laboratory Assistant is the debut novel by Natalia Loya. It is primarily a historical fiction with elements of romance and gothic horror.

The Sokolov sisters are the heart of this novel and they are why the story works so well. Much of the story is a tale about an everyday struggle for survival. Mariya runs the family while the eighteen year old Sofia attends secretary classes. Sofia’s involvement with the Bolsheviks caused complications for the family but she is fiercely protective of her sisters. By the start of the story they have both sacrificed their dowries in favour of food and basic supplies – and all to protect Darya, their eight year sister and the embodiment of innocence in the novel, from having to do the same.

One aspect of the story that I really liked was that Mariya and Sofia’s intelligence was never mocked or questioned by the male characters; quite the opposite. I’ve read several historical novels where one of the key plot points involves the female protagonist being forced to hide her intellect. While The Laboratory Assistant does highlight the difficulties facing this family with no living male relatives, Mariya and Sofia’s knowledge, learning and reasoning was always respected and encouraged by their peers.

The character of Dr Nikolas Rodin straddles the lines between anti-hero and villain. Both his desire and motivation behind wanting to find a cure for consumption comes from a good place but his methods become increasing dark as he moves onto human experimentation. The novel stresses both Rodin’s love for Mariya and his internal battle with mental illness as the reasons behind his ability to perform his ghoulish experiments without guilt. While for me it didn’t affect my enjoyment of the book, I do wonder how the story and Rodin’s relationships would have played out if Loya has chosen instead to make the character carry out his experiments in spite of his illness rather than because of it.

The Laboratory Assistant is filled with engaging characters, a slow-burn believable romance, a brooding gothic atmosphere and suitably macabre scenes during the climax. The pacing of the story was really good and the novel kept me wanting to read more.

Oh, dear. This book STRESSED ME OUT.

It’s been quite a while since I read a book and was constantly thinking “Oh, something bad didn’t happen for quite a while… Those characters will go through some kind of awful horror again very soon!” And I absolutely love books that make me feel that way. It's even better when they manage to lull you into a false sense of security before hitting you with something even worse. The Laboratory Assistant definitely succeeded in doing exactly that.

We start the book in an already dire situation, so from the very first pages you get the sense that she has almost no options left and is forced to seize whatever opportunities come her way.

For me it also always felt as is feeding her family and staying alive was the highest priority for her through the whole book and the reason she is motivated to commit certain acts she would not do is she was not with her back to a wall.
Her priorities also did not change with the introduction of the romance. Her feelings for Nikolas felt like a nice addition but not a distraction from her actual goal and I really enjoyed that.

I also really loved all the supporting characters who felt really nicely fleshed out and all with an actual purpose for this story.

One thing that did take me back for a bit was the very extensive use of synonyms to describe a character. Having a main character constantly being referred to as “the man” or “the assistant” when I usually encounter those type of descriptions for less relevant side characters felt a little bit off while reading. I found myself rechecking several times which characters were having and interaction right now.

Since I listened to this as an audiobook, I also want to mention the narration: Initially I was not a big fan because it often felt more like someone was just reading the book out loud instead of trying to bring some life into the story with their voice. However, once I realized that the author herself was doing the narrating, this immediately became more charming and gave it a whole different and personal feel. I really loved that.

Thanks to NetGalley for providing me with a review copy of this book.
Natalia Loya’s The Laboratory Assistant is an impressive debut that combines historical fiction, romance and psychological drama into a compelling narrative. Set against the turbulent backdrop of Petrograd in 1916, the novel unfolds at a moment when Russia stands on the precipice of revolution. The atmosphere of political unrest and social upheaval permeates every page, lending the story a sense of urgency and inevitability.
At the heart of the novel is Doctor Nikolas, a brilliant young physician whose obsessive dedication to finding a cure for consumption—one of the deadliest diseases of the era—drives much of the narrative. His scientific ambition is both admirable and troubling, revealing a man willing to sacrifice almost everything in pursuit of discovery. Into his world steps Mariya, a resourceful young woman struggling to support herself and her sisters in a society that offers few opportunities to women of limited means. When she begins working as Nikolas’s laboratory assistant, an unexpected bond develops between them, one built on mutual respect, intellectual curiosity, and growing affection.
What makes the novel particularly engaging is the complexity of its characters. Mariya is a resilient and sympathetic protagonist whose determination to carve out a place for herself in a rigidly stratified society makes her easy to root for. Nikolas, meanwhile, is far more complicated. His brilliance is inseparable from the mental struggles that haunt him, and Loya portrays his condition with nuance and sensitivity. As his psychological difficulties begin to interfere with both his research and his relationship with Mariya, the emotional stakes of the story deepen considerably.
The novel gathers momentum steadily before becoming especially gripping in its final chapters. The ending carried a tension and emotional intensity that I did not anticipate, keeping me fully invested until the last page. For a debut novel, the storytelling is remarkably assured. Loya not only crafts a tightly woven and absorbing plot but also offers a thoughtful portrait of a society deeply divided by class, privilege, and social expectations. Through the experiences of her characters, she captures the uncertainties of an era on the verge of profound transformation.
Honestly, The Laboratory Assistant exceeded my expectations. It is a richly atmospheric historical novel that balances personal drama with larger social and political themes, marking Natalia Loya as an author worth watching.

I would give this 3-3.5 stars. This was a pleasant surprise for me! My first historical dark romance set in Russia during the 1917 period, and I found the time period very interesting. I wasn’t too familiar with it beforehand, but I feel like I got a good introduction to it. I liked the setting, with the heroes being doctors and part of a university, and I especially enjoyed the family dynamics between the sisters.
I thought the romance was okay. It definitely had some wonderful moments and a few gaps in the story, but not too many, and the overall story was good enough to overlook them.
Around the 40–50% mark, the plot slowed down quite a bit, and the story started to feel a little dragged out. However, around the 68–70% mark, the plot picked up again and sparked my interest. I also really liked the conclusion!
One thing I found a little confusing was the inconsistency with the character names. For example, the heroine would sometimes call her mother by her first name and other times call her Mom. There were also characters like Maria/the assistant, Nicholas/the scientist, and Victor/ the psychiatrist, who seemed to be referred to by different names at different points in the story. Not all the characters had this issue, but it did get a little confusing at times.
As for the spice, this is definitely on the lower end, with only about 1–2 scenes, so keep that in mind if you're a spice girly!

The Audiobook: Thank you to NetGalley and the author, Natalia Loya, for providing me with an ALC of this audiobook in exchange for an honest review. I appreciate the opportunity to listen to this story narrated by the author. While I thought she did a decent job, I personally felt the narration could have benefited from a little more expressiveness and character differentiation to really bring the characters and their emotions to life. I think a more experienced narrator might have helped elevate the audiobook experience for me.

Review of advance reader copy received from NetGalley

A gothic historical novel set in Petrograd, Russia in 1916 where a young woman Mariya is barely making ends meet after her father dies and left a large debt during a time of political unrest. With her mother is sick in bed with tuberculosis and 2 younger sisters. She gets an opportunity and takes the job as an assistant for Dr. Nikolas Rodin, a reclusive but brilliant scientist, who seems to be conducting secret experiments. Is the generous pay offered too good to be true and is there something more sinister happening?
I was very intrigued by the premise. The setting was very unique and had a lot of potential. It was easy to read. The beginning definitely hooked me but did start to fall apart after about the first ⅓ of the book. It lost some of the more eerie gothic elements. By the synopsis, I did think it would be darker than it ended up. The writing kept distracting me for example within 2 pages it would say “the doctor", “the scientist”, “the young doctor”, “the man”, “Nikolas”, all of which would be referring to Nikolas and sometimes I had to read the passages multiple times to make sure if they were referring to the same person or if someone else was in the scene that I missed. I didn’t really find any of the characters likeable and felt the plot had too many threads that felt undeveloped and the main plot was fine but my expectations were very high and it didn’t match it. If you are looking to dip your toes in dark romance and don’t want something too dark and are intrigued by the setting and like historical fiction, this book may be more for you.

Set in Petrograd (St. Petersburg) right before the Russian Revolution, The Laboratory Assistant is a dark historical fiction novel that explores the compounding and competing interests of family, duty, loyalty, and love under exceptionally trying circumstances. We join the protagonist Mariya shortly after her life of privilege has drastically changed for the worst, and follow her across a series of outside events and personal choices that shape the future of her life and the lives of her loved ones. The volatile setting provides an appropriate background as a question is posed to the reader: how far would you go for those you love? And how much of yourself would you lose in the process?

Natalia Loya frames this overarching moral inquiry within a compelling and approachable framework, grasping your attention from the first chapter and holding it until the finale. Her elegant but accessible prose allows an immediate attachment to her characters and their plights, appreciating their layered humanity while progressing the narrative at a steady pace. The author has a peculiar talent for developing and propagating tension, in an unexpectedly but delightfully nonlinear fashion. There are a few particular scenes in the book with memorably acute emotional engagement (namely, the mental asylum and first descent into the laboratory basement), showcasing Loya's mastery of pace, finesse with word choice, and natural ability to express a distinct mood with balanced imagery.

The Laboratory Assistant is an excellent debut work by a promising new author. The book delivers both an engaging reading experience and a lingering intellectual satisfaction. Loya demonstrates a broad literary toolbox as well as a storyteller's instinct to leave us with substance beyond the pages. She sets a high bar for her future work, it will be a treat to see what she produces next!

The Laboratory Assistant was exactly the kind of atmospheric historical fiction I love.

Set during the Russian Revolution, this story combines gothic suspense, romance, political unrest, and scientific ambition into a compelling and immersive read. From mausoleums and family crypts to a creepy old laboratory filled with secrets, the atmosphere practically drips off the page.

Mariya was an easy protagonist to root for. As her family’s world crumbles around her, she finds herself working alongside the enigmatic Dr. Nikolas Rodin, whose research may change everything. What begins as a story of survival quickly becomes something much darker and more complex.

The gothic elements were my favorite part of the novel. The sanatorium setting, mysterious experiments, inspector investigation, and growing sense of unease gave this book strong dark academia vibes. There were several moments where I genuinely wasn’t sure where the story was heading, and I loved the suspense that created.

I also appreciated how the novel explored the intersection of science, morality, obsession, and love. The “mad scientist” undertones added another fascinating layer to the story without turning it into outright horror.

If you enjoy:
🖤 Gothic historical fiction
🖤 Dark academia vibes
🖤 Women in STEM
🖤 Atmospheric romance
🖤 Russian Revolution settings
🖤 Mystery and suspense

I definitely recommend picking this one up.

Thank you to NetGalley and the publisher for the advance copy. All opinions are my own 📚✨

Favorite takeaway: This felt like a gothic romance wrapped inside a historical mystery, with just enough creeping dread to keep me glued to the pages 🖤

What a beautiful, bittersweet story!

4.5/5 ⭐️
(Rounded up)

The Laboratory Assistant is set against the backdrop of revolutionary Russia in 1916. It paints a vivid picture of the hardship, poverty and uncertainty experienced during the era while also exploring the unsettling beginnings of modern medicine.

Mariya and Nikolas are flawed, believable characters whose relationship develops amidst extraordinary circumstances. The writing is thoughtful and engaging without feeling overly dense. I did find myself wishing for a little more clarity in a couple of areas. The shifts in point of view occasionally took me a moment to recognise, and the alternating use of names and titles could be distracting at times. I also would have loved to learn more about Nikolas' illness. I understand there may not have been a formal diagnosis or terminology for his condition in 1916, but given that his closest friend was a psychiatrist, I kept expecting a little more insight into what he may have been experiencing.

The narration was clear and easy to understand, especially as it was read by the author. As time went on, I could hear the increase in confidence and found it more engaging to listen to as it progressed.

Overall, this is an interesting blend of historical fiction and gothic romance that I think will appeal to readers who enjoy immersive historical settings, morally complex characters, and stories that explore the ethical boundaries of early medicine.

As always, thank you to the author, publisher and NetGalley for providing me with an ALC in exchange for an honest review.

The Laboratory Assistant is a historical gothic romance set on the cusp of Russia's February Revolution. Mariya Sokolova, the heroine, is from an aristocratic family fallen on hard times, as she's forced to seek out work in order to support her dying mother and sisters. By chance, she finds work as the assistant to the brilliant and charismatic doctor, Nikolas Rodin, who seems plagued by an inner darkness as he stops at nothing to find a cure for tuberculosis. As their relationship develops, she too is sucked into his world of madness and transgression, as the world around them slips further into chaos.

Loya does a wonderful job bringing the prose and magical realism of 19th Century Russian literature into the modern era. She captures the tension and philosophy of Crime and Punishment but with a modern perspective on mental illness and science -- as well as a steamy romance that would definitely not have passed the 19th Century censors!

I highly recommend this book to anyone who enjoys historical gothic fiction with a strong romantic subplot, especially if you're interested in World War I era Russia. Additionally I think this is a great gateway book into the Russian classics if you're not familiar with them, especially since Loya simplifies some of the Russian naming conventions that so often befuddle Western readers.

Should you enjoy this book and want more of that vibe, I'd recommend Crime and Punishment by Dostoevsky, Queen of Spades by Pushkin, and Master and Margarita by Bulgakov.

First and foremost, I am going to point out that the narrator of this book is also the author. I hate when authors do, this because they read the book like they are simply reading the book. It is not a true narration. Multiple times, I had to stop this book and restart it over the course of a few days. The authors tone was extremely whiny and very nasally. She does not have a good voice for audio recording, and she should take note of that because…

The book could have been phenomenal-had it not been for that.

The storyline was very good. It was set in Russia in the early 1900s. It had a lot of historical value in dealing with the crisis that Russia was going through along with the resistance that the Russian government had and multiple illnesses that were occurring at the time in that country.

It’s just so sad that the book was probably pretty well written, but because the author did not pay to have a good narrator or maybe just thought she could narrate it better, It just really fell short.

I would give it 2 1/2 stars, but I didn’t wanna rank it at two; I went ahead and generously gave it three. Had she had a true narrator read the voice, it probably would’ve hit closer to a four or 4 1/2 star. It got extremely confusing at times because she did not change her voice for each person that was talking. Thus, why I started it over five or six different times realizing that I didn’t even know what the f*ck was going on and who the f*ck was who.

Thank you to the author and NetGallery for the ARC.

I expected almost a Frankenstein romance with paranormal elements. Instead, The Laboratory Assistant delivered a bleak account on the eve of the Russian Revolution of Mariya, an impoverished young woman caring for her widowed mother and younger sisters, who finds work in the lab of Dr. Nikolas Rodin, a brilliant biomedical scientist on the verge of discovering a cure for tuberculosis. There is no literal monster or ghost, only the shadows of Nikolas' mental illness and the growing love between him and Mariya, as she learns to read him and his loyalty and dependence on her grows.

The writing is sometimes hard to follow. Although most of the story is told from Mariya's POV, as more characters are introduced, POVs can switch momentarily in the middle of the action. The subject often changes too: rather than Nikolas, he's the scientist. Rather than Viktor, he's the psychiatrist. Rather than Mariya, she's the dancer or 20 year old woman.

Nevertheless, the plot carries forward well, as we follow the decline in Mariya's mother's, sister's, and then her own health due to tuberculosis and Nikolas' increasing madness, off the meds, to find the cure. Meanwhile, the city of Petrograd is a pressure cooker with the Bolsheviks and students increasingly clashing with the police. All of it sweeping everyone into final confrontation with high stakes of life or death.

This isn't the sort of book that had me cancelling plans to keep reading, but I still had a really good time with it.

It was quite different from a lot of what I've been reading recently, which I appreciated. I liked the characters, liked the story, and was happy with how everything wrapped up in the end.

That said, it wasn't one of those books that completely grabbed me and took over my life. I found myself reading a bit, putting it down, then coming back to it. I was always interested in what was happening, but I never had that "just one more chapter" feeling.

There were also a few moments where I got a little confused and had to go back and reread sections because I wasn't quite sure what had happened. Once I figured it out, I was fine, but it happened enough that I noticed it.

My biggest frustration was actually the formatting on my Kobo. When I downloaded it through NetGalley, it showed as over 1,100 pages and the story didn't seem to start until around page 600. Obviously that's not the author's fault, but it did make for a slightly strange reading experience.

There was also one phrase that kept popping up throughout the book that I personally wasn't a fan of, and after a while I couldn't stop noticing it.

I still enjoyed reading it. It was interesting, different, and kept me curious enough to keep picking it back up. Sometimes that's exactly what you want from a book.

This was….whew, this was not good, and I’m genuinely surprised that this book has over a four star rating! Perhaps the traditional book format is what is saving it. The premise sounded so intriguing but the execution was flawed on many levels.
Firstly, the author narrated this audiobook, and it was, well, as I’ve already mentioned…not good! Quite monotonous, with an accent out of line with the setting.
My main problem, and it was a big one, was with the author’s word choice and style. I have to wonder if somewhere along the way, an editor encouraged her to use different ways to name or refer to each character. We go from their names to ‘the assistant,’ ‘the scientist,’ ‘the psychiatrist,’ ‘the dancer,’ ‘Mariya’s lover,’ etc. In a two minute sample, Dr. Rodin was referred to as ‘the scientist’ seven times. It was silly and repetitive. This, in combination with the awkward audiobook narration, took me right out of the story more often than not. Also I feel like there were some underdeveloped storylines that went nowhere, such as hinting that the doctor’s ailment was supernatural only to lead you firmly down the path to it being “madness” in the next breath. I should probably have DNFed, but I’m no quitter! I felt a total lack of connection with all the characters. It’s a shame because I do feel this book had so much potential!

The Laboratory Assistant by Natalia Loya immediately caught my attention because of the title. As someone who used to work as a lab assistant, I was intrigued to see where the story would take me, and I thought this would be a nice change from my usual reads.

I really enjoyed the dark and eerie atmosphere of this audiobook. Natalia Loya does a great job creating vivid imagery of Petrograd in 1916, especially with Russia on the brink of World War I and revolution. The laboratory setting, unsettling experiments, and mysterious atmosphere gave the story a gothic feel that kept me curious.

I will admit that the first three chapters were a little difficult for me to get through, and there were definitely some gruesome moments that caught me off guard. However, once I settled into the story, I appreciated the unique combination of historical fiction, gothic elements, science, and romance.

Mariya’s struggle to support her family while working for the reclusive Dr. Rodin added an emotional layer to the story, especially as tuberculosis and revolution begin affecting her family and the world around her.

Overall, if you enjoy gothic, eerie historical fiction with a touch of romance, The Laboratory Assistant is definitely one to add to your TBR. 🖤📚

Thank you @netgalley and Natalia Loya for giving me the opportunity to listen to the audiobook of The Laboratory Assistant. This review is from my own accord.

The Laboratory Assistant was atmospheric, lush, and immersive.
In 1916 Petrograd, we follow former aristocrat Mariya struggling to make ends meet for her family, while the threat of revolution and consumption (tuberculosis) arise. When she meets mysterious scientist Nikolas Rodin, her life shifts dramatically.
I felt like this was incredibly interesting. This is slightly outside of my typical genre reads, but I couldn’t put it down. Every time I would go to pause, the story would shift and I simply had to continue. I had no clue what would happen or how the book was ending, I loved that. The writing was cohesive and highly thought out. I personally loved the romance.
I struggled a bit with the third person POV, switching from following primarily Mariya to occasionally other characters in a way that felt abrupt. It took a second to be like “oh wait this isn’t Mariya anymore”. That’s my only complaint, and it’s so minor.
I loved how the author leaves room for interpretation with some subtle nuances, and addresses heavy topics with such grace. This story will stick with me for its originality and detail.

The Laboratory Assistant - Natalia Loya

This is definitely one of my favorites for the year. Mariya, Sofia, Victor, and Nikolas were some of the most interesting characters that I ever read. And the chemistry and tension between Mariya and Nikolas was phenomenal. I loved the setting and all the details that went into this book. It had such a gripping atmosphere that kept me reading and I couldn’t put it down. I love reading historical fiction that isn’t Regency era England, and this being set in Russia during the revolution was just so interesting to me. Especially with the female main characters being of the aristocratic class and Sofia’s interest in the revolution. I also really do love the doctors and seeing how the STEM field was written durning this time. I will definitely be reading more from this author, and I recommend you all as well.

Eldest daughter Mariya Sokolova is trying to keep her poverty-stricken household comprising of two dear sisters and a very ill mother afloat after the untimely death of their patriarch knocks them off aristocracy's high horse. Enter Dr. Nikolas Rodin, who offers her the position of -- well, you guessed it, laboratory assistant, and we are thrown into a macabre basement as he will stop at nothing to find a cure for consumption. Meanwhile, as the political unrest in 1916 Russia grows, Mariya's sister Sofia -- training to be a secretary, gets entangled in the Bolshevik rebellion. As a STEM nerd, it was also really delightful to see Mariya learn the ins and outs of working in a lab as enticing chemistry blooms between the duo.

The Laboratory Assistant is so UNIQUE in its setting and premise and is a gothic debacle with well-rounded characters with distinct traits, flickering moral compasses and dark secrets. NOW, it'd have been really exciting to delve a bit more into the darkness, and to resolve the arc of Nikolas' mental unstability with more certainty and reason -- BUT the underlying themes made it a very enjoyable read nonetheless and I look forward for more from the author.

The Laboratory Assistant was an interesting read that ultimately landed at 3 stars for me.

The premise hooked me immediately: a doctor with a Jekyll-and-Hyde-like darkness falls in love with his laboratory assistant and will do absolutely anything to protect her. Set during the Russian Revolution, the political unrest creates a tense backdrop, and I found myself genuinely invested in both the story and the characters.

My biggest struggle was with the writing style. The dialogue often felt overly formal which, to be fair, fits the time period to an extent. What pulled me out of the story more was the narration itself. Characters were constantly referred to by name before switching to titles like “the doctor” or “the assistant,” and it gave the prose a detached, almost textbook-like quality at times.

One thing that’s worth mentioning is that I experienced this as an audiobook provided through NetGalley, narrated by the author. Unfortunately, the narration didn’t work for me and made it harder to connect with the story. I honestly think if I had read the text instead of listening, this could have been a 4-star read.

Despite my criticisms, I did care about these characters and wanted to know how their story ended. The central relationship was compelling, the historical setting added plenty of tension, and there was enough here to keep me engaged from beginning to end.
