Some girls choose love. Some choose pain. Sophie and Caroline chose both.
They were strangers. Different lives, different worlds, but the same mistake — falling for men who were never truly theirs to begin with.
One week apart, both women were found dead. No struggle. Just silence.
Detective Angelina von Stein wasn’t supposed to share this case. But now she’s working alongside two men she never wanted on her team, especially the one who’s made her feel too much for far too long.
The trail leads to one therapist’s office. A place that promised safety… and delivered anything but.
The deeper they dig, the darker it gets. Obsession, grief, control, and the quiet unraveling of someone no one thought capable. Because the most dangerous kind of hurt… is the one that learns how to hide.
Voluntary Pain is a sharp, intimate psychological thriller about secrets, patterns, and the kind of love we never admit out loud.
Enter for the murder. Stay for the part that hits too close to home.
After all… haven’t we all, at least once, chosen something we knew would hurt?
Irina Semikop writes psychological thrillers that go beyond crime and mystery, diving into the complexities of human behavior. Her debut novel, Voluntary Pain, explores not just danger and secrets, but the choices, contradictions, and hidden sides of the people who make them.
She finds inspiration in travel, in watching people, in overheard conversations that reveal more than they intend. For Irina, thrillers aren’t about shock value – they’re about capturing life in all its layers and turning it into stories that feel unsettlingly real.
Voluntary Pain was a pleasant surprise for me! The book follows a detective Angelina and her team as they work to unravel two seemingly unrelated murders and the possible connections between them, as well as a possible ✨romantic connection✨ for Angelina along the way.
Don’t let the page count scare you off; the pacing made the length of it feel very manageable. This book was a page-turner for me not because I was chasing cheap thrills, but because the author set the groundwork to really get you invested in Angelina’s life just as much as the case itself.
Overall, I think the story was very well crafted. It’s apparent how much thought and care went into creating all the pieces of this story. It’s a murder mystery but in a very realistic, grounded kind of way. I felt like I was watching over the shoulders of a real detective team. Every character felt like a real person, every new piece of evidence and dead end would be plausible in the real world. I enjoyed the plot twist at the end! I wasn’t fully expecting it but it still fit reasonably within the context of the story. The author didn’t just pull something completely random and ridiculous out of left field for the sake of having a crazy plot twist. This book feels exactly like watching a good episode of a crime show. If you like CSI, NCIS, SVU etc this book is the one for you.
Now I will say, although not unpleasant, I did find myself slowing down when it came to the parts that focused more on Angelina’s romance, or when she spent time with her best friend or even her mom. I recognize those moments are important for building up the characters but I selfishly wanted to get back to the case LOL. Found the workplace romance a little ehhhhh, but I’m not counting that against the book as it’s just personally not my style.
Another thing to keep in mind: this book spares NO detail. Nothing goes unwritten and nothing is summarized/glazed over. Every word of every conversation, every thought in Angelina’s mind, every single move anyone makes, the details of every outfit, every twitch in someone’s face, you’ll know it all. When Angelina gets home from work, you’re gonna know every single thing she did from the moment she stepped in the door to the moment she lays down for bed. This is a 50/50 for me because while it does immerse you in the story, sometimes I felt it was just a tad overly descriptive.
Thank you so much to Irina for giving me an ARC of Voluntary Pain! Can’t wait to see what comes next for Angelina and the team!!
I wasn’t sure what to expect going in, but Voluntary Pain surprised me in the best way. It’s part murder mystery, part psychological thriller, and part slow-burn character study that kept me hooked.
First off, the case itself was gripping. Two women dead under eerily similar circumstances, no signs of struggle, and all roads leading to a therapist’s office? I was immediately pulled in. The investigation unfolded like a really well-written TV crime drama—sharp dialogue, layered characters, and enough twists to keep me guessing without ever feeling random.
What really stood out, though, was the balance between the mystery and the relationships. Detective Angelina von Stein felt authentic and flawed in a way that made her easy to root for. The banter between her and Liam gave the story a bit of levity (I was laughing out loud at the mango scene), but it also made the quieter, more emotional moments land harder. Their dynamic added depth without taking away from the suspense.
The pacing is on the slower side at times, especially when it leans into character development, but I didn’t mind—it gave me space to connect with the team and really sink into their world. And the ending? A twist that was both shocking and well-earned.
Voluntary Pain is more than just a thriller—it’s a thoughtful, unsettling exploration of love, control, and the choices we make even when we know they’ll hurt. I’ll definitely be picking up the next Angelina von Stein book.
Thank you to the publisher for the ARC. All opinions are my own.
I received this book as an ARC and honestly didn’t know what to expect, but I ended up really enjoying it. I completely fell in love with the main character (maybe it’s also because she has a German last name too 😄), but more than that, she felt like a real person to me. The writing style is rich and immersive, and the dialogues read almost cinematically, like a well-written TV drama. The book has the right balance: it gives a sense of procedural detail without being overloaded with investigative facts that might put off readers like me. And to my surprise, I also really enjoyed the romantic thread (oh god🥲, I even caught myself wishing for more of it here!). I realize that might have shifted the book into a different genre, but it worked so well. Why four stars ⭐️? The pacing dragged in a few places. Maybe that was intentional, but at times I wished the story would move a little faster. If the author tightens this up in the next book, making it a bit shorter and more dynamic, it would be sooo cool.
Voluntary Pain was a darkly compelling debut that gripped me with its secrets and haunting psychological depth. I found Voluntary Pain to be an intriguing read, full of quiet tension and hidden layers that kept me curious about what would surface next. It’s the kind of thriller that pulls you in with its secrets and leaves you unsettled in the best way.
Likewise, I thought the strength of Voluntary Pain was in its layered psychological depth. The way Irina Semikop captured the hidden sides of people and how love, secrets, and contradictions can quietly drive their choices was intriguing. The murder thread added intrigue without overshadowing the more intimate, unsettling tension, which made the story feel original and thought-provoking. On the downside, the pacing felt slow at times since the focus leaned more on atmosphere and inner struggles than constant twists, and a few of the relationships could have been explored with sharper detail. However, the book’s eerie tone and character-driven suspense made it a compelling debut.
Irina Semikop’s writing style was moody and reflective. It dug into secrets and unspoken feelings. Rather than racing through shocks and twists, she built a slow, uneasy tension by focusing on her characters’ inner lives, making the story feel intimate, layered, and haunting.
Overall, Voluntary Pain was a psychological thriller that wove a murder mystery with an intimate look at secrets, hidden desires, and human contradictions. Instead of nonstop twists, it was a slow build with uneasy tension through introspective, and atmospheric writing. Though the pacing was most likely deliberate, I found it intriguing and compelling debut.
Thank you to Net Galley and Victory Editing NetGalley Co-op for a complimentary copy in return for my honest review.
5⭐️ This was a unique psychological thriller. There was the mystery/thriller part of it but there was also a slow burn romance brewing throughout. I loved the banter between the characters. The character development was amazing. I liked the slower pace because it helped to really understand the story. The last 10% of the book will slap you in the face though. The cliff hanger at the end I was like wait what 🤔 im intrigued to see what happens next for Angelina. If you like psychological thrillers this is a must read!
I had a love/hate relationship with the main character in this book. There were moments when I loved the way she worked through the puzzle pieces of the mystery and other times where she came off clueless.
I also loved the humor added to the book as you don’t always get that in thrillers but some of it was overkill when the storyline slowed down in the middle. That said, you had a true sense of the characters personalities and it made you laugh at times. I’m not much of a romance reader, but if you like that aspect in your thrillers, this had a balanced vibe of mystery, love and humor.
Overall this was a good read. Very fast paced and the pages flowed quickly. I don’t think the plot would have been impacted if it was shortened some but would definitely recommend giving it a shot!!
I received this as an e-ARC and will be voluntarily be giving my honest review. This book was very well written. This is a about a detective Angelina and her team trying solve two different case that are not related murders but possibly have the same connection. This was very detailed and gave me CSI vibes and had wanting to keep turning the pages! I love how the romance sparked between detective Angelina and detective Liam. I definitely want to see more of these two and the new team play out! Need the next book and cant wait!!
“Voluntary Pain is a sharp, intimate psychological thriller about secrets, patterns, and the kind of love we never admit out loud.
Enter for the murder. Stay for the part that hits too close to home.
After all… haven’t we all, at least once, chosen something we knew would hurt?”
This book is simply magnificent, it had me on the edge of my seat and completely captivated the entire time.
And if you like plot twists, give this book a try! I didn’t see it coming one bit! So well written with little clues here and there so when it comes to it you can start to notice everything you missed!
The characters are funny and witty and the little tie in of romance is so well done! It doesn’t take away from the plot or the story, it fits in perfectly!
Angelina is by far my favourite detective and I’ll definitely be keeping my eye out for more of these books!
Honestly I really loved this. I don’t give 5 stars out often (I’ve had 4 included a re read) but there was not one thing I could fault about this
The case itself was so intriguing like yes I did guess something but I was still hooked to see what was going to happen and how everything would play out
I’m not a big romance girlie but omg Liam 😍 the way he communicates and how much he cares for Angelina omg my little heart
I also loved that there was no need to leave the chapters off on a cliff hanger cause I feel like that cheapens a book sometimes. Like I only want to read cause you left me on a cliff hanger but this book doesn’t have that, the story was interesting enough on its own that I kept reading because I wanted too
I know it’s a long book but it never felt like that while reading
Voluntary Pain is not your typical thriller — it’s a story that gets under your skin in quiet, unsettling ways. Following Angelina, we’re drawn into a world where desire and danger blur, and every choice feels like it carries both intimacy and threat. What begins as a seemingly normal life quickly turns into a layered exploration of control, trust, and the hidden cost of love.🖤
What I loved is how the book keeps you on edge without relying on loud shocks. Instead, it builds a slow tension — through everyday moments that start to feel heavier, through conversations that hold double meanings, through emotions that spiral into something darker. It’s the kind of psychological thriller that doesn’t just play with plot twists, but with your mind as you read.✨
The romance elements are there, but they’re twisted with risk, making every connection feel dangerous and magnetic at once. The writing lingers on atmosphere, details, and the fragile line between passion and pain.🦋🖤
If you enjoy thrillers that focus on the psychological — manipulation, obsession, vulnerability — paired with the emotional pull of romance, this one will keep you hooked. It’s haunting, sharp, and thought-provoking in all the right ways.✨
Got this as an ARC and I’m still thinking about it days later. It gave me Sharp Objects meets Criminal Minds vibes, in the best possible way. Voluntary Pain isn’t your average thriller—it’s smart, emotional, and filled with tension. I especially loved the friendship dynamics between Angelina and Nico. Would 100% read more from this author.
DNF @ 21%. I almost gave up on this book earlier than my 20% mark because of how often (huge understatement) words like “smirk,” “sterile,” “precision,” “shot back,” and “mock” kept popping up. Repetition is one of my biggest pet peeves when it comes to books/reading and I just can’t help but notice when it happens too much.
Following up on that, I’m not sure if the book was trying to sound hip and clever, but it didn’t work for me. The conversations between characters felt really cold and transactional, like they were just going through the motions.
On top of that, the cases the main character worked on didn’t grab me at all. There was no hook, no sense of mystery, and nothing about the victims that made me curious. The writing was very matter-of-fact, or as the author might say, “sterile.” It felt too clean and polished but without any real edges or depth to make it remotely interesting.
Also, the book seemed to rely heavily on police procedurals (which I’m a fan of), but it didn’t even follow any of the basic elements of that genre. There was no real fact-finding, no following clues, no investigative work etc. that you usually expect. It just felt like a checklist of updates without the substance behind it.
What made things worse was that there were a lot of repeated bits in the dialogue, especially when updates about the cases got passed around from one character to another. This not only added unnecessary length to the book but also killed any momentum. Because of all the back-and-forth, the mystery dragged on without building any tension. By the time the story finally dropped a clue or puzzle piece, all the excitement was gone for me.
Maybe I’m just an outlier seeing as how the majority have given this book a 4-5*. But I think part of my huge disappointment comes from expecting a fast, clever thriller (similar to what Steve Cavanagh writes). Instead, this felt more like literary fiction ie. slow and methodical, without the sharp thrills I was hoping for.

Many thanks to NetGalley for making this ARC accessible!
I love a good murder mystery that keeps me guessing, and Voluntary Pain definitely delivered on that front. It’s more than just a whodunit—it blends murder mystery with psychological thriller elements and even a slow-burn romance. The case itself was intriguing, with plenty of unexpected layers of affairs and connections between suspects. As the story unraveled, I found myself deeply invested in the “why” behind the murders. The deeper it went, the more it highlighted how easily something like this could happen to young women in real-world situations, which made the story hit even harder.
The reason I rated it 3.75 stars instead of higher is because the forensic side of the investigation was relied on heavily, but we only saw it mentioned through quick phone calls to team members. There was very little detail about what the forensic team actually did to get their information, and I found myself wanting more substance there. Additionally, some of the lines the detectives crossed felt unethical and unrealistic for a standard case, which pulled me out of the story a bit.
Overall, it’s a layered, thought-provoking mystery with strong psychological elements that fans of darker thrillers will enjoy—I just wish the investigative details were fleshed out more.
Really solid read. The characters were super well done (Angelina especially felt really real), and the story had this slow-build tension that I was into. The psychological stuff was subtle but, hit hard. Definitely one of the stronger parts of the book.
That said… it was long. Around the halfway point I started skimming a bit and I think that is why it took me longer than planned/hoped to finish. Not because it was bad, just felt like it dragged in some spots.
Still, glad I stuck with it. If you’re into slow-burn thrillers and don’t mind a bit of a slower pace, I’d say give it a shot!
I really enjoyed this book for a variety of reasons, First, it read like an episode of law and order. I didn’t feel bored or confused. Second, I actually cared about the characters and their relationships. They felt real and authentic and the banter between them was pretty funny (I cried laughing while reading about mangos) Thirdly, it’s very unique from other murder mysteries. The ending is a total 180 plot twist, but carefully developed through what I can only assume is realistic police work. I felt involved as I went through the investigation with Angie. There was still a plot twist but it wasn’t super unexpected, as the team laid out the ground work to come to the conclusion of the book, which felt refreshing.
The book did feel a bit slow when it focused more on the relationship development between Angie and Liam, but I also kind of enjoyed this? The relationship didn’t feel rushed, especially considering the apprehension to a relationship in the first place lol.
Definitely looking forward to reading more of irinas work in the future :)
Voluntary Pain is a psychological thriller about a detective named Angelina and her team working to solve a series of murders. The book differs from other mysteries I've read; it felt like I was watching an episode of Criminal Minds or SVU. At times, the writing became overwhelming with excessive details, which could detract from the story. However, I admire the author's attention to detail and the level of research that went into the book, as it clearly reflects her dedication to the story. I'm looking forward to reading the second book!
Thank you to Netgalley and Victory Editing Netgalley Co-Op for the ARC.
4.5 ⭐️ I received the Kindle version of this book as an ARC, and this is my honest review. To me, Voluntary Pain didn’t feel like just a book. It read more like the start of a whole series, which was such a refreshing change from the formulaic thrillers I usually see. The story isn’t built on cheap twists but on strong writing and real depth, and yet it still moves fast. I was surprised by the length at first (thrillers are usually much shorter these days), but once I started, I couldn’t put it down. If anything, I almost wished there was more 😌. The humor works really well, and the dialogues feel sharp and alive. I’d honestly love to see this adapted into a Netflix series, because it already has that vibe.
The characters, especially Liam and Nico, stood out to me. They feel layered and real, not cardboard cutouts. Sometimes I wished for a bit more focus on the female lead, but Liam in particular really caught my attention😅, and I hope he’s developed even further in the next books. Literature needs more male characters like him: not cliche alpha-males, not overly sweet boys, but real, complex men with flaws and emotions.
Overall, it’s a very strong debut. It’s not a “perfect” book (at times the level of detail slows things down a little), but it’s smart, original, and absolutely worth reading.
What an engaging read! The characters are relatable and interesting! There is some romance and quite a bit of witty banter. This one should definitely be turned into a Netflix movie!!
Thrillers and detective mysteries aren't usually my go to genre but the description of this book caught my eye. The writing style was a bit choppier and dictated than I usually prefer, but I definitely got sucked in. Trying to anticipate twists is one of my favorite things about reading and seeing how on point or far off my theories are. Voluntary Pain did a good job of keeping my suspicious brain looking for clues to "who done it". As a habitual romance reader, I craved more of that story-line but am hopeful that the next book will dive deeper into Angelina's love life alongside her detective work. The ending of this definitely had me going "Wait what?! That's the end?". Not because things were unresolved from the plot (thankfully) but because the author did a good job setting us up to anticipate another book release. I look forward to character developments in Book 2.
It was a bit long. But this was a good read. There was everything you would expect in a Thriller/Suspense Romance. Yes, all three and it was well paced with the twist in this book. The romance was like I like it in a book. It's present but not the main part of the story, and it's on the clean side, use your imagination. The plot was interesting and the characters who were suspects were sketchy. They all had motive except for one eccentric personality in the mix. I am assuming there will be a sequel to the main Investigative Characters in this book.
This book took me by surprise. I wasn’t expecting to get so emotionally invested in the characters! The pacing is smooth, and while it’s a longer read than I usually go for, the writing keeps you hooked. I read it as part of an ARC campaign and I’m genuinely impressed. It deserves to be adapted into a series.
I got this book early as an ARC reader and I’m so grateful I did! What a ride. I loved the balance between the police procedural aspects and the personal storylines. Nico is hilarious, Liam is intense, and Angelina feels like a real woman thrown into impossible situations. Will definitely recommend!
Voluntary Pain isn’t a fast-food thriller. it’s a slow-cooked, layered story that lingers. I received the ARC and wasn’t sure what to expect, but I’m glad I took the chance. Yes, it’s long, but the writing is cinematic and full of life. Some parts reminded me of Mindhunter, but more emotionally driven. Loved it.
ARC copy. What a complex and thoughtful thriller. The mystery is sharp, but what I loved most were the inner lives of the characters. Angelina’s struggle between vulnerability and strength felt authentic. I do think the book could’ve shaved off 10–15% without losing impact, but it’s a strong, memorable read.
Reading Voluntary Pain is like reading a season of NCIS: exciting murder cases, intriguing suspects, funny coworkers, one great detective and even a romance coming along.
Two women are found dead within just a week of each other. Strangely, there are no visible signs of violence or struggle. Their mysterious deaths raise troubling questions and draw the attention of the authorities.
The investigation falls into the hands of Detective Angelina von Stein, a sharp and determined investigator who also carries her own personal struggles. As she digs deeper into the women’s lives, Angelina encounters two men who quickly become central to her case. Their presence doesn’t just affect her work — it forces her to confront vulnerabilities she would rather keep hidden.
The trail eventually leads Angelina to a therapist’s practice. Supposedly a place of safety and healing, it instead conceals dark truths and dangerous dynamics. As the layers of secrecy are peeled back, Angelina realizes that what happened to Sophie and Caroline is tied to a disturbing exploration of power, love, and the human tendency to sometimes choose pain — even knowingly.
With Voluntary Pain, writer Irina Semikop has definitely shown that she knows what she’s doing. The characters are well thought and have their own personalities and styles. You’ll know what detective Von Stein is thinking - all of the time.
However, this also slowed down the pace of the story. Whilst there were many scenes in which I rather liked reading all about Angelina, sometimes it just felt like a bit too much. During an exciting scene in which she almost escapes I do not want to know what would be the wise choice to do. I just want to read her doing it anyway.
If you’re looking for a fast paced thriller, this might not be the book for you. However, if you’re looking for a psychological thriller that leaves you thinking about what choices you would make, Voluntary Pain should definitely be your next read.
I want to thank Irina Semikop for sending me an advanced reading copy in return for my honest review. Can’t wait to see what lies ahead for Angelina!
"Voluntary Pain is an electrifying psychological thriller that immediately grabbed my attention and refused to let go. From the first chapters, I found myself completely absorbed—by Chapter 5, I didn’t want to put it down, and by Chapter 16, I was still in the dark, desperately curious to unmask the killer. That’s rare for me since I usually figure out mysteries early, but this author kept me guessing and theorizing at every turn.
Every twist is masterfully executed: just when I believed I had everything solved, a new complication was revealed—like John becoming central to the investigation, or the shocking turns around Chapter 50 that made me question whether my suspicions about Arthur's wife were really on the mark. The plot draws you in and refuses to let you settle, constantly pulling you towards new suspects and shocking discoveries.
What truly sets Voluntary Pain apart is how immersive and unpredictable the journey feels. The story is built on layers of secrets, with each revelation making me both gasp and fervently read on. The tension doesn’t let up. By the end, when the shocking team-up and the real accomplice were revealed, I was stunned—and absolutely needed more.
This novel masterfully balances deep character dynamics with relentless suspense. It deliberately keeps the reader off-balance until the final, wild reveal—like Arthur’s wife’s involvement and that final scene with the lawyer, which left me reeling and wanting the next installment immediately.
If you want a thriller that keeps you up late, guessing until the end, Voluntary Pain is a must-read. I am so thankful for the chance to read this ARC, and I can’t wait to see what this author does next."
Psychological thriller on steroids! I love me a deep mystery with raw dynamic layers, incorporating a crime investigation element.
Detective Angelina von Stein was told to keep this case under wraps, however now she's stuck working with two guys, she never wanted on her team. As the plot builds up, the trail leads them to a therapist's office, which promises to be a safe haven but delivers a whole lot of crazy instead. The deeper they dig, the wackier it gets. As the depth of their inquiry increases, so does the darkness. Fixation, and sorrow with a quiet deterioration of someone, nobody thought had the capacity. For the most dangerous form of betrayal and hurt..is the one that masters the art of hiding.
The suspense was excellent, with the trio angelina, liam and nico being multilayered. Bringing raw emotions and comical moments with a well paced storyline, keeping you engaged with a complimentary writing style! awesome! There are some dark, twisted events that happen in this book, that amp up the stakes, perfect for spooky season.
I am about to hit the half way point of life, so I need a book that will suck me in and keep me wanting more. Detective series are my jam. I normally finish books in a few days however, this one took a while, the pacing was a slow burn where it felt like it dragged on. The romantic subplot felt unnecessary and overdone BUT please note romance is not my favorite genre so I am bias here. This book had more of a friends to lovers vibe than a police investigation.
The writing is undeniably beautiful and descriptive, with moments that really shine. I stuck with this book until the end because this author really knows how to paint a picture where you see the smallest details as you read. Her story is fluid and cohesive. AND the way the murders were done… *chefs kiss* and it had so much CSI potential if that was the focal point.
If you love beautiful written, slow burns with murder & romance, this might be your kind of read. For me it was not the page-turner I needed. More crime, less inter office drama would’ve made it a 5 star for me.
Wow. Voluntary Pain had me hooked from the very first chapter. The setup :two women, one week apart, found dead with no signs of struggle was chilling, and I immediately wanted to know why. Detective Angelina von Stein is such a complex character. I loved that she wasn’t painted as perfect. She’s smart and determined, but she’s also dealing with her own inner mess, which made her feel so real to me.
What I enjoyed most was how this wasn’t just about solving murders. The story digs into the choices people make when they’re in love, scared, or desperate, and how those choices ripple out in painful ways. It’s haunting, but also strangely relatable.
There were moments the pacing slowed a little, but honestly, I didn’t mind because I was invested in the characters. The twists kept me on edge, and I loved that some of them completely blindsided me.
If you’re into psychological thrillers that feel emotional and raw, rather than just shocking for the sake of it, this is one I’d definitely recommend. I’m already looking forward to the next Angelina von Stein book!
There’s no doubt that Voluntary Pain is a well-crafted novel. The characters are compelling, the plot is intelligently structured, and the atmosphere is thick with tension and emotional complexity. I especially liked how the psychological aspects of the story were handled — subtle but impactful. Angelina felt real to me, which doesn’t always happen with fictional detectives. However, for my personal taste, the book was simply too long. I found myself skimming parts around the midpoint, not because it was boring, but because the pacing dipped and I felt like the story could have been just as powerful with 100 fewer pages. That’s not a knock on the author’s talent — the writing is smooth and engaging but I do think some editorial tightening could’ve made the experience stronger. In the end, I’m glad I read it. I’d recommend it to readers who enjoy slow-burn thrillers with emotional depth, but be prepared: it’s a long read. That said, the story stayed with me, and that’s always a good sign.
