The Burn Line

Rate this book
There's something lurking in the stifling darkness and labyrinthine tunnels that run below London... something old, something vicious, and something very, very hungry.

It's the hottest summer on record and London is dying. Prices are high, pay is low, and stressed commuters are packed onto London Underground trains again like the pandemic never happened. To add to the misery, the temperatures underground just keep climbing and climbing, the heat trapped in the clay with nowhere to go.

Then one fateful morning five travellers on an unlucky tube carriage find themselves bound together as witnesses to a single horrific event - an event they can't quite seem to remember.

They make an unlikely team - a weary tube driver, a disillusioned civil servant, an ambitious city trader, an overwhelmed hotel worker, and an unhoused young man just trying to get by - but now they must come together to confront what they have seen and stop it in its tracks before it kills them all.

From the dark and twisted mind behind Thirteen Storeys, Family Business, and podcast sensation The Magnus Archives, The Burn Line is a sinister and socially conscious horror masterclass perfect for fans of Stephen King, Jordan Peele, and Black Mirror.

First of all, thank you to this book for keeping me company throughout one of the worst heat waves we’ve seen in decades - at least I was battling only heat and not monsters, unlike the characters here! 💀

London is trapped in a summer heatwave, at the tail end of the COVID pandemic, and something uncanny is happening in the London Underground. Six passengers on the Tube, as if waking from a dream, blaming the intense heat for their drowsiness. All smelling something sweetly rotten. All, in some way, covered in a weird, ashy grease. They’re confused, but after some shared glances, they continue on their journey, living their lives.
Not for long, though. Because something hungry is dwelling in the shadows of the Underground, and it’s not afraid to venture out to seek its next dinner. Because at the beginning of the ride, there were seven commuters.

Honestly, I almost hesitate to put Burn the Line in the horror genre box and call it quits. It has a pretty damn good atmosphere build-up - noises and smells with no obvious source, the eyes detecting no danger while the body knows something is near and fills with adrenaline and fear. Some pretty spooky scenes had me almost looking over my shoulder into the darkness of my bedroom. Yet I feel that most horror readers would be a bit disappointed going in expecting to be scared or shocked. At its core, it’s a character-driven social commentary (thought on what topic, I won’t say, that would be a spoiler in my eyes) wrapped in a horrifying tale similar to an urban legend.
Although I have to say, the last third of the book took a swerve into the survival thriller territory.

The pace is definitely on the slower side but I really liked the way it let us get to know the characters. We have a pretty diverse group of five people coming from different social classes, genders and races, and the author made me, in some capacity, care about all of them. Will’s depression and severe burnout after a life chasing a better social status. Elise and her shame about insulin injections in public. Tash, an outspoken trans woman just down on her luck. Senyo, a pragmatic Tube driver who loves his wife and nonbinary child with all he has. And Aaron, a perceptive young man whose kindness wasn’t beaten out of him by the life on the streets, no matter the odds.

Oh, Jonathan Sims knew what he was doing, giving us relatable and/or likable characters, especially Aaron and Senyo. I certainly didn’t go in expecting to encounter a pretty great found family aspect, but here we are! Frankly, if you don’t come to care about at least some of them, chances are you’ll get bored. There’s more introspection than action, which does sometimes result in losing that carefully built atmosphere, even for someone who actually cared.

Now, to the queer tag - yes. Some of the characters were queer, and I was hoping that would be it. Tash and Elise...entirely unnecessary, sprang on us simply because of a forced proximity situation with no chemistry whatsoever. I didn’t dislike them, not at all - it just made me tired. Please, you CAN write a book without adding some romantic sparks just to have that box checked, especially in the horror genre. I truly wish authors (and publishers, let’s be real) would realize that. It’s almost as if that potential for a future romantic relationship is supposed to make me care more about their survival? I guess I understand that logic but I also deeply dislike it for the implication that it makes them more worthy of rooting for.
To be clear, this is a very particular pet peeve of mine, not something that will affect most other readers, I reckon! ❤️

A cheeky question - how many horror/thriller media have you encountered where the characters got themselves into deep shit because they forgot to silence their phones? ...Yeah 😏

The actual rating is in the 3,5 ⭐ realm but I’m rounding up without hesitation because this book gave me Aaron to fawn over, and Senyo to wish I grew up with as a dad. And for that pretty great, satisfying epilogue!

Thank you to Poisoned Pen Press and NetGalley for the opportunity to read and review this e-ARC! The Burn Line is to be published on 25th August 2026.

i'm really struggling to rate & review this one... it's not bad at all, it just didn't blow me away either. i liked it enough to pick up something else from this author in the future though.

as a southern girl who often feels like her skin is melting off when she steps outside during the summer, i loved the setting of a stifling, claustrophobic underground London. the psychological horror elements are done really well & i think the author did a good job of adding his own fresh twist to the creatures here that most of us are familiar with. they're genuinely a little creepy. anytime i'm given a diverse cast that's always a plus too! (Tash was my favorite.)

where i get conflicted on the rating is the pacing & writing. parts one & five were the strongest sections of the book for me. the beginning has great tension, & the way the creatures are described immediately made me picture something similar to , which i LOVED. but the further i got into part two, the pacing started to drag for me & i had that issue until about halfway through part four. the writing was good overall, but it fell a little flat in certain areas.

the covid references were just really random to me, not because it makes the book feel dated or anything like that, i think with the news of the hantavirus it definitely feels more relevant BUT i just don't think it added anything to the plot? it never really tied into anything significant. it felt more like the author was mentioning covid just to mention it. i honestly kept forgetting the story was supposed to be set during covid & then a few chapters later there'd be another reference & i'd just be like "oh right..."

i’m not too into podcasts, but this definitely piqued my interest to check out The Magnus Archives, & i’ll definitely be checking out more books from this author.

‎ ‎ ‎ ‎The Burn Line follows a group of diverse characters who are all, in some way or another, down on their luck, living an unfulfilling existence or are in some way or another struggling under London's (metaphorical) thumb.

‎ ‎ ‎ ‎A dangerously hot heatwave is reigning over the city, reaching temperatures that would make it "illegal to transport cattle on the Central line because it was too hot." Unfortunately, there are no such regulations in place to protect humans, which is why we join our cast of characters in the London Underground.

‎ ‎ ‎ ‎Five strangers find themselves in a tube car, all for different reasons, yet with something pivotal in common. The travellers feel as if they just woke up from some type of dream. Dazed and unsure of how they found themselves where they are.
‎ ‎ ‎ ‎Traces of a mysterious, ashy, oily substance can be found on and around them, and a permeating, unpleasant sweet smell dominates the air alongside the heat.
‎ ‎ ‎ ‎It's confusing and unsettles them all. Whether they acknowledge or deny it, blame it on exhaustion or the heat, something horrible and life-changing has bound their fates together.

‎ ‎ ‎ ‎The group tries to leave what happened behind them, but the London Underground doesn't easily let go of what was once in its clutches...

⋆⁺₊⋆ ━━━━⊱༒︎ • ༒︎⊰━━━━ ⋆⁺₊⋆


What I liked/loved
‎ ‎ ‎ ✧ The set-up of the first chapter was an amazing introduction to the atmosphere of the story and offers vivid descriptions of the characters.
‎ ‎ ‎ ‎Before even a single sentence of dialogue is uttered, we already get some idea about who these completely different people are.
‎ ‎ ‎ ✧ The diversity. The characters we share a headspace with all come from different backgrounds, races, identities, and walks of life. Who they are as people, what their jobs are, their familial and non-familial relations, their ambitions, etc., all impact the way they experience and view the world. Which brings me to my next point.
‎ ‎ ‎ ✧ The multi-POVs worked really well. I loved that we got to experience characters we already knew through another character's perspective, putting them in a new context, getting to know them again through a different framing. We also got some overlap of POVs of the same events, which was fascinating to read.
‎ ‎ ‎ ‎I liked every character's POV I've read, but I loved spending time in Aaron's and Seyo's headspace the most.
‎ ‎ ‎ ✧ Amazing social and political commentary, which I can't really discuss truly in depth without spoilers, but just trust me when I say there is some interesting discourse.
‎ ‎ ‎ ‎Now, for those who have already read it: The Burn Line is very much a commentary on It's something very reflective of our current lived reality, which made it really easy to immerse and sympathise with the characters.
‎ ‎ ‎ ‎I specifically enjoyed the discourse on
‎ ‎ ‎I do think some exploration of those topics was a little on the nose, but I had a fun time regardless.
‎ ‎ ‎ ✧ Characters as commentary devices. It's narrative, it's character work, it's personal. This read is extremely character-driven.
‎ ‎ Our group is complex, flawed, and nuanced. Some I instantly loved, others surprised me by changing my opinion on them in ways I hadn't expected. Some made me roll my eyes or beg them to get that stick out of their arse. Their complexity makes them the perfect devices for exploring these social and political discourses on a personal level.
‎ ‎ ‎ ‎ ‎ ✵ Through Aaron, we explore altruism, empathy and kindness in situations that often force a person to grow hard and cold. Where selfishness is survival, yet not always the given choice.
‎ ‎ ‎ ‎ ‎ ✵ I love that we explore through Senyo how we sometimes have no choice but to be a part of a system we morally and fundamentally do not agree with. How being 'a part' of something is impactful in both negative and positive ways. That 'few against the many' goes both ways.
‎ ‎ ‎ ‎ ‎ ✵ Will was such a fascinating character to me. Someone complex, bursting with ambition and a certain desperation for success. Trying to win a game regardless of starting with an undeniable disadvantage. How something at some point has got to give.
‎ ‎ ‎ ‎ ‎ ✵ Through Elise, we explore what it's like to constantly have to make yourself palatable and presentable even when doing so is extremely exhausting.
‎ ‎ ‎ ‎ ‎ ✵ Tash takes us along the undesirable living situations she has to navigate and the unfortunate reality of having extra safety measures to think about when queer and/or trans.
‎ ‎ ‎ ‎Each character is in some way its own exploration of a corner of the social/political microcosm that makes up London, which mirrors worldwide circumstances.
‎ ‎ ‎ ✧ The first half of the book builds great suspense and has that "something is wrong, but I don't know what" feeling that keeps you engaged and turning another page.
‎ ‎ ‎ ✧ Though the disability/chronic illness aspect doesn't have a huge presence, I'm glad it was more than a footnote. It impacted Elise as a character, how she navigates the world and of course, her literal health and safety. I'm always thankful for non-lazy representation.
‎ ‎ ‎ ✧ There are lots of original takes on established horror tropes/themes/aspects. I love being surprised like that!
‎ ‎ ‎ ✧ Sims truly has a large vocabulary to invoke disgust with. Which is honestly really impressive. I don't think I've ever seen the word 'ooze' this much in one singular book.



What I didn't like/felt lacklustre about
‎ ‎ ‎ ✦ Though marketed as a horror, it wasn't really a horror to me. Yes, it was mysterious, dark, sometimes eerie, and it definitely contains some body horror, but I still wouldn't categorise it as such. Especially because a large part of the book was character-driven, mystery and at some point quite action-fueled. It feels like a genre-bend of multiple categories. So keep that in mind when deciding if this is the read for you.
‎ ‎ ‎ ✦ I did NOT care about the romance sub-plot. You can't just declare that there is a romantic relationship without anything to base it on. No scenes, no chemistry, nothing. We surely are told about it, but there is zero evidence that made me believe their "love".
‎ ‎ Not every book needs romance! If it doesn't add anything, just leave it out! This plot point truly was the embodiment of the phrase "yes, girl, give us nothing".
‎ ‎ I've noticed this with a lot of queer rep in books. When there is queer rep, there is often a romance dynamic to, I don't know, prove this queerness? It has a certain amatonormativity to it that I simply don't care for. I'd rather have single, well-developed queer characters than an empty romance plot just for the sake of it.
‎ ‎ ‎ ✦ There were some pacing issues.
‎ ‎ The first third of this book is all about mystery and suspense. This segment I loved.
‎ ‎ This is followed by a segment where some things are revealed, but not a lot happens. It felt a bit like waiting, which felt slow to me.
‎ ‎ The last third is almost survivalist, which I do enjoy, but it did become a little campy. There was somewhat of a different tone to the start of the book. Where it was once quite serious, introspective and deep, the third part became a bit more comedic and wacky. I didn't mind it, I had fun! But I did have to switch gears for a moment.
‎ ‎ ‎ ✦ SOLVED I have one question I don't have an answer to, and I'm not sure whether I missed it or if we are supposed to be left wondering. Either way, it is bothering me! If anyone knows who this is referring to, let me know:
I might just be a bit stupid, my brain may just be as cooked as the London Underground.



Conclusion/Notes
‎ ‎ I picked up The Burn Line just in time to fill that Summerween craving I've been having, and it definitely was a good snack for my growling stomach!

‎ ‎ The plot is original, fun and unique in its creature and worldbuilding, albeit a bit campy after a certain point. The suspense kept me on my toes, and I was genuinely invested in the survival of our main characters. Which I think showcases where this book shines: its characters.

‎ ‎ I loved meeting Elsie, Senyo, Tash, Will and Aaron, and to me personally, they were the showstealers of it all. They were layered, complex, messy, and sometimes made choices I did not agree with, but not once was I not invested in them.

‎ ‎ Overall, The Burn Line is a fun read. It wasn't life-changing, but it definitely made me feel less like shit about my own suffering of these ridiculously high temperatures, because the characters in this book definitely had a worse heatwave experience than I did. For that I am thankful!

The Burn Line is set to release on Aug 25 2026.

Claustrophobic, suffocating and gross. I loved this book so much! I absolutely cannot physically cope with hot and humid weather so this book constant reminders of the heat were almost scarier than the antagonist in this book. Seriously Sims did a banging job of conveying the oppressive nature of an extreme heat event. You know that heavy unrelenting sluggishness that settles in every part of your body and mind when the heat is unavoidable you can't escape it in this book.

I really liked the characters and how their relations evolved. They were about as random an assortment of people as you might find on the tube on any regular early morning trip. Regular people with regular struggles. Sometimes they had chemistry and sometimes it felt forced which felt real for a bunch of people who didn't pick each other but were forced to work together by circumstances.

If you're looking for more of the Magnus Archives, you might just be disappointed with this one. It's clearly the same author but it's definitely not more of the same. I also have to admit that some punches were pulled and that the pacing at the end of the book was a little off. If I hadn't been immensely taken by how Sims used the weather to set the scene those things might have affected my enjoyment of the book more.

Many thanks to the publisher and Netgalley for providing me an eARC of this book.

4.5 rounded up.

I was looking forward to reading this because I thought Sims’s “The Magnus Archives” was an absolutely amazing podcast for fans of horror; I was always impressed at how Sims kept up the level of quality over a large number of seasons.

This book’s tone reminded me of the podcast, but the podcast’s excellence lies as being part of a whole, I think (although there are some great standalone episodes) and maybe Sims’s fiction works better with n shorter form. I liked the individuals who were the main characters and I enjoyed the setting but I was not crazy about the big bad at all and the whole idea of them seemed a bit half-formed.

It wasn’t a bad read though and I would always read another Sims book based on the strength of “Archives.”

A group of strangers experience something mysterious on the London underground which they can’t explain. Suddenly events begin to happen that causes them to seek each other out.

Something is lurking in the depths of London and people are disappearing. The group begins to realize that they must take matters into their own hands.

Nicely developed characters that I’d love to meet again.

jonathan, why do you never read your audiobooks yourself, jonathan


something of a capitalist critique and the middle and lower class should work together to defeat the one true evil (aristocracy), some allusion to the billionaire who’s trying to never die by drinking his son’s blood, and a good old pandemic throwback - it’s delivering on themes but not particularly on a captivating reading experience

Review in the June 2026 issue of Library Journal

Three Words That Describe This Book: Multiple Points of view, Social Commentary, Horror-Mystery

Draft Review: Fans of the Magnus Archives podcast rejoice, its creator has written his first book, an entertaining and immersive eldritch horror-mystery set during a sweltering heat wave, featuring a monster in the London Underground. In consecutive chapters to open the novel, readers meet five strangers on a train car. One by one they tell their story of that fateful day as each experiences an unsettling moment of dissociation, notices a distinctly awful smell unlike any bad odor they have encountered on the Underground before, and comes away with a gray, flaky film clinging to them. The dread and unease from that fleeting moment follows each, first as a nagging bad feeling, then manifesting into a pale humanoid creature, stalking them. A story where every detail matters, bonkers in all the right ways, producing claustrophobic chills, and providing a biting social commentary, readers will dive into the tunnels and root for this motley group of former strangers turned found family as they work together to stop a terrifying monster and save the people of London (and themselves) from a terrible fate.

Verdict: With a huge built-in audience, libraries need to have this one available, but it is also an excellent suggestion for fans of Chuck Tingle, Alma Katsu’s Fiend, and Jeffrey Cranor and Joseph Fink’s Welcome to Night Vale.

Other words: Eldritch, found family. bonkers (but just the right amount, still serious horror), dark humor, stifling, claustrophobic immersive, popular podcast now writing a book, entertaining, terrifying, multiple points of view

First, it must be said that the author is the creator of the very popular original, horror-mystery podcast The Magnus Archives. It has a Welcome to Nightvale feel, but instead of a town it is focused on an archive and the supernatural mysteries that come from that.

So right away, you have an audience for this book at your library-- the millions of people who have enjoyed the podcast. Also fans of Welcome to Nightvale and its spin off books.

The story is original, entertaining, with an eldritch feel, and so stiflingly claustrophobic. We start on a London Underground car. It is the middle of the worst heat wave in London ever. This is important to the story because everyone is sweatier and more out of it than normal.

There are 6 people on the car. Part 1 of the novel is 5 of those people telling the story of their day on that train car. Elise (works for the transit ministry as a coder), Senyo (an Underground driver and union leader), Tash (an overnight hotel clerk), Will (a finance guy), and Aaron (young homeless man).

One by one they tell their story of that day. This is a great way to start the book because readers get to meet each character from inside their head. It sets up the fact that all 5 had a moment of dissociation on the train and that they knew something strange happened. They also note a strange bad smell-- very different from regular Underground smells and a weird flaky film that gets on them. The dread and unease from that experience followed them throughout their days and even moved into something stalking them (maybe) at home in their nights.

(Side note, I had two books with smell playing a big part in the story for this column-- Fabulous Bodies is the other)

And it increases the mystery around the 6th person. Which comes into play.

But the bouncing around of character helps to keep the story moving and allow the reader to understand the motivations of each character before they understand each other.

Here is the thing that Sims does well-- all the details matter. The five characters notice and work on things in their jobs, things that all get used in the story-- but not in a way that feels forced. I liked that. So for example, the heat wave and how and why the Underground is so hot and how people have been trying to fix that for years that comes into play. That is one example.

I always appreciate when the details that build characters and place also playing a role in the plot.

Like all good horror, the story is resolved but the chance of the monster coming back to find them is very possible. Sequel?

The social commentary about how hard it is to live in London with rising costs, racism, and how poorly the homeless are treated, and how the rich are getting richer, etc...it is all woven in to the story.

The monster deep in the tunnels is well built. It is more than they even realize at first and how they seek it all out and fight it is believable. Everyone uses the skills and professions they have to help solve the mystery. They really need to work together as a unit to save themselves from being the next victim. For example, Senyo has access to the Underground CCV for each car at anytime. Will has access to a very rich man who may know something about all of this. etc...

And in the process-- the found family they create is heartwarming. Even after the terror.

This is a solid, entertaining horror story with some social commentary. The mixture of dark humor with serious social issues and terror was done well, but it is a little over the top at times. That makes is a fun read and I cannot fault the author for that.

Paris nicely with Alma Katus's Fiend (ancient evil tied to the rich and social commentary) and Fabulous Bodies by Chuck Tingle (bonkers, smell plays a part, social commentary, mystery aspects) And of course fans of Welcome to Nightvale.

Just a hot day and your average day on the train - from work to home, home to work, each person on their own ride and in their own world. Until today - today, they all seem to wake up and shake off. . .something. They don't know what. There's only a few of them on this warm train and none of them know each other.

But as they each go home, they start hearing shuffles around them and something appears to be. . .stalking them. But as one of them has a friend go missing, assumed murdered, he knows he needs to find out who was on the train and they need to discover what is going on - before they all meet the same fate.

This was a great mystery that rolled right into a creepy horror story. I liked that we get each POV, each person waking up on the train and their movements from there. It really helped understand they all had their own lives that were disrupted by this moment. I liked how they came together, figured things out. I never guessed where the new shocking horror would pop up or how it would all come together.

I did an audio and the narrators were great - one of them being the author! It really did add to the urgency of the story and help discern each personality of the characters. A good story, I enjoyed it!

A huge thank you to the author and publisher for providing an e-ARC via Netgalley. This does not affect my opinion regarding the book.

Free digital copy provided for review purposes by Poisoned Pen Press.

I was drawn to this book because the concept of creepy happenings on London's tube network enticed me - there is an undeniable appeal to the dark tunnels and the upending of the mundane commute - so I was somewhat disappointed to find that setting quite loosely explored. Yes, the characters scramble through the underground for a bit, but the details of the environment and the inclusion of the trains themselves felt very sparse, and large swathes of the book take place away from the underground.

That might not be such an issue in itself, but there is an overall lack of detail and complexity that pervades this book and made it a disappointing read for me. We follow a fairly large group of characters, chapters switching perspectives between them, and because they are all written quite flatly (and share much of the same personality traits, reactions, and feelings), this feels like a structural decision employed to sidestep writing the real connective tissue of the story.

Very quickly, it all feels tiring. Just about every character expresses the exact same view of the world in the exact same way - we're miserable, we're poor, and we hate rich people - and it's just not very interesting. It starts to feel like characters are turning directly to me, the reader, to say, "I have the correct and moral view", which becomes even more tedious when the overarching message of the book is so transparently predictable because it precisely mirrors its identical protagonists' view of the world.

The fact that the one character who is some sort of middle class bridge between the working class characters and the cartoonish aristocratic ghoul types in lieu of exploring his character with any complexity for a second is frustrating. This moment felt emblematic of the book's total lack of interest in examining its characters or world beyond a Scooby Doo villain approach to class. And having just written that sentence - that makes it sound more fun that it is! I could imagine a simplistic, cartoonish exploration of class that worked better for just a touch more variance in its characters. But the rich people in the book keep saying "I am rich and sneering" and the non-rich people keep saying "this rich guy is sneering" and it's like, okay I got that. I understood that. I have received your signal.

There is a pervading sense of the repetitive, and the book's style feels remarkably young and simplistic, but it's the cartoonish, obvious, uncomplicated characters that primarily made the book a disappointment for me. The relationships they build with each other essentially happen while we're not looking, so they're broadly unsatisfying, but the larger issue is that these people just don't feel real. They don't feel distinguished, they have little to say, and they just parrot the same dull, basic political statements over and over again.

The characters feel flat, the political commentary feels stale, and the setting and the big bad of the book alike feel undefined, predictable, and boring.

It wasn't for me. Perhaps I am a ghoul.

I could easily see this being a Netflix series, and I think I would enjoy it more in a visual, episodic format. That gorgeous cover is cinematic in and of itself. I didn’t find it particularly scary or horrifying, I kept skimming to get to the action. Each character gets their own chapter and early on this set up felt very repetitive. We don’t need to see the story from every person’s viewpoint within it.

While I haven't read the author's previous novels, I am pretty familiar with his podcast, The Magnus Archives, which I enjoyed but did not love; at least not as much as many people seem to. Still, it's because of the podcast that I know just how well Sims can write horror (some episodes have stuck with me 5 years after the end of the show) but unfortunately this book fails to showcase much of the talent Sims has.

The premise is great: something is killing people on the Tube and a group of strangers has to band together to find out what it is and how to stop it. A bit simple maybe, but oftentimes in horror novels or movies things become too complicated so sometimes simple is best. The first chapter opens with a creepy, queasy feeling incredibly well... and then we have to re-hash the exact same thing happening 4 more times through every other main character's POV which takes up the entirety of the first section.

It's not until Part II where the plot honestly starts to kick in, which is about 20% into the novel and about 10% too late in my opinion. But now the plot is interesting enough that I'm captivated by it and am excited to see where it leads until I hit a wall at 60% when George comes into the picture.

The fact that everyone buys his story so readily is ridiculous because it sounds as if he's made it up on the spot, and yet the group goes along with it and decide to follow this man who they all privately don't trust into the depths of the Tube system to hopefully kill this creature that has been hunting them. Sure, I guess? Obviously they have to do something but going in on their own would have been better than this. I just don't understand how things got to this point when the middle bit was going so well.

The final battle ensues, Chekhov's insulin injection is used to keep some characters back to explore more, one of the worst one-liners I have ever read is used completely unironically, and at this point I have lost almost all interest I held in the book and I'm ready for the book to be over.

And it does end. Kind of. There's an epilogue where everything is wrapped neatly with a bow that doesn't feel particularly earned and that's it. Except also not because the threat is still very much there despite everything our heroes went through, so it felt like it was all for nothing. I can tell Sims was going for the found family trope here at the end, but again, it doesn't feel earned. We're told over and over again that certain people have become close in either romantic ways or not, but we don't ever really get to see that for ourselves, which is disappointing.

I think this would have worked better as a novella or a short story. Like I mentioned, for a good 40% of this book I was entirely locked in and eager to see how the story was going to progress, but then it went off the rails and not in a good/fun way. I also believe that having

The writing is done well, I appreciated the representation found throughout, and the concept is great, but unfortunately this book didn't work for me as much as I wanted it to.

This is a book that I'm rating solely based on its merit rather than a joint rating with my enjoyment because I read this while in a depressive episode. I'm quite familiar with Jonathan Sims and I was intrigued to see how a full length horror novel from him would go and I was not disappointed.

The book is very well written and there was a perfect balance of tension, suspense and the comedic moments in the novel. I liked the characters and how distinct they felt from each other, the different backgrounds they came from too. It was all very interesting to read about.

Can't quite say I was hooked from start to finish but even the slower moments did a good job of setting up the foundation for the faster paced moments. The ending was a bit anticlimactic but satisfactory nonetheless and that's a lot more than I can say for a lot of books I've enjoyed.

I have very mixed feelings about this book.

The premise immediately caught my attention. Five strangers experience something horrifying on a London Underground train, only to discover that they can't remember exactly what happened during those missing moments. When they realize whatever they encountered isn't done with them yet, they reluctantly join forces to uncover the truth before it finds them again.

I really liked the writing. Jonathan Sims does an excellent job creating atmosphere and I especially appreciated how vividly he captured the suffocating heat of the London Underground. Between the overcrowded trains, the relentless temperatures and the claustrophobic tunnels, I could almost feel myself sweating alongside the characters.

I also enjoyed the multiple POVs. Spending time with each of the five main characters gave the story a lot more depth and I found it easier to understand their motivations and connect with their individual struggles.

My biggest issue was the pacing.

For me, the first half felt like a very slow burn, so slow that I occasionally found myself waiting for something significant to happen. Once the story picked up, I was much more invested, but I do think it took a little too long to get there.

Overall, I enjoyed the atmosphere, the character work and the creeping sense of dread. I just wish the story had reached that intensity a little sooner.

⭐️⭐️⭐️✨

Review of advance copy received from NetGalley
July 31, 2026
A major letdown from a writer whose work just doesn't seem to translate from script to page. The Magnus Archives, a scifi/horror audio drama created by Sims, is up there with my favorite pieces of media of all time. This book has cemented my feeling that Sims' talent lies on two ends of a spectrum: short form stories, and longer, nested narratives. This book is neither. It is far too long, for one thing: clocking in at a whopping 384 pages for a plot that could have easily been communicated in a single 30 minute Magnus Archives podcast episode. There are large swathes of the book where pretty much nothing happens besides characters wandering around London, feeling unsettled, and engaging in increasingly complex metaphors about the awful ongoing heatwave. Approximately half of the internal monologues could have been cut to significant positive impact.

My other major issue is the disastrously poor execution of what could have been genuinely meaningful commentary on COVID-19 and class consciousness. The story as a whole is about as subtle as a sledgehammer, crafting pretty much every character and associated viewpoint with an almost anxious desire to broadcast the author's moral rightness on different issues (very Woke 1.0 if that makes sense to anyone). I feel strongly - and I feel this as both a queer person and an ardent social and economic leftist - that meaningful social critique in literature utterly loses its impact in the absence of subtlety & complexity. Every character in this story, POV or not, felt a like shallow caricatures, flat vessels for communicating the author's opinions on moral & social politics. This isn't totally uncommon, but occurred here to such a degree that I had to remind myself that these characters were NOT designed as bad caricatures in a terrible right-wing thriller. However, my issue goes deeper than merely observing a lack of realism. I find something coarse and infantilizing in this approach to representation: implying, perhaps unintentionally, that individuals with marginalized identities or specific progressive viewpoints cannot exist in a story as complex people: only as mouthpieces for ideas. None of the people we are meant to root for are "imperfect" in their progressivism: choosing the "morally correct" option on the dialogue tree at every impasse. This makes them tremendous fictional allies but poor legitimate representation: idealized copies of the real individuals they are meant to speak for.

TLDR, If this book was a Mass Effect playthrough, it would be a fully 100%ed Paragron run. Take from that what you will!

I'm going to start by saying that I had no clue who this author was. Apparently they have a lot of hardcore fans for their podcast and like a whole world built up that people are aware of in something called The Magnus Archives.

If you're like me and going into this completely oblivious to the above, I'm happy to tell you that this book was good!

I loved our characters. With all this death and destruction and the scary things that hunt them, I really wanted them each to find family and friends and their happy places. (I will not tell you if this happens or not.)

I found our premise very creepy and the truth behind everything very surprising and a bit epic in scope!

As for the ending, I was just a wee bit unsatisfied, but I really enjoyed the read and was thoroughly entertained.

The Burn Line is an unhinged novel set in London during a record breaking heatwave. And in the Tube, underground, something lurks. And it's very hungry. This is what six strangers find out as they're all riding the same carriage and are all in a daze for some reason. Something terrifying has happened, yet none of them have memories of it. But in the weeks to come, they are all being hunted by something. After a memory appears in one of them, they gather the rest to try and gigure out what's hunting them. Six strangers, all prey, and hardly an answer to be had. They'll have to fight together or risk getting picked off one by one.

The characters are what makes this book so interesting to me. These are six very different people yet they all have financial troubles and come from various backgrounds. Each section features chapters from each character's viewpoint and provides enough background on each one to give them time to shine. We have a homeless man, a hotel lobby clerk, an office worker, a financial trader, and a man who drives the trains underground.

This is also a nostalgic ode to the London which was, compared to the London which currently exists. As the author states at the end, he lived in London for twelve years and was happy for ten of those years. It's not a bitter mean spirited take on the big city though. If anything it's melancholy and a bit bittersweet. But the introspections of the characters exposes a wealth and class dynamic which we all see no matter where we live.

It's this backdrop which sets up the underground nicely. No spoilers, of course, but the creature isn't what you probably think it is, even when it's decided in a certain section that it is, indeed, what you think it is! But it's something much more terrifying and horrific and you won't see it coming. I highly recommend it.

"The Burn Line" was a struggle for me, and even days later after finishing it I'm still unsure why. I couldn't connect with the cast, I found the pacing uneven and often dragging, though there were scenes and twists I really enjoyed. But the overall result just wasn't compelling enough for me, and I often found myself putting the book aside. The premise is quite promising and entertaining, the author nailed it on atmosphere and setting, but why insist on repeating the same descriptions from different POVs, by characters with such uninteresting backstories? The ending was also a let down. In any case, I think readers who enjoy creature features will enjoy this one nevertheless, as long as they dive into it with the lowest of expectations.

Thank you to NetGalley and the publisher for this ARC!

This is a really good example of the kind of thing you can do with horror as a social commentary. More than anything, this book is a big, bundled class discussion and dissection, and the things that happen to the characters are in aid of that discussion.

The thing is, the characters are equally well fleshed out and developed, and so you get a delicious horror banquet that hits all the right notes in all the right places.

While we have five characters to follow, all of which are interesting but not overwhelming. All of them are well developed, and they don’t tend to take too much or too little of the narrative. I think my favourite characters were Elise and Aaron, just because they were so well written. The description of the public service was very apt, and I laughed more than once at some of the absurdity.

The monster threat in this was exceptional, and I think a really good twist on the normal lore. It just felt like it had a lot more work and care put into it, and I really appreciated it from a horror standpoint. The only thing I did feel could have been improved was the ending, but even that was only by a little bit.

The writing was exceptional too, and I think it’s definitely a testament to what horror should be- social commentary, a touch of wry humour, and, at the heart of it all, really good characters who make reading the book a delight.

3.5 stars rounded up to 4 stars

✨✨Atmospheric and tense, but a bit too slow at times✨✨

The Burn Line is a very atmospheric, creepy, and tense read! I really enjoyed it for the most part.

The setting of a stifling hot London Underground and 5 travelers trying to figure out what’s going on, why they can’t remember some stuff, and what is killing people was really intriguing. I definitely wanted to keep reading and figure it all out!!!

I did struggle with what to rate this one and that doesn’t happen to me often. Some of the pacing was a little off for me, it was really slow in some parts. The rest was pretty fast paced though and I did really like how well done the tension building is. I think maybe it was because of how many POVs there are why it was slow at times.

I’m pretty happy with the ending. As a whole, I really liked The Burn Line!

My Selling Pitch:
IT on the London tube.

Pre-reading:
Listened to a few episodes of The Magnus Archives tonight to prep for this. They’re quite good for horror short stories. They’re well-paced and genuinely made me feel uneasy. I really, really dig the anglerfish concept of the first story. A predator with a lure is gooooood. She spooky. Supposedly you can read the book independently of the podcast. Thank goodness because I don’t have a prayer of catching up. I’m bummed I’ll miss references though! (This book functions independently from The Magnus Archives.)

(obviously potential spoilers from here on)
Thick of it:
He is so good at breeding eeriness. We’re not even out of chapter one.

Is it not a cat? (Not a cat!)

I like the diversity, but I feel like the cast might be one member too big considering we basically had to repeat that train scene five times.

It’s a little Planet Midnight (my favorite episode of Doctor Who) and a little weeping angel because they forget them when they’re not looking at them.

OK, American Psycho. We love a nod to Patty B.

Count again, girlie. Someone got melted? Sludged? Eaten?

Kinda reminding me of Bat Eater with covid in the subway and the not so subtle digs at our governments being shitty to the common people.

So the monster’s Voldemort lol.

The way it paralyzes them reminds me of how scientists think dinosaurs like T. rex may have used low-frequency noises like gators make to stun their prey.

The visuals of this are so good, but now that we’ve seen the monster, I need it to pick up again. You killed that tension. You have to give me something to replace it. So like the pacing is kind of faltering for me.

This middle bit is DRAGGING.

It went from some threatening monster to some dude’s bitch ass daddy escaped the old folks’ home, and I no longer care to see it resolved. 🙄
Hopefully, there’s a further twist because there’s a lot of book left. The story’s kinda reminding me of IT where it was like omg how do you survive this to that’s it? 👀

I feel like they’re just gearing us up for some confrontation in the tunnel where they’re gonna drive a train at the thing, someone’s gonna have to hug the wall, and they’ll barely get a message out, and I just don’t care. (Missed opportunity much.)

I don’t like any of these characters.

I like the something’s coming poster. That was good. That was fun.

What is Delacey’s bag? Like he lying but for why? (For shits and gigs is BAD motive.)

I’ve hit bored.

I just- it’s very conspiracy theory ooo, the world is controlled by rich lizard people, and I’m bored.

They’re just overgrown subway rats.

I’m so checked out. I do not care.

Yeah, it’s so weird and rude of them to choose survival. Super crazy motive🙄

I dunno, if it’s an object permanence issue, have they tried ADHD meds😂 I mean, that is a kinda sorta speed. I’m just saying-

Shoot it through its mouth?

You had the opportunity for a funny ringtone joke, and you went with the default? Lame.

Don’t the police have dash cams though, so-?

Let’s go lesbians!

God save the queen 🫡

That’s it??? I feel like we didn’t even finish killing the monsters.

So you survive an evil brought on by the elite class, and you’re like you know what I’m gonna do with this money? Give it to the charities- you know, the ones run by the elite class.

Post-reading:
This was pretty disappointing. I really enjoyed the podcast episodes that I listened to before this which are basically just a collection of horror short stories. They’re notably open-ended. And I point that out because the setup for this novel is great, but the follow through is… Like homeboy can set a mood. The visuals are excellent. They’re very cinematic. He can get the hairs up on the back of your neck…as long as he’s relying on your brain to fill in the horrifying blanks. It’s such a common problem I have with horror where as soon as the author shows us the monster, the story loses all bite. It’s always scarier before the big reveal, so horror authors do have to walk a fine line between keeping an audience’s interest while not dragging it out for too long and showing their hands too early. This was way too early. We get the monsters pinned down and the threat of them neutered almost as quickly as they show up. Paralysis and the fact that the characters will forget the monsters if they’re not looking at them (which is a bit too Doctor Who to feel original) feel like valid threats until in the same breath they’re listing off the dangers, the characters have already figured out how to fight through them with sluggish movement and exposure therapy recall. And the balance never tips back to keep the tension. If you don’t up the ante or move the goalpost, all that hard earned dramatic pressure dissipates.

We have to slay the monster and survive is not enough to carry a story when you’ve already shown us they can be killed.

An interesting first third will not keep me from checking out in the back half when the story devolves into something familiar. This feels like yet another riff on IT. You’ve read this book before. We’ve got a ragtag group banding together to fight an impossible monster while we slowly reveal their tragic backstories.

And unfortunately, the backstories aren’t all that tragic. I didn’t care. I didn’t like any of the characters. They felt like pretty stock archetypes to rage against capitalism. And I’m down for some societal critique in my horror-in fact, I think it’s a MANDATED element of good horror. But you’ve gotta give me more than the blanket statement all rich people are evil. It reads like a bad conspiracy theory. The plot of this is essentially lizard people are running the government. That’s eyeroll worthy not satisfying, especially when we don’t even finish the hero’s journey. I’m all for take the money and run, but it feels like we just ended the story because we hit word count. They move away, end scene. There’s room left for a sequel and if it’s following IT so closely already, you’re kind of just like okay, when does the band get back together to storm London part deux? And it’s not in this book. I don’t think this needs a sequel. I don’t think there’s gonna be that sort of demand for it.

The book’s also painfully similar to Bat Eater, and I think that book does a whole lot more with less. Even though this book is really pushing its diversity, which we love to see, it doesn’t have anything unique to say about those perspectives. It’s kind of just listing them off. It feels a little performatively inclusive rather than own voices. Bat Eater is gonna give you something a little more culturally sensitive, you’re gonna care more about the characters and their possible deaths, and it’s got more of an activism arc than welp, the whole system’s corrupt, so we’re just gonna move away and leave it for someone else.

I don’t think the book as a whole is bad enough to go on my do not read list. I think it’s fine even if I wouldn’t personally recommend it. I think you can still read better. I would, however, actually recommend the podcast. I did enjoy those. I think if I heard rave reviews about another book, I would give this author another try, but from this sampling, it seems like he just puts a spin on other people‘s work that he’s enjoyed.

Thank you to NetGalley and Poisoned Pen Press for a copy of this e-ARC!

The Burn Line was my first exposure to Jonathan Sims and it is safe to say I believe that the hype is well deserved. This book was eerie, placing a new spin on a beloved horror trope of mine, vampires. Sims’ ability to produce dread is fantasy, the description of these monsters are revolting and nasty, the body horror was excellent when it became present.

However, the biggest gripe I had with this story was the character’s relationships. I enjoyed all of the individual characters from what we got of them, but I think this story would’ve benefited a lot more from either: a) being longer to show rather than tell the development between the cast, especially with the family dynamic. Yes, the situation is high stakes, and there’s a nasty white freak chasing them around; but, whenever the dynamics between the characters were mentioned I found myself wanting more out of it (ie Tash and Elise, Aaron and Senyo) or b) having the amount of POVs cut down to strengthen individual characterization, as I personally felt as though it felt spread thin.

I would have found myself rooting for them and their individual arcs a lot more if I were shown bonding rather than largely told about it. A lot of it seemed to have happened off page and that aspect disappointed me the most in this story, especially when it becomes so vital to the narrative later on.

“The plot is plotting” was essentially my reading experience for the first third of this book. And then, unfortunately, the plot finished plotting before the book finished being a book.

The Burn Line begins with a genuinely fun horror mystery: several strangers were together on the London Underground during an unexplained event, their memories are wrong, something smells sweet and rotten, people appear to be missing, and CCTV eventually reveals that there were seven passengers in the carriage when everyone remembers six. Excellent. I was IN. That mystery was carrying this book on its back like an exhausted single mother.

My biggest problem, however, appeared very early: despite having several POV characters with radically different lives, most of them sound surprisingly alike inside their own heads. They ask the same kinds of rhetorical questions, explain their fear in similar ways, make similar sensory comparisons, and repeatedly narrate their uncertainty instead of simply experiencing it. Different demographics and backstories do not automatically create different POV voices.

Aaron was the exception. His perspective actually felt shaped by homelessness, class, politics, and the way he reads other people socially. Senyo also had a strong emotional anchor through his family. Will eventually became interesting enough that I was genuinely annoyed when the book killed him, which is more than I can say for poor Elise, who spent most of the novel making me ask: girl, why are you here?

Elise has anxiety. She has diabetes. She loses her insulin exactly when the plot requires another complication. Tash falls in love with her at remarkable speed; despite being one of the central characters, Elise spends an astonishing amount of this book reacting while everyone else actually does things. At one point I started mentally checking whether she had completed her mandatory “be worried, have blood sugar problems, stand nearby” quota for the chapter.

Which brings me to the romance: Tash apparently loves Elise. Okay. When did we build this relationship? Where are the scenes that make me believe this? The book repeatedly tells me that their connection matters, but I rarely felt it developing on the page. By the time we get dramatic “I love you” internal monologue and kisses during the climax, my reaction was less “finally!” and more “oh, we’re doing this now?” Apparently emotional development was happening offscreen while I was busy reading about ghouls.

The prose also desperately needed someone standing behind it with scissors.

This book will stop an action scene to explain things you absolutely did not need explained. My personal breaking point was a climactic sequence where Tash is preparing to shoot someone and the narrative suddenly gives us a mini-history of Samsung’s “Over the Horizon” ringtone, including the Galaxy S2, remixes, and a comparison to the Nokia tune.

I am begging you: There are ghouls everywhere; someone has a shotgun and a man is about to get his head blown off. We do not need Samsung trivia right now. This is not the moment for Phone Ringtones: A Brief Cultural History.

The same problem affects the horror. The monsters initially work because they are strange, sensory, half-understood things connected to missing memories and unexplained disappearances. They feel uncanny because nobody quite knows what happened, what they saw, or why the evidence does not match their memories. Once the book reveals the underground nest and begins explaining exactly what these creatures are doing, the atmosphere starts turning into something closer to The Descent: Eat the Rich Edition™.

And yes, the class metaphor is intentional. Extremely intentional. Painfully intentional.

The ghouls are dead upper-class creatures who refuse to disappear, remain powerful by feeding on ordinary people, hoard wealth, and are protected by institutions and elites. I GET IT. The metaphor itself is not bad; horror has been using vampires, zombies, parasites, cannibals, and assorted undead rich people to talk about class exploitation for approximately forever. The problem is that the novel often seems terrified I might somehow miss the symbolism, so characters periodically stop to explain it to me as though I am attending a seminar called Monsters and Capitalism 101 and participation counts toward my grade.

By the final act, the mystery has largely transformed into running, fighting, shooting, body horror, betrayal, another betrayal, a ghoul queen, people getting badly injured, Will dying, Tash blowing Delacey’s head off, Delacey coming back as a ghoul, Elise finally doing something useful, and then—

Manchester. They leave London.

Aaron gets money from a stolen gold ingot. Senyo apparently folds Will’s mother into his family situation. Tash and Elise move north. Elise emails journalists, nobody replies, and the novel ends with her sitting in a job interview explaining why she left the Department for Transport after three weeks.

“Burnout.”

--THE END.

After an underground conspiracy involving aristocrats, government connections, monsters, disappearances, memory alteration, and what appears to be generations of institutional complicity.

Burnout. Okay. Yeah, whatever.

There are genuinely good ideas in The Burn Line. I liked the initial mystery a lot. Some of the creature imagery is wonderfully disgusting. Aaron was easily my favorite character, Senyo had enough emotional grounding to keep me invested, and the seventh-passenger CCTV reveal was probably the moment when I was most excited to see where the story was going.

Unfortunately, the book was much better at creating questions than answering them, and once the mystery became an action-survival plot, my interest dropped dramatically. The political metaphor became less metaphor and more PowerPoint presentation, the romance expected emotional investment it had not properly earned, and the prose kept explaining things long after I understood them.

This one took me longer to read than it should have. July was a very busy month in all the best ways. Between family vacation and everything else life decided to throw into the mix (life, am I right?), all that reading time I had planned never quite materialized.

And honestly, who knew 4-year-old boys cling to their moms more than dryer sheets cling to microfiber? 😂

Had I actually had the time, I probably would have finished this in a couple of days. I had a hard time putting it down, and when I did, it spent that time living rent-free in my head.

Jonathan Sims does a fantastic job of taking something that's been written a million times in a million different ways and somehow making it feel fresh. It's a vampire story (or is it? 👀), with a strong undercurrent of "the rich get richer while the poor suffer" woven throughout.

My only real downside was the pacing. The beginning felt a little slow, while the ending felt rushed. It almost felt like the book was originally much longer and then trimmed down, with most of the cuts coming from the final act.

While I completely understand that the character building at the beginning is vital to the story, I found myself wishing we'd gotten more of George. I also would have loved more backstory on the creatures. Combined with the rushed ending, it left me feeling like there were pieces of the story missing.

All in all, I'm giving this book 3 stars ⭐⭐⭐.

I enjoyed it, and I would absolutely recommend it to others. But for me personally, I just can't push it past that 3-star mark.

Obviously I'm here as a Magnus Archives fan, and I'm so thrilled to be so up to date that I got to read this before its pub date, but I'm also into horror anyways so I like to think I wasn't swayed too much by preconceived notions. Not sure that there has ever been a more timely book release as the UK succumbs to yet another heatwave, the pace of this story had a slow, simmering build that I really enjoyed. Sims' descriptions of the heat on the London Underground were replaying in my mind when I was there over the weekend and that wasn't even a horror element, just setting the scene.
I don't think this follows the found family trope in the standard way, but circumstances really do throw these characters together from all walks of life and require them to have each other's backs.
Overall, I wasn't blown away. I do think we've seen this style of Underground horror before, which is not to say that I didn't have a great time, the building of suspense was fantastic and each character's background was relevant to the unfolding story. And I loved the 'eat the rich' energy throughout!

3.5 overall!

I was intrigued by the cover alone with this one and was definitely excited to see what it had in store. I loved the multiple POV’s of each character and seeing each perspective and how they come together. You definitely get to feel for each character and the struggles that they go through. This was definitely a slow burn thriller and builds up the suspense.

I guess I was expecting something different with this book and did want more of the creature part of it. With the long chapters it did feel dragged out and long winded at times where there could’ve been more action. The twist also did feel predictable and I wanted just maybe a little more from the ending.

Overall, this one was middle of the road for me and was good at times but also a slow burn that I felt needed to speed up some.

I can't remember the last time a horror novel attacked my olfactory senses in such a way. I would literally smell the words coming off my Kindle. New fear unlocked being underground in a subway after reading this! I enjoyed the multiple POVs and how all the characters came to recall their shared horrific experience in slightly different ways. I thought the cast of characters was thoughtful and diverse, and the story would make for a great movie or limited run series.

Thank you to Poisoned Pen Press and NetGalley for the opportunity to read and review this ARC.

The London setting, in the underground tubes particularly, is a terrific choice. Instantly anxiety inducing, the hot dark tunnels can hide any sort of nastiness! Jonathan Sims plays on that fear and anxiety so well in this gripping read.
5 strangers experience something at the same time while riding the tube (subway for NA) yet can't really get a handle on what happened, especially since no one else remembers anything. As they slowly come together to unravel this mystery, they experience dark days and insane happenings. The sense of dread and tension is built slowly but surely, culminating in a great ending. With 5 main characters and a host of others, it gets busy keeping everyone straight but it's worth the effort.
Eerie and atmospheric, this engaging novel worked well for me. I would definitely read more from this author.
