Thank you to Netgalley for providing me with an arc in exchange for an honest review.

This was a very strange book. I'm not really sure if I feel satisfied with it. I also did not like the main character. I know sometimes it works for a story. But I guess I wasn't sold on it.

Tamsin Rivers, researcher at Myrica Dynamic, knows it’s bad when when she discovers her basement is sinking much faster than the city of San Siroco. It’s even worse when she discovers a door appearing out of no where in her basement.

A door is bad enough, but when an exact copy of herself steps out, that’s when things start getting really strange. Where did the double come from? Does it have anything to do with the experiments in underground data and communication transfer Tamsin and her team have been working on? Why does Tamsin start losing her memory?

Last to Leave the Room is a quiet horror novel. Starting with an underlying feeling of uneasy, the terror builds slowly, focusing mostly on psychological and body horror.

I liked that we stayed in Tamsin’s POV the entire time as it gave it the claustrophobic feeling the novel needed. It was easy to feel her fear and dread and to sympathize with her, despite her being a pretty unlikeable character.

I’ve never read a plot quite like this before, something I appreciate especially in science fiction. It brought up lots of interesting themes such as what makes a person unique, how much of a person is their memories and the danger of a thirst for knowledge.

The last part of the book was the weakest for me. Some of the more interesting plot points were glossed over, and that was disappointing.

I’d recommend Last to Leave the Room if you enjoy psychological horror with sci-fi elements. I’m looking forward to seeing what this author writes next!

Last to Leave the Room by Catlin Starling is a fun, psychological thriller perfect for the start of spooky season! It starts slowly but soon grabs you and won't let go. The story revolves around Dr. Tamsin Rivers, a tough-as-nails scientist working for a larger corporation. Her team discovers their city is slowly sinking, and Dr. Rivers finds her basement subsiding even faster than the rest. Things get weird when a door suddenly appears in her basement, and a doppelganger of Dr. Rivers walks out of it. Starling has again written a thriller that keeps you on the edge of your seat!

Thank you to St. Martin’s Press and NetGalley for the eARC of this book.

Last to Leave the Room was one of those "exercise in patience" books.

I loved Caitlin Starling's The Death of Jane Lawrence for it's beautiful writing and immersive atmosphere. And while that lovely writing was present here, there isn't much else for me to recommend, unfortunately. It's definitely a subjective miss for me.

I'll say up front--the excitement of this book really doesn't pick up until you're about three quarters of the way through, and it's fairly good. But if I were simply reading for pleasure, I would have quit about 10% of the way in. I was hoping for horror, or at least some dystopian thriller from the premise, but this is a lot of science fiction--and it's dry at that. Not only did I find myself lost half the time (with echoes of Howard Wolowitz yelling "I have a Masters Degree!" in my head), but there's nothing to really care about here. I want an emotional connection to my stories--it's what disaster films like Volcano, The Day After Tomorrow, and Armageddon have in common and did well. But it's entirely missing here. Who cares that San Siroco is sinking? Why is it? What's/who's in danger and how? We're told a couple times that pipes will burst or something, but nothing felt immediate, there was no sense of urgency. Nor is there any sense of answers or closure as to why any of this was happening.

And the characters themselves were nothing to sympathize with either. Tamsin's a horrible person with no connections but a cat, Lachlan is this sort of cyborg-ish super human that we're given no insight into and everyone else is just a flat Mr. this or Mr. that.

I can't say that I would recommend this book to anyone other than those looking for some slow burn speculative fiction. If you can push through most of the book, the last quarter is pretty interesting, but I wouldn't usually wait that long.

Very appreciative to St. Martin's Press for the invitation to read a copy of this ARC in exchange for a review through NetGalley.

This book did not go where I expected it to, and that's what I liked about it. Dr. Tamsin Rivers is working on what she assumes will be the discovery that makes her career, helped along by the not particularly ethical but very well-funded corporation. She can sense her research coming into sight; she can feel it just outside of her reach, like a door she can't quite open. Unfortunately, the city of San Siroco, site of her research, is developing an odd phenomenon. It's sinking, stretching downward, and her apartment building is sinking even faster (there's a wonderfully tactile description of the feeling of walking down the ever-more distant treads of the stairs). Even more unfortunately, that's not the only side effect. This does not of course keep Tamsin away from any mysterious doors.

For a book that centers on the kind of expansion that's hard to pin down (but is slowly causing harm), the story feels surprisingly claustrophobic. In tone, it reminded me of Sarah Waters's The Little Stranger, with a scientist/doctor narrator who's a little too caught in their own experiments and not alarmed by a little human damage as the measurements continue to be made.

I found it tense and engaging, and when I finished, I was very glad to go outside and find the world measuring exactly as I expected.

Thanks to the publisher, the author, and Netgalley for my e-arc in exchange for an honest review.

As I said in my initial Goodreads review, this book was an absolute mindf*ck and I loved it. Dr. Tamsin Rivers is investigating the distortions taking place in the city when a mysterious door suddenly appears in her basement. Then a double of her appears through the door. Then a double of her cat appears through the door. Then she wakes up one morning and thinks that SHE’S the double and her dimensional double has assumed her life as Tamsin continues to lose her mermories. Her “handler” comes and gets her, her mind starts getting right, and then a door appears in the handler’s apartment. And a double comes out of it. And then Tamsin kills that double, but then she’s worried that in doing so she has accidentally also killed the handler because she’s been reading a bunch of stories about how doppelgangers are inextricably linked. Eventually she shoves her double back through the door, the door disappears, things go back to sort of normal as they deal with cleaning up the repercussions on the city (including collapsed buildings, etc.) The Last to Leave the Room delves into themes that I absolutely love exploring, like what it means to be human and the ethics of experimentation. Plus, it’s super weird, and who doesn’t love that?

I devoured this book; it's a perfect read for spooky season and just the type of horror I like (creepy, atmospheric, without relying on gore and cheap thrills). The main character Dr. Tamsin Rivers is brilliant, put together, and decidedly not a nice person - in short, she’s one of my favorite types of characters (what can I say, I like my women with a side of sociopathy). At least, she's all those things until her doppelgänger shows up in her basement.

Watching Tamsin deal with this arrival of another her, going from self possessed and in control, to slowly losing her grip on reality and becoming more and more of an unreliable narrator, is a tension filled delight. Caitlin Starling excels at dropping clues that barely register at first until they become glaringly obvious, leading to a point where I sat up and cackled “oh sh*t” in delight.

Everything is told from Tamsin’s POV, and while there are several side characters, she and her dopp are the primary characters. But there's also her corporate-provided “minder” Lachlan, who is ever present in Tamsin's mind even when she's not there physically. I enjoy reading cipher characters like Lachlan, and the evolving ways we as a reader see her through Tamsin’s changing mental states. However we don’t really get to learn too much about her which is a shame as she’s fascinating in her own way. There is however lots of tension (sexual, romantic, and fear-based) between Tamsin and Lachlan, not necessarily healthy in how we see it play out (in the romantic sense) but very fitting with the story.

What didn't work for me was some of the explanation towards the end, which I found a bit unsatisfying but readers who like more of an ambiguous story may not mind.

"But maybe observing does produce the result observed; maybe if nothing had been measuring depth at the construction sites, not only would they have not noticed for months or years, maybe there would have been nothing to notice.
If she hadn't been going down to her basement, maybe the door would never have appeared."

Dr. Tamsin Rivers is a scientist. She works in a lap for Myrica and studies things underground. Apparently the city is sinking, which undeniably, is a problem. However, what is also troubling is that the basement in Dr. Rivers' home appears to be stretching. What is the correlation and why are these things happening?

Starling's books are each so different and interesting and science-y with interesting horror elements. Last to Leave the Room felt very science fiction/Twilight Zone-ish, and although those things aren't necessarily things I gravitate to, I did enjoy this one once it got going. I will say that it took awhile to get there though, and I was getting pretty restless until the a door appeared in the basement and Dr. Rivers doppelganger walked in. At that point I was like WTF, and tore through the book to see where it was going.

This would be a great book club book because there are so many interesting questions to be asked about the story and the science and the ethics and all kinds of things. Definitely a book I could see myself rereading in the future.

In Last to Leave the Room by Caitlin Starling, the city of San Siroco is sinking. The basement of Dr. Tamsin Rivers, head researcher investigating the subsidence problem, is sinking even faster. One evening, a door appears on the basement wall that wasn’t there before, and out of it walks an exact copy of Tamsin. Who is this second Tamsin? Where did she come from? How did she get here? And how can Tamsin stop the subsidence from destroying the city?

What I love about Starling’s style of horror is how psychological and character driven it is, and Last to Leave the Room is no different. Dr. Tamsin Rivers is, I believe intentionally, unlikeable as a character, narcissistic and self-serving and cruel. But Tamsin is, at her core, a scientist, and her obsession with the subsidence felt infectious. I appreciated the care Starling took to develop Tamsin’s character and show the research process, with Tamsin hyper-focusing on meticulously collecting data and measuring the progress of the sinking. I loved the way that Starling seeded doubt about whether Tamsin was a reliable narrator, allowing the reader to wonder what was real and what was an invention of Tamsin’s mind. While I eventually grew to sympathize with Tamsin, I loved Lachlan’s character even more. She is tough and intimidating, but her job as company muscle was portrayed in what felt like a realistic way, with excellent disability representation.

Overall I enjoyed this book, and at about the halfway mark it gripped me so tightly that I could not put it down until I finished reading it. I rated it four stars because I was left wanting a little more from the ending. The resolution seemed rushed, and I am left with so many unanswered questions. However, I grew to love the characters, and it was great to be back in another unsettling world of Starling’s creation.

Thank you to NetGalley and St. Martin's Press for gifting me a copy of this eARC!

I loved The Death of Jane Lawrence. And I’m happy to say the same about her upcoming title.
Immediately after reading the description I knew I had to read it.
Last to Leave the Room by Caitlin Starling is a story that will grab the reader from the first page and continues to build more intrigue and suspense up to the last page.
Last to Leave the Room is well written and is an absolutely riveting book.
The narration was tense throughout and it had to me on the edge of my seat biting my nails and staying awake late at night to find out what happened next.
This is the best kind of horror! And I ate it the hell up.

This was a weird book...

Dr. Tamsin Rivers is doing some secretive science work when title becomes clear that the city she lives in is sinking. Which on its own is an issue because she might be responsible for it. But her attention is drawn away onto her basement that is also sinking and the door that has mysteriously appeared there. And then a woman comes out the door throwing her life into complete chaos. The woman looks just like her thinks like her and seems to be her. As the doppelgänger becomes more like her Tamsin starts to lose herself more and more...

To be honest I only wanted to read this book because it’s the pick for a book box I’m subscribed to. Without that factor I wouldn’t have been interested in this book at all. Horror? Suspense? Thriller? It was none of those...it was basically a whole lot of nothing happening. Throughout the whole book we are trapped inside Tamsin’s head as she seems to be losing her mind. 90% of the book takes place in her house with just Tamsin and Prime (the doppelgänger). It would have actually been more interesting if none of it was real. As for the mystery? It’s never really explained why the door appears or if other doubles come out of other doors (there’s only one situation where this even comes up). The nature of her work is never explained... there’s just a whole lot of nothing.

So if you want to be bored and observe to a very unlikable person with zero redeeming qualities slowly lose her mind and her whole sense of self then do read this book. Just beware that nothing happens and anything that might have been interesting is just casually brushed aside. Lachlan though was an interesting person and I would love her story, it would be way more entertaining I imagine than anything to do with Tamsin.

I wanted to like this but it was boring which sucks because weird can be fun or at least interesting this was weird and boring. A boring book with a wasted premise. Before this book I never heard of the author not certain I am curious enough to read her other work... but I wouldn’t rule it out so maybe I’ll try something else.

4.5 Yes yes yes! Deliciously weird and trippy. Dr. Rivers is doing some shady work at her company’s underground node labs when her team notices some strange phenomena. We soon find out that these strange distortions are also happening in Dr. Rivers’ basement. So begins the unraveling of our main character and everything she thinks she knows about herself.

The tension was immaculate, Mx. Woodfield was a great addition, and the blend of tech and speculative was perfect. Things just keep getting stranger and stranger until it all comes to a head. I didn’t want to put this book down!!

Firstly, my thanks to Netgalley and the publisher for allowing me to read this book in advance of publication. My comments and opinions are my own.

"Behind her there's a soft click.
She glances over her shoulder. The door is open, just a little, maybe two inches wide. Beyond it is the abyss, exactly as she pictured it, exactly as she remembers it. It spills from the doorway like a substance, not an absence. It washes over the basement floor, lapping at the table legs, covering her notes. The lights cannot pierce it and are swallowed in turn.
The line of the dark rises."

Starling's latest book is science fiction horror, with light romantic elements. It's a specialty in the author's cook book of recipes, last seen by me in The Luminous Dead. In this latest novel, quantum physicist Dr. Tamsin Rivers is leading a research team assigned to find the source of the subsidence of an entire city. The city is literally sinking, at a uniformly even rate, with the potential to cause enormous destruction. But Tamsin has bigger problems, because she's discovered that her basement is also sinking, much faster than the city. And there's a mysterious door in her basement, one that seems to generate doubles. Doppelgängers. Or maybe not.

I enjoyed many parts of this book - it nails several scenes that are nail-biting and full of existential dread of the unknown. The switching of original and double is subtle and smart, and it left this reader looking for clues and tells to figure out who was real and who was not. And after a while, I was left wondering if both Tamsins were real, just from different worlds connected by the basement door.

I also enjoyed the character dynamics, particularly with the handler Lachlan Woodfield, with her tailored black suits and slicked back hair, and her unusual physique. The personality switches between Tamsin and Prime and Naught were also really well done. There were some areas towards the middle of the book that seemed to drag on, but I figured that might just be a byproduct of the distortion field that Tamsin was researching. (Ahem.)

Overall, I enjoyed this read, and am grateful for the opportunity. For a sci-fi thriller, it hit all of the marks.

"She lingers on a story: the devil teaches black magic to seven pupils in Salamanca, Spain. The last student to leave each night forfeits their soul. But one clever man argues that, when he leaves at sunrise, it will be his shadow that is last to leave the room."

I struggled through this one. This was my first book by the author so the writing style was a bit different for me. Once I got into though, I was REALLY able to get into it. But like I said, it did take me a while to get into the story.

The Death of Jane Lawrence was one of the first horror books I ever got into, and as such had landed Caitlin Starling on my radar for their ability to create an ambience of unease without relying completely on shock value. This novel is no different. Pulling on themes of identity, obsession, and ego: Last to Leave the Room manages to take a horror archetype and adjust it for a more modern reader.
Examining classic horror narratives in any media, the idea of the mad scientist has permeated the most commonly known examples since Mary Shelley’s Frankenstein. What quantifies this paradigm is not only a presence of morally questionable science, but an obsession with it. In that regard, Last to Leave the Room plays intentionally with this trope and subsequently evolves it to a more modern understanding. Horror is meant to reflect society’s fears, and while a crazy man playing god in a castle may be outdated now, what isn’t is the level of obsession depicted, and that is exactly what this novel is about. An unhealthy obsession that mutates and consumes the protagonist’s entire world, but mostly her identity.
If our sense of self is reliant only on perception, physicality, self appointment, and social achievement; if those elements are no longer unique to us, how do we then set ourselves apart from others? What makes us so sure we are who we think we are? These are questions posed by this book.
Ultimately, Last to Leave the Room is an ambient, creepy, mysterious dive into the unknown lead by a character made up of all those traits you don’t like about yourself. As such, I wholly recommend it, especially if you are looking for something to get you in the mood for spooky season.

An odd mash up of sci fi and horror and it was a miss for me. I was a big fan of the Luminous Dead which was more about the characters than the techno-horror stuff- this is the reverse. Tamsin must find out why her city is sinking and stop it. She finds an odd door and discovers she has a doppleganger who can do some of her work. Okay, fine but I got lost early on and was unable to rally. Thanks to Netgalley for the ARC. Over to others.

Absolutely fantastic! I couldn’t put this book down, I read it in a day. Twisted and disturbing, the reader doesn’t know who to trust. The author delivers a well written and compelling story. Highly recommend!!

Last to Leave the Room follows Dr. Tamsin Rivers as she and her team try to find out why the city of San Siroco is sinking. She finds a door that didn’t exist before in her own sinking basement, and one night, her double walks out of it. At first, it’s perfectly nice, but as time goes on, the double becomes more cold and calculating, and Tamsin is slowly losing herself.

Overall, I enjoyed this one. I grabbed it because it was narrated by @xesands, and I was not disappointed! Excellent audio-ing as always.

It’s listed as horror, but despite a couple of cringey body things, I’d say it’s more of a slow burn sci-fi. The emphasis is on the characters, which is always my favorite part anyway. I’m not sure I would have enjoyed it quite as much in print, but that’s down to Sands’ narration. Definitely recommend for some thoughtful, speculative SFF.

I received an ARC from NetGalley in exchange for an honest review.

I really liked Starling's debut, The Luminous Dead, thought Yellow Jessamine was decent, and didn't finish The Death of Jane Lawrence. Unfortunately, Last to Leave the Room was another DNF. Starling always has interesting, creepy concepts but she's also really experimental, which can be hit or miss. LtLtR just had too much going on. Pair that with characters I just didn't connect with, and I lost interest pretty quickly.

Doppelgangers, distortions, and doors: Dr. Tasmin Rivers meets her double, finds inexplicable spacial anomalies (the kind that defy the laws of physics), and encounters a new, sealed portal in her basement. Are these related to her subterranean research, or is it something more personal?

I found myself either skipping or rushing through narrative that tried to explain the distortions and subsidence occurring under the city. The story begins to flow at about 75% into the book (which is about the time I stopped reading for comprehension, and started to invest emotionally into Dr. Rivers). For someone who cares to see if there is logic behind the descriptions and explanations, these sections might be fascinating. I enjoyed the concept of duality in this book which brought to min Robert Louis Stevenson’s The Strange Case of Dr. Jekyll and Mr. Hyde.

I would like to thank NetGalley and St. Martin’s Press for the opportunity to read and review this novel.
