Somewhere under Chicago there is a corridor that does not end, with a door every few feet, and the only difference between the world behind one door and the world behind the next is whatever is happening inside your own head when you reach for the handle. Think about your worst fear at the wrong moment and you will open onto it. Jason Dessen learns this in the dark, alone, with a drug wearing off and his pulse doing exactly what you would expect. That is the best idea in the book and Crouch does the right thing with it, which is to make Jason's emotional state a load-bearing part of the machine. You do not steer this thing with a dial. You steer it by managing your own panic. I have not stopped thinking about that corridor since.
Getting there takes a while, and the setup is doing more work than it looks like. Jason teaches undergraduate physics at a small Chicago college. Fifteen years ago he was on track for something much bigger, and then Daniela got pregnant, and he chose the marriage. He is fine. Mostly. He walks home from a bar one night where a friend has just collected a serious prize for the career Jason did not have, a masked man puts a gun on him, and asks whether he is happy with his life. It is a good question to be asked at gunpoint, and the answer Jason gives is more complicated than yes.
He wakes up in a version of the world where he made the other choice, and the man who put him there is himself. That is the engine. Crouch has built his career on premises that can be explained in one sentence at a party, and this is his cleanest one, because the science-fiction apparatus is bolted directly onto the most ordinary regret a person can have. Every set piece in the back half is really an argument about whether a life with a wife and a fifteen-year-old and a mortgage counts as a life you chose or a life that happened to you.
The prose is functional. Crouch writes in short present-tense bursts, sometimes down to two or three words, and if you want sentences to admire you are in the wrong hangar. It gets the job done at speed and occasionally it gets flat. The tour through alternate Chicagos in the middle also runs longer than the idea needs, with a couple of worlds that exist mainly to prove the mechanism still works. And Daniela, who is the entire prize the whole novel is competing for, stays thinner on the page than a character carrying that much weight should be. She is warm and she is real, but she is mostly seen.
Why you should read
- Great if Recursion's premise-first storytelling worked on you
- Speculative thrillers built on one clean rule
- Science fiction that stays domestic and personal
- Readers who found the book through the Apple TV+ series
What to expect
- Short present-tense chapters built for speed
- A slower first third before the machine opens
- Physics used as a lever rather than a lecture
- One late escalation that changes the whole book
None of that dented the last act for me. The escalation Crouch pulls in the final stretch is the one move that turns a good premise into a genuinely upsetting one, and I will not touch how it works, except to say that it takes the ordinary agony of the road not taken and multiplies it until the arithmetic becomes horrifying. What lingers afterward is not the physics at all. It is the image of a man standing in a corridor, trying to keep his mind steady enough to picture a kitchen, a wife, a kid at the table, because that picture is the only navigation system he has.
