Dark Matter: A Novel

By Blake Crouch

“Are you happy with your life?”
 
Those are the last words Jason Dessen hears before the masked abductor knocks him unconscious.
 
Before he awakens to find himself strapped to a gurney, surrounded by strangers in hazmat suits.
 
Before a man Jason’s never met smiles down at him and says, “Welcome back, my friend.” 
 
In this world he’s woken up to, Jason’s life is not the one he knows. His wife is not his wife. His son was never born. And Jason is not an ordinary college physics professor, but a celebrated genius who has achieved something remarkable. Something impossible.
 
Is it this world or the other that’s the dream? And even if the home he remembers is real, how can Jason possibly make it back to the family he loves? The answers lie in a journey more wondrous and horrifying than anything he could’ve imagined—one that will force him to confront the darkest parts of himself even as he battles a terrifying, seemingly unbeatable foe.
 
Dark Matter is a brilliantly plotted tale that is at once sweeping and intimate, mind-bendingly strange and profoundly human—a relentlessly surprising science-fiction thriller about choices, paths not taken, and how far we’ll go to claim the lives we dream of.

Dark Matter follows Jason Dessen, a physics professor whose quiet life shatters when he’s abducted and wakes up in a reality that isn’t his own. He soon realizes he’s been thrust into a multiverse where every choice creates a different version of his life. As Jason races through alternate worlds, he confronts who he could have been and what truly matters to him. At its core, the story is a fast-paced, mind-bending thriller about identity, love, and the cost of choosing one life over infinite possibilities. THIS BOOK COMPLETELY SURPRISED ME. I remember last year @ellishartauthor posted about this book in his stories saying it was one of his favorite books and I’ve had it on my TBR ever since. I finally read it and am so pleased to report this book is in fact, amazing. I’ve always thought about infinite timelines and how there are possibly countless versions of us, each shaped by a single decision, a missed turn, a moment of courage or fear and how in each timeline, we’re living with the consequences without ever knowing the alternatives. The idea that somewhere, another version of you chose differently has always fascinated me, so reading a book that actually plays out that concept was incredibly satisfying. What I loved most is that beneath the science and chaos, this story is a love story at its core: grounded, emotional, and human. Across every timeline and every version of life, there is only one true love, and that truth felt both comforting and devastating in the best way.

I loved the style that this book was written in. Contrary to some of other reviews I thought it was different and enjoyed the pauses as they give you time to catch your breath and absorb everything that happens. Time to let you mind play with the ideas and the possibilities; but, I like different. I like weird. I like having my mind tickled by a great story and good author. A mind-bending, gripping read that keeps you turning pages. This one had me reading until 2 AM and I'm excited to see how this translates to film.

My first Blake Crouch read. Loved the book; great writing and excellent storytelling. The rating could have been even higher, but I found myself too frustrated with the main character taking so very long to realize his initial situation. This became a significant distraction until the 42% mark where he finally figures it out and we can start enjoying the story.

This book is an unexpected and exciting adventure through time and space. It provokes intrigue and curiosity about how worlds can be different with just one small change as well as how people become different humans with completely different personalities with just one different decision. The story is enticing all the way through and you simply want more when it's finished.
