NEW YORK TIMES BESTSELLER • “If Michael Crichton had written a superhero novel, it would look a lot like Upgrade.”—The New York Times Book Review

ONE OF THE BEST BOOKS OF THE YEAR: Time, She Reads

The mind-blowing new thriller from the New York Times bestselling author of Dark Matter and Recursion—currently in development as a motion picture at Steven Spielberg's Amblin Partners


“You are the next step in human evolution.”

At first, Logan Ramsay isn’t sure if anything’s different. He just feels a little . . . sharper. Better able to concentrate. Better at multitasking. Reading a bit faster, memorizing better, needing less sleep.

But before long, he can’t deny it: Something’s happening to his brain. To his body. He’s starting to see the world, and those around him—even those he loves most—in whole new ways.

The truth is, Logan’s genome has been hacked. And there’s a reason he’s been targeted for this upgrade. A reason that goes back decades to the darkest part of his past, and a horrific family legacy.

Worse still, what’s happening to him is just the first step in a much larger plan, one that will inflict the same changes on humanity at large—at a terrifying cost.

Because of his new abilities, Logan’s the one person in the world capable of stopping what’s been set in motion. But to have a chance at winning this war, he’ll have to become something other than himself. Maybe even something other than human.

And even as he’s fighting, he can’t help wondering: what if humanity’s only hope for a future really does lie in engineering our own evolution?

Intimate in scale yet epic in scope, Upgrade is an intricately plotted, lightning-fast tale that charts one man’s thrilling transformation, even as it asks us to ponder the limits of our humanity—and our boundless potential.

Five amazing stars!

Get ready for one of the best books you are going to read this year. It has been a long time since I have read a book that totally captivated me from start to finish but this one did it. We have Logan Ramsey a agent for a, not so distant future, government agency called GPA: A small agency created to fight against gene editing. He has his perfect family with a wife and daughter he loves. Then one day on a SWAT raid against a possible gene editing lab he is accidently? injected with a virus which starts to modify his genetic structure.

And for the better. Everything about him from mental to physical aspects gets enhanced. He starts to get stronger and smarter right before our eyes. And its totally fascinating. Especially when the bullets start flying! And the twists were genuine WTF moments.

This book was beautifully paced and written. From the pace, to the science which was mind blowing but not overbearing. And more importantly the overall emotional impact of the book.... We feel for Logan and his family and what he has to go through is not only suspenseful but soul crushing at times.

Just so hard to explain the book without spoilers but just know it's a great science thriller. This is my first book by Blake Crouch but it definitely won't be the last as I will fast track all his books to my TBR. If I had any complaint with the book is that it started to slow down towards the end but only briefly as it picked up steam again.

Once again, I don't really give out five start reviews so easily but this book was so entertaining on every level that it is well deserved. Now we just have to wait for the Netflix or HBO series which I hope gives it justice.

Book given free for honest review.

another thrilling read by crouch. preferred dark matter and recursion to this one, but still had s lot of fun reading this. lord of family drama and action and suspense to keep me wanting to turn the page. sometimes it gets too science-y for me, but dug all the balancing of ethics and humanity in the face of near future degradation.

Blake Crouch is in my top 10 of favorite authors but this book just fell flat for me. Uninteresting characters, a story that I had to force myself to push through, and and overwhelming feeling of describing this book as "smart man writes book to convince others he knows things." Very mediocre and entirely skippable if you're a Blake Crouch fan.

A short fun read with a similar trying-to-put-the-genie-back-in-the-bottle plot to the author's other recent releases. I found the final resolution more satisfying than I expected.
