Upgrade by Blake Crouch


“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?

Upgrade is set in the future, after “The Great Starvation” has killed two hundred million people. This famine was unintentionally caused by a genetic engineer. That engineer was Logan’s mother. She was a brilliant scientist, but her experiments had devastating consequences. Now, genetically modifying anything is a crime and Logan works for the Gene Protection Agency.

Logan is exposed to a gene modifying virus on the job, and starts to notice changes in his mind and body. He has become sharper than ever. He has better concentration, vision, and strength. With this new version of himself, Logan is the only one capable of saving humanity by stopping a plan that is already set in motion.

Action, drama, suspense, and science combine in this fast-paced technothriller.

I received a digital copy of this book from the publisher via NetGalley in exchange for an honest review.
