Recursion

Recall creates reality.

As he looks into the devasting phenomena known as False Memory Syndrome—a mystery illness that drives its sufferers insane with recollections of a life they never lived—New York City police officer Barry Sutton is discovering just that.

Neuroscientist Helena Smith thinks that. She has devoted her whole life to developing technology that will enable us to save our most priceless memories because of this. Everyone will be able to relive their first kiss, a child's birth, or their last moment with a dying parent if she is successful.

When Barry pursues the truth, he confronts a foe deadlier than any illness—a force that targets not merely our thoughts but also the fabric of history itself. And only he and Helena together will have a chance to stop it as its repercussions start to unravel the world as we know it.

But with reality itself changing and collapsing all around them, how can they stand?

Recursion is a science-fiction puzzlebox about time, identity, and memory that is both a furious page-turner and a complex thriller as only Blake Crouch could have imagined it to be. It is also his most ambitious, thought-provoking, and captivating work to date.
