RECURSION - Ballantine

NAMED ONE OF THE BEST BOOKS OF THE YEAR BY Time ? NPR ? BookRiot

Reality is broken.

At first, it looks like a disease. An epidemic that spreads through no known means, driving its victims mad with memories of a life they never lived. But the force that's sweeping the world is no pathogen. It's just the first shock wave, unleashed by a stunning discovery?and what's in jeopardy is not our minds but the very fabric of time itself.

In New York City, Detective Barry Sutton is closing in on the truth?and in a remote laboratory, neuroscientist Helena Smith is unaware that she alone holds the key to this mystery . . . and the tools for fighting back.

Together, Barry and Helena will have to confront their enemy?before they, and the world, are trapped in a loop of ever-growing chaos.
