From the bestselling author of DARK MATTER and the Wayward Pines trilogy comes a relentless thriller about time, identity and memory --- his most mind-boggling, irresistible work to date, and the inspiration for Shondaland’s upcoming Netflix film.

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.
