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 shockwave, unleashed by a stunning discovery – and what s in jeopardy is not just our minds.

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.

A fantastic read – Andy Weir, Number one New York Times bestselling author of The Martian
