The Cloud is an exhilarating, cutting-edge thriller from Pulitzer Prize winner and New York Times technology and science reporter Matt Richtel.

A late-night accident on a San Francisco subway platform has altered Nat Idle's reality. But then, there are no accidents.

Disoriented and bloodied after a near-deadly fall onto the subway tracks, freelance journalist Nat Idle discovers that a beautiful stranger has come to his aid . . . and that the burly man who barreled into him had intended to do Nat harm. What he doesn't know is why--and his quest for answers leads him to uncover a handful of mysterious deaths, and a bizarre neurological disorder plaguing Bay Area children . . . as he ventures ultimately into the Cloud.

In a brave new world, the Cloud is where we store data, secrets, dreams. But it is something more--something insidious with the power to change not just how we interact with the world, but our behavior, and brains? Nat, in search of the truth, finds himself lost in a psychedelic maze, discovering things that cannot possibly be, realizing there is no one and nothing he can trust . . . not even his own mind.

In the tradition of Lisa Gardner, Steve Berry, and Joseph Finder, Richtel has delivered a whip-smart page-turner that melds cutting-edge science with a technological mystery and a shocking finale. A deftly told tale, the scariest part of The Cloud is how close to reality it could be.
