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.
