Through strange metaphysical circumstances, failed screenwriter Brad Cohen finds himself caught in an infinite time loop, forced to relive the first forty years of his life again and again. Each "repeat," Brad wakes up in the womb on what was supposed to be his fortieth birthday, with full knowledge of what's come before. In various timelines, he becomes a successful political pundit, a game-show champion, a playboy, and a master manipulator of the stock market, but none of them seems to lead him out of his predicament.

This is the way the world ends: with a nanosecond of computer error in a Defense Department laboratory and a million casual contacts that form the links in a chain letter of death. And here is the bleak new world of the day after: a world stripped of its institutions and emptied of 99 percent of its people. A world in which a handful of panicky survivors choose sides - or are chosen.
