Some places earn their bad reputation through tall tales or chance. Grizzly Falls is different. Here, killers aren't just the stuff of legends and campfire lore. Someone is in the nighttime shadows, watching the local teens play around in the moonlit woods. Waiting for the right moment, the right victim. Waiting to take away a life. Detective Regan Pescoli is counting the days until her maternity leave. Exhausted and emotional, the last thing she needs is another suspected serial killer.

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.
