She wanted an adventure. She never imagined it would go this far.

It begins with a reality TV show. Twelve contestants are sent into the woods to face challenges that will test the limits of their endurance. While they are out there, something terrible happens—but how widespread is the destruction, and has it occurred naturally or is it man-made? Cut off from society, the contestants know nothing of it. When one of them—a young woman the show’s producers call Zoo—stumbles across the devastation, she can imagine only that it is part of the game.

Alone and disoriented, Zoo is heavy with doubt regarding the life—and husband—she left behind, but she refuses to quit. Staggering countless miles across unfamiliar territory, Zoo must summon all her survival skills—and learn new ones as she goes.

But as her emotional and physical reserves dwindle, she grasps that the real world might have been altered in terrifying ways—and her ability to parse the charade will be either her triumph or her undoing.
this was a hard book for me to get into....it got confusing going back and forth between the reality game and the current state of affairs. but I'm glad I stuck with it -- a good story.
