Abbie Devereaux wakes in the dark. She is hooded and bound, with no idea where she is or how she got there. Kept alive by a man she never sees, his only promise is that eventually he will kill her - like the others.

But Abbie has spirit and bloody-mindedness on her side. She counts the seconds spent alone and plots her survival. Above all she dreams of returning to normal, careless, everyday life - the land of the living.

Grasping at memories, Abbie recalls snatches of her identity, her career, and her disintegrating relationship with her boyfriend. Is there a connection between her real life and the voice in the darkness? And how can she survive in a place where fear becomes madness and the effort to survive seems too much to bear?
