The ultimate feminist dystopian novel.

Discover the haunting, heartbreaking post-apocalyptic tale of female friendship and intimacy set in a deserted world.

Deep underground, thirty-nine women live imprisoned in a cage. Watched over by guards, these women have no memory of how they got there, no notion of time, and only vague recollections of their lives before. As the burn of electric light merges day into night and numberless years pass, a young girl - the fortieth prisoner - sits alone and outcast in the corner. But soon she will show herself to be the key to the others' escape and survival in the strange world that awaits them above.
