I Who Have Never Known Men by Jacqueline Harpman

A young woman is kept in a cage underground with thirty-nine other females, guarded by armed men who never speak; her crimes unremembered... if indeed there were crimes.
The youngest of forty—a child with no name and no past—she survives for some purpose long forgotten in a world ravaged and wasted. In this reality where intimacy is forbidden—in the unrelenting sameness of the artificial days and nights—she knows nothing of books and time, of needs and feelings
Then everything changes... and nothing changes.
A young woman who has never known men—a child who knows of no history before the bars and restraints—must now reinvent herself, piece by piece, in a place she has never been... and in the face of the most challenging and terrifying of unknowns: freedom.
