The world as it was has been all but destroyed. Those who survived the Great Ending are now ruled by an all-powerful group known as the Chosen. Desperate to repopulate, the Chosen send searchers to capture every surviving female still living in the wild lands beyond the city. A girl with a name neither of her companions can remember is found by the searchers living on a remote property. Since then, she has known little more than a life dominated by the Chosen's breeding program and genetic experimentation - while they immunise her and prepare to take her to their city. Then one afternoon a son of one of the Chosen arrives at the girl's farm - and his arrival sets in motion a chain of events which change the girl's life in ways she could not possibly have imagined - offering her a chance to regain the unthinkable - freedom.
