In a future where most of the men are dead, Cole and her twelve-year-old son Miles are on the run from the most dangerous person she knows ... her sister. Miles is one of the lucky survivors of a global epidemic. But, in a world of women, that also makes him a hot commodity. The Department of Men wants to lock him away in quarantine, forever, maybe. A sinister cult of neon nuns wants to claim him for their own; the answer to their prayers. And boy traffickers are close on their heels, thanks to Billie, Cole's ruthless sister, who Cole thought she left for dead. In a desperate chase across a radically changed America, Cole will do whatever it takes to get Miles to safety. Because she's all he's got.
