The world has ended... What comes next? Smallpox epidemics, floods, droughts—for sixteen-year old Lucy, the end of the world came and went, stealing with it everyone she ever loved. Even the landscape of her beloved New York City is ever-shifting and full of hidden dangers. As the weather rages out of control, she survives alone in the wilds of Central Park, hunting and foraging for food and making do with the little she has, while avoiding roving scavengers and thieves. But when an unrelenting pack of vicious hounds begins to hunt her, Lucy is not sure she can continue on her own. Then, suddenly, she is swept to safety by a mysterious boy named Aidan, who helps her escape the hounds and urgers her to join a band of survivors. Reluctantly, she finds him after her home is destroyed; however, new dangers await her. An army of Sweepers terrorizes the camp, carting off innocent people and infecting them with the plague. Lucy and Aidan realize that it's up to them to save their friends, but Lucy doesn't know that the Sweepers have laid a trap—for her. There is something special about Lucy, and the Sweepers will stop at nothing to have her in their clutches. Jo Treggiari spins a thrilling tale of adventure, romance, and one girl's unyielding courage through the darkest of nightmares.
