The Emmy Award-nominated and Edgar Award-winning duo of Susan Kim and Laurence Klavan deliver a heart-pounding finale to the post-apocalyptic teen world of the Wasteland, filled with dramatic twists and turns. Bestselling author Karin Slaughter called the first book in the trilogy, Wasteland, "a Lord of the Flies for future generations. An irresistible page-turner." No one dares to leave the District—the towering structure of glass and steel that is their protection against the unruly bands of Outsiders that roam Mundreel and the deadly rain that carries the disease that kills everyone over the age of nineteen. This skyscraper stands amid the urban devastation, the city rumored to have once been called "Montreal." Esther and her allies have created a haven on the rooftop, a garden that flourishes, and a home for her new baby, hidden from all but the very few who know her secret. But as Gideon's power grows and factions form, the ultimate darkness is born from greed, and Esther must find a way to save the citizens from themselves.
