Guardians (Wasteland #3) by Susan Kim & Laurence Klavan
This heart-pounding final book in the Wasteland trilogy is filled with dramatic twists and turns!
No one dares 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 all 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, an unlikely leader learns to control every action of the District’s people. As the ultimate darkness is born from greed, Esther must find a way to save the citizens from themselves.
