Kiandra has to use her wits and tech-savvy ways to help rescue Edwy, Enu, and the others from the clutches of the Enforcers in the thrilling final novel of the Children of Exile series from New York Times bestselling author, Margaret Peterson Haddix. Since the Enforcers raided Refuge City, Rosi, Edwy, and the others are captured and forced to work as slave labor on an alien planet, digging up strange pearls. Weak and hungry, none of them are certain they will make it out of this alive. But Edwy’s tech-savvy sister, Kiandra, has always been the one with all the answers, and so they turn to her. But Kiandra realizes that she can’t find her way out of this one on her own, and they all might need to rely on young Cana and her alien friend if they are going to survive.
