Exo

Gr 7 Up—After becoming a colony of an alien race, Earth has seen peace for 100 years. When certain children reach age five or six, they receive an exocel, or hard alien skeleton fused into their bodies. Donovan, 17, is an exo, and his erze marking designates him as an enhanced human soldier, indoctrinated since age 12 into training for SecPac, the colony's security force. His human father is Prime Liaison, the lead diplomat between the human government and erze oversight in West America. A human revolutionary group called Sapience instigates hatred toward SecPac by encouraging people to kill anyone who is erze-marked. During a shoot-out with suspected Sapience members, Donovan is captured by the group. After being tortured, he expects to be executed, but he becomes Sapience's bargaining chip after they learn who his father is. Even as he realizes that his father is not willing to negotiate for his release, he falls for a young Sapience member, Anya. The fate of Earth rests on his survival because if Sapience kills him, it could spark another intergalactic war. Donovan discovers how his choices and actions can have devastating results, and his loyalties are torn among SecPac, his warring estranged parents, Sapience, and Anya. This action-packed novel asks readers to consider alien technology, what it means to be human or nonhuman, and the gray areas in war, where neither side is completely good or evil.
