15 year-old Corriane Renaldi lives in a world no one ever wanted to see. Brutal attacks have left her country empty and almost uninhabitable. The only people she has contact with are the people who followed her and her father to an empty military base that they turn into a fortress, somewhere by the Great Lakes. Life is rather boring for her until a stranger comes to the base in the middle of the night, and changes her life forever. Corrie is forced to leave the base, her best friend Orrin and a ten year old bratty genius tagging along. They don't know what they are looking for, but they find way more than they wanted, and end up in the fight of their lives.
