(In a terrifying new world, four girls must depend on one another if they want to survive.) Just when things have gotten kind of normal for Rosie,she finds herself running for her life~~again. Only this time she's stuck with her roommates from school: Louisa, who can be okay sometimes;Maddie, who can't stop complaining and Evelyn, the girl with a million conspiracy theories. If she weren't so scared,Rose would be totally annoyed. But one of Evelyn's theories was right: The boarding school the girls were sent to belongs to the Alliance, the wrong side of the War. Rosie has no choice but to run and no one to rely on but her new friends. Whether she likes it or not.
