All Violet wants is to keep her sister safe from the war; that's why she unwillingly became a spy for Dreamer Island in the first place. But when she's kidnapped and injected with a new type of magic, her whole world seems to descend into chaos. As much as she tries to stay focused on her mission, she quickly finds out that there are others like her, and those people have been assigned the task of stopping the war. Joining the five other magic users, called Mist Walkers, she travels, trains, and fights against the Red Queen's army with her new friends...but everyone has their secrets, and Violet is no exception. She wants her new friends to trust her, but revealing her job as a spy would threaten her sister's safety. Can Violet keep her sister safe and still keep her friends?
