When sixteen-year-old Madeline suffers her first grand mal seizure, she finds herself in an unfamiliar reality, surrounded by strangers wearing familiar faces. Her best friend, Brandon, tells her that the world has fallen to chaos, the aftermath of World War III ten years ago. Madeline doesn't remember anything from this life- especially not the explosion four years ago that killed her parents and landed her in a coma, or the Lord Commander; a zealot leader of the Southern Territories now searching for her. Madeline barely has time to process everything before waking up to the life she's always known. As soon as she dismisses it all as a strange and vivid dream, she finds herself back there once more. Unsure if she's truly caught in the middle of a brewing rebellion, or teetering on the brink of insanity, she finds herself flipping between the two lives. Her heart becomes torn between two versions of the same boy and the lines between her realities begin to blur as she struggles to save her lives in both worlds.
