Twelve-year-olds Hazel Brown and Alina are separated one afternoon after Alina gets taken to a fantasy realm. Here, she has to throw away what she thought she knew—just to start over again. She is told stories about her past and is now instructed to juggle two things: to help her city and to decide where she really belongs. Then, when things finally start to turn right side up again, she realizes her own weight is too heavy to hold. She has to quickly save the city before it is destroyed and choose her own destiny... but alone. Is she enough to solve both problems, or will her heart and city crumble before she even gets to know her real last name?
