People don’t disappear from airplanes—that’s impossible. That’s what sixteen-year-old Grace thought, until her mother vanished while flying home. Grace has no father, no brothers, and no sisters. But then Vivian, her mother’s sister, unexpectedly shows up—ready to take the girl in. Only why does she live in a secluded house in the forest and never invite guests? Why are there iron bars on the windows, a mountain of red shoes in the wardrobe room, and where does the aunt go at night? Locked doors that need to be opened. Mysterious creatures you’re going to meet. Magical riddles you’ll have to solve… Grace is ready for anything to find her mother. But is she ready to learn the truth about her family?
