But when she starts flashing between realities during the day and seeing people disappear before her very eyes, she can't deny that something is happening to her—something she's sure is linked to her mother's disappearance. Then the unsettling Kai Awana shows up at school, and Lali discovers she has inherited her mother's ability to astral project—with a surprising twist. Not only that, but Kai needs her help to get to a world she never knew existed. In exchange, Kai promises to help Lali find her mom using his own unique ability. Now Lali must learn to control her budding power if she ever hopes to see her mother again. She's not sure she can trust Kai, but with her mother's life hanging in the balance, will she have a choice?
