When twelve-year-old Leo Gable steps into his hall closet and falls through a tear in reality, he finds himself trapped in an endless obsidian corridor stalked by shadowy creatures called Collectors. With a head start from a surprisingly sympathetic Collector who was once a lost boy himself, Leo races through a dimension of impossible doors and cruel tricks. He meets Maya, his next-door neighbor, and together they discover that escape requires breaking through the floor itself. A story about loss, courage, and the strange connections that form when you're truly lost.
