High in his attic bedroom, twelve-year-old David mourns the death of his mother. He is angry and alone, with only the books on his shelf for company. But those books have begun to whisper to him in the darkness, and as he takes refuge in his imagination, he finds that reality and fantasy have begun to meld. While his family falls apart around him, David is violently propelled into a land that is a strange reflection of his own world, populated by heroes and monsters, and ruled over by a faded king who keeps his secrets in a mysterious book... The Book of Lost Things.
