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