The theme of "The Luster of Lost Things" is seeking out one's inner truth in the urban, alienated world. The hero of the book is a young boy, Walter Lavender, whose speech disorder has rendered him incapable of communicating with other people, and has resulted in many limitations that he imposed upon himself. He sets off to accomplish a mission of finding a lost book from his mother's shop. This journey will set him free and teach him many hidden truths about himself and the world.
