The Purloined Boy, by C. R. Wiley, is a work of fantasy literature for young adults. In parts dark and grotesque, in others luminous and inspiring; it could be described as R. L. Stine meets Plato. It begins with the question, Where do all those children on the milk cartons go? It provides the answer through the eyes of one of those children, a boy named Trevor Upjohn, the purloined boy.
