The History of Luminous Motion (original 1989; edition 1996)

Amazon.com Amazon.com Review (ISBN 0394578759, Hardcover)

Phillip is eight years old. He experiences material reality as a hindrance, so he tries to stay in an inner realm composed only of abstract concepts like gravity, motion, sound and light. He lives with Mom, who stays alone in her bedroom. Once he killed a man with gleaming tools from a hardware store. He has a friend with whom he does burglary and drugs and seances. Then Dad comes to stay, and Phillip descends to a subterranean otherworld where he makes contact with "dead black things, obloid and featureless, like faintly disembodied laundry hampers." A sad, beautiful book.
