Joseph Gray was a child prodigy who grew up to be a Bill Gates-like mega-innovator (space travel, robots, computers, etc.) and multi-billionaire with big plans. One of his creations is an advanced neural net computer that may be independently intelligent but that may also be having psychological problems. Dr. Laura Aldridge, brilliant but controversial Harvard professor of psychology, is hired (one week for one million dollars!) to diagnose the computer. The action is fast paced, and the ideas are intelligent in this "cyberthriller". Definitely worth a read -- and there's a lot of it (657 pages).
