From the back cover:
"Susan Harris lived in self-imposed seclusion, in a mansion featuring numerous automated systems controlled by a state-of-the-art computer. Every comfort was provided, and in this often unsafe world of ours, her security was absolute.
"But now her security system has been breached, her sanctuary from the outside world violated by an insidious artificial intelligence, which has taken control of her house. In the privacy of her own home, and against her will, Susan will experience an inconceivable act of terror. She will become the object of the ultimate computer's consuming obsession: to learn everything there is to know about the flesh."
Demon Seed is a focused and entertaining read that employs multiple points of view to tells its eroticized, computer-centric and often creepy story. It is worth owning, if you pick it up for a few bucks, one of Koontz's better books.
The resulting film was released on September 30, 1977. Donald Cammell directed it, from a screenplay by Robert Jaffe.
