A dying assassin is given one last assignment and one last chance for survival. The job: to find God Almighty and destroy Him. The payment: eternal life. With the aid of a beautiful lady gambler, an ancient Hollywood witch, and a telepathic smartass of a girl, Dell Ammo breaches the gates of Heaven and Hell to pull the Cosmic Trigger.

Self-consciously styled after a hard-boiled detective novel, this is a most unusual and entertaining work of satirical SF. An assassin by trade, Dell Ammo works in a bombed-out section of Los Angeles that has been irradiated by a nuclear explosion. Terminally ill, Ammo is offered immortality by a millionaire evangelist if he will do one job: kill God. Accepting the assignment, Ammo embarks on a bizarre hunt through postnuclear L.A., assisted by Ann Perrine, a woman claiming to be an accountant but whose skills are considerably more interesting, and a nymphet with powerful, sexually telepathic abilities. In his search for God, Ammo encounters a powerful group of clerics eager to protect God, the source of their power, whether he exists or not. In other hands this could be pretentiously silly, but Koman carries it off with wit and energy.
