The Sirens of Titan by Kurt Vonnegut
The Sirens of Titan is an outrageous romp through space, time, and morality. The richest, most depraved man on Earth, Malachi Constant, is offered a chance to take a space journey to distant worlds with a beautiful woman at his side. Of course there’s a catch to the invitation–and a prophetic vision about the purpose of human life that only Vonnegut has the courage to tell. From the Trade Paperback edition.
