The Sirens of Titan was perhaps the novel that began the Vonnegut phenomenon with readers. It takes place at a time in the future, when "only the human soul remained terra incognita ... the Nightmare Ages, falling roughly, give or take a few years, between the Second World War and the Third Great Depression." The villainous and super rich Malachi Constant is offered a chance to journey into the far reaches of outer space, to eventually live on the planet Titan surrounded by three beautiful sirens.
