The Sirens of Titan

"Somebody up there likes me. Malachi Constant"

Oh no, they don't. In fact chances are that even if there were somebody or something up there, it's more than likely they don't care about you. At all.

Sirens of Titan (1959) was Kurt Vonnegut's second novel and is notable for being one of his more overt Science Fiction novels. Set in 22nd-century America, it tells the story of Malachi Constant, one of the richest men in the world, who has the gall, the temerity to attribute his good fortune to divine providence.

His life changes irrevocably when he encounters Winston Niles Rumfoord, a playboy millionaire turned space explorer turned omniscient being after he pilots his spaceship into a chrono-synclastic infundibulum. Rumfoord is effectively "smeared across time" and becomes aware of all events, past, present and future. Armed with this knowledge, Rumfoord begins to direct Constant on a quest of self-knowledge and instruction, along the way setting up the "Church of God the Utterly Indifferent".

This Book Contains Examples of the Following Tropes:

 * Assimilation Plot
 * Batman Gambit: Rumfoord effectively.
 * Black Comedy: Standard in a Vonnegut novel.
 * A God Am I: In a godless, indifferent universe, Winston Niles Rumfoord is the closest thing to a deity we have.
 * The Chessmaster: Winston Niles Rumfoord.
 * Cosmic Plaything
 * Have You Seen My God?: Missing, presumed non-existent.
 * Heel Face Turn:
 * Insignificant Little Blue Planet
 * The Man Behind the Man
 * Minovsky Physics: The chrono-synclastic infundibulum. Overlaps with It Runs on Nonsensoleum.
 * Political Correctness Gone Mad: The self-handicapping custom of Rumfoord's followers.
 * Shaggy Dog Story: The story may not be pointless, but.
 * Or at least, has been so far. There's a subtle implication that complete,  may signify the beginning of humanity's freedom to pursue our own destiny, for better or worse.
 * Shown Their Work: Parodied. Vonnegut states that all information pertaining to cosmic phenomena is quoted from a (fictional) children's encyclopedia.
 * Take That, Me!: The doctors in the Martian army will erase a person's memories if they're deemed to be unfit for duty. They don't erase everything, though, because when they first did that the patients "[C]ouldn't walk, couldn't talk, couldn't do anything. The only thing anybody could think of to do with them was to housebreak them, teach them a basic vocabulary of a thousand words, and give them jobs in military or industrial public relations." Before he decided to write for a living, Vonnegut was a public relations man for General Electric.
 * Together in Death: Subverted in Vonnegut's trademark gentle sardonicism.
 * Rich Idiot With No Day Job: Both Constant and Rumfoord qualify for this before their respective changes.
 * You Can't Fight Fate: Everything that Rumfoord predicts comes true.
