Slaughterhouse-Five or The Children’s Crusade: A Duty-Dance with Death is considered Vonnegut’s most influential work. Centering around the firebombing of Dresden, the work is partly autobiographical and follows Billy Pilgrim through World War II and time.
My books are being thrown out of school libraries all over the country—because they’re supposedly obscene. I’ve seen letters to small-town newspapers that put Slaughterhouse Five in the same class with Deep Throat and Hustler magazine. How could anybody masturbate to Slaughterhouse Five?

All I can say is, “Good luck to them, and good luck to the government, and good luck to God.”
