Cat’s Cradle by Kurt Vonnegut.Read about the other entries on the list.
Like [The Chrysalids author John] Wyndham, Vonnegut went back to the apocalyptic well many times. Cat’s Cradle is an early work, but it stands out as a masterpiece because of the astonishing virtuosity of its storytelling and the sneaky indirections of its plot. We know the world is going to end, we just don’t know exactly how or when, and the book jeeps us waiting all the way to an insane, bravura climax. Also, if you read this book you’ll be exposed to the teachings of Bokonon. Wampeters, foma and granfalloons will change your life.
Cat’s Cradle is one of David Peterson's five best books with invented languages.
