Cat’s Cradle by Kurt Vonnegut
This is one of two novels by Kurt Vonnegut that I read recently for my book club (The Mules). It would probably be indexed under “science fiction,” but it reads as a somewhat superficial but funny satire of science, technology, religion, and the arms race. Like Vonnegut’s Slaughterhouse-Five, it is a triumph of dark humor, mixing irony and parody with a compelling plot.
