Kurt Vonnegut’s Slaughterhouse 5 is at once startlingly gritty and wildly sci-fi. Somehow it is both a critical response to the wartime atrocity of Dresden’s bombing, and also a trippy, ironic, even disturbing thought-experiment about the nature of nonlinear time. Originally published in 1969, Slaughterhouse 5 looks back at the end of WWII’s European conflict from the perspective of a handful of American prisoners of war held in Dresden (in slaughterhouse building 5 or, in German, Sclachthof-funf).
