Slaughterhouse-Five is a novel by Kurt Vonnegut, published in 1969, that blends elements of science fiction with historical narrative, particularly the bombing of Dresden during World War II. The story follows Billy Pilgrim, an American soldier who becomes 'unstuck in time' and experiences moments from his life non-linearly, highlighting themes of fatalism, free will, and the absurdity of war within the framework of postmodern literature.
