Slaughterhouse-Five or The Children's Crusade: A Duty-Dance With Death by Kurt Vonnegut, Jr. (1969)

This is a novel everyone should read, both because of its cultural significance and its (so-called) literary worth. I found it confusing and jumbled until I realized that Vonnegut had deliberately written in the style of one from Tralfamadore, no beginning, no end, everything told at once. Long classed as a work of science fiction (because of time travel and, of course, the Tralfamadorians), Slaughterhouse-Five is less sci-fi and more a literary look at death and perception.
