Faulkner disappears into so many voices, it's just amazing. Light in August is violent, gritty, caustic (sometimes), and substantial. Its scope of meaty topics is very broad (racism, puritanism, nationalism, alienation) despite circling the events in one small Southern town, told from multiple perspectives, all presented sympathetically and invisibly. You never see Faulkner behind the words, even with the third person narration. That seems a tough trick to me.
