One of the most useful graduate courses I took was called “Structure of the Novel.” So often, studying writing has to do not with learning something new but with heightening a conscious awareness of something you have previously registered only naturally and vaguely. “Structure of the Novel” was one such awareness-heightening course, and it comes to mind today because I have just finished reading a book with nearly unparalleled structural acrobatics: Faulkner’s Light in August.
