Faulkner's 'As I Lay Dying' had an immense effect on me, and most of my novels bear the burn marks of this experience, those short chapters with their conflicting points of view, truth expressed by multiple perspectives. The other attractive thing about 'As I Lay Dying' was the way it gave rich voices to the poor.
When we have a favorite writer, it's always the places where they grew up, lived, worked, and that they recreated on the page that we most want to visit and commune with. Faulkner's Mississippi, Raymond Chandler's Los Angeles, etc. The mind of the reader longs to be somewhere, not just anywhere, and certainly not nowhere.
