I enjoyed Light in August much more than As I Lay Dying and The Sound and the Fury, both which I had read in college. I did not know if that is because Light in August is the more accessible of these three Faulkner novels, or if I am just a better reader than I was 20 years ago.
So I reread The Sound and the Fury this year (see here) to make an adult comparison. It is a masterpiece, that's for sure. But my personal preference is still for Light in August.
