Light in August

I think I have to give up on Light in August.  Too many variations on "He knew x but didn't know that he knew it."  It felt sharp the first time, even the second time, but by the tenth/twentieth (before I'm 1/3 of the way through the novel) it feels like a verbal tic.  I may yet try Sound and the Fury or Absalom, Absalom, which are usually considered his best work.
