Southern Reading Challenge Books

Well, all three of my book choices for the Southern Reading challenge have arrived and I'd really like to start all three but I must finish rereading The Highest Tide by Jim Lynch as the book discussion is Monday. I'm also continuing to read and enjoy The Silent Spring by Rachel Carson. I'm not sure which of my souther books I will start. I'm tempted to start with As I Lay Dying by Faulkner as technically it is probably the "hardest" read.
