I came later to William Styron, only reading Sophie's Choice because it was on the Modern Library list. Styron's books appear on many other "Must Read" lists and have won several prizes.
Here is his bibliography, from oldest to most recent. Those I have read are in red; those on my TBR shelf are in blue.
Lie Down in Darkness
The Long March
Set This House on Fire
The Confessions of Nat Turner
In the Clap Shack
Sophie's Choice (reviewed here)
This Quiet Dust
Darkness Visible
A Tidewater Morning
Havanas in Camelot
