Kingsblood royal.

I had an English teacher in high school who spoke highly of this book in the late 60's, explaining that it was far ahead of its time in understanding race relations and anticipating their deterioration. I read it years afterward and agreed with her entirely. Lewis, who understood and portrayed the shallow materialism of American culture, also had insights into racial problems, which are sharply dramatized in Kingsblood Royal. There is fine use of irony throughout, starting from the title.
