'A Man in Full' and 'I am Charolette Simmons' are two of my favorites. I picked up 'Kingdom of Speech' last year, but couldn't get into it. The other two though will keep you up at night. Great writing.
I'm genuinely curious myself. What little I've read of it made it seem like a sensationalized account of how young women in college are imagined to behave, as per an out-of-touch old man.
He supposedly did a lot of research on just how the hook-up culture on campuses worked. (Don't mean that cynically or suggestively--just that he always worked hard for his source material.)
I read this while in college, and it was, well, horrible. The characters were terrible and unbelievable. Maybe 50 years on it will be something of a good intro to college life in the 2000s, but I disliked it.
