This isn't a review of Tom Wolfe's I Am Charlotte Simmons. I haven't read the book, and am not sure I have the stomach to. But I found Steve Garber's review (thanks to Tom Grosh) and it's well worth reading. It's a little long, so whet your appetite with his conversation with two young women about the book.
One of them found the story of Charlotte's freshman year at college to be frighteningly realistic, while the other recalled plenty of on-campus exceptions to the sex-drug-and-alcohol party crowd: first and second generation Americans, goal-driven students intent on getting into graduate school, people immersed in their field of study, and communities of faith.
I don't know about the book, but the review is simultaneously horrifying and hopeful.
