This book by Tom Wolfe follows Charlotte Simmons as she encounters college life at Dupont U, a fictional highly-selective college. Charlotte is from a small town in western North Carolina, and she's impossibly brilliant.
She is, unfortunately, not brilliant enough to detect that she's the main character in a Tom Wolfe novel, which means that she's going to get the rug pulled out from under her life, and we get to watch. She finds herself interacting with three fellow students: Jojo, a fading basketball jock; Adam, a dorky Jew from Boston; and Hoyt, a devious fratweasel. Charlotte also has a rich-bitch roommate, and a couple of girlfriends that she bonds with out of their common loneliness. We also catch amusing portraits of a can't-get-over-the-sixties professor, the powerful and manipulative basketball coach, and many others.
In short, it's a lot of fun; but as the father of two kids in college, I couldn't read it without wincing a lot too.
