The Big U: A Hilarious Satire of American College Life
by Neal Stephenson
I read this the summer before college, when I was reading every college-related book I could get my hands on. That ended up being mostly Big U (giddy, dark, ridiculous, and hilarious) and Tom Wolfe's I Am Charlotte Simmons (his disdain for his own characters dripped off every word).
Both very useful in my college life. Definitely.
