Law School Confidential was good. I saw it as pretty much as step-by-step description of what law school was like. This made the book give me some feeling of comfort and familiarity going into law school. There's also some very good advice that I probably wouldn't have thought of myself. It's not, however, the end-all, be-all of law school preparation in my mind. In fact, it doesn't really talk about pre-1L preparation, how to take exams, etc., just some ideas on how to brief.
In short: A good book to read to increase your comfort level/awareness in going to law school, but doesn't stand alone as a supurb preparation for law school book
