That was a great book! Both of them actually. I have a collection of his books. One of my favorites is "Just Like Jesus" that was the very first book I read by him. I find it hard to pick my favorite from him, I think they are all good!
Blue Like Jazz was awesome...I think a book that every Christian should read. It helped me a lot when I was doing ministry in an area very similar to where he was at (Reed College). Outside of a few points of weak theology (the whole thing on choosing), I found it right on. I also like the way he writes and tells stories. It was easy to get into, and one of those books you just wanna keep reading.
