I just finished reading this book. I never followed Matusow or really cared one way or another, but when I was at the WSOP, they had an autograph signing for the book, so I figured for $25, it might be interesting.
I thought it was pretty good - a little too much of the hand history stuff in the latter half, but still really good. It seemed pretty honestly written, and it was a nice break from strategy books, but still relating to poker.
