Thanks for the feedback everyone. I'll definitely be checking out some of these books.
One that I didn't see mentioned that I really enjoyed was the Patrick Roy book written by his father.
I just finished the Pat Burns biography. Not worth it. I'll start it's own thread tomorrow with the reasons why.
Also, I just saw this today (which made me want to come and post it here), but there's a guy who reviews hockey books.
