Just finished the audio book of his "Into the Void".
Very entertaining. I am very anti drugs but if I had had his life (very up and down with various band members in and out/changing bands etc etc ) I may well have done drugs myself!
I particularly loved the beginning when he mentions his family growing up, and of course his time (s) with Ozzy Osbourne.
Not a book if you hate the music I guess but if you do you will probably enjoy it. I also loved towards the end where he talks about life with his wife and family.
