The Heroin Diaries: A Year in the Life of a Shattered Rock Star - Nikki Sixx
Being a lover of memoirs and Motley Crue I had to read this.

There are diary entries written by Nikki Sixx during 1986-87 as well comments from people who knew him then. Motley Crue was big during that time so it's interesting to have a behind the scenes look at how he felt about being a rockstar.
