New Book: Gold Dust Woman, A Biography Of Stevie Nicks. Due Oct. '14

[Christopher]

This will undoubtably be the best biography (by a mile) we've ever gotten about Stevie Nicks - and that's not saying much compared with what's currently available. Though there was the paperback "Everything You Want to Know About Stevie Nicks" by Ed Ochs & Ethlie Ann Vare in 1984 which was a real page turner.
I'm most interested to know if it's unauthorized, or perhaps Stevie allowed access to her peers and collaborators, and maybe even sat down herself with Stephen Davis.
