Fleetwood Mac: The Definitive History?

[SortaSavageLike]

Was on my way out the door at Barnes & Noble today when I came across a new large-format hardcover book titled (I think) Fleetwood Mac: The Definitive History, that I'd never heard anyone mention before. I didn't have time to stop and look, but the cover picture was that famous White Album group picture with John sitting down with a cigarette dangling from his mouth, and Stevie in her top hat looking stoned out of her mind. I haven't heard anyone mention such a book in the works these last few months, and I'm wondering if it's even an authorized work.

Ahh, here it is:

Eagerly awaiting everyone on this forum tearing it to shreds for flimsily-supported conjecture and chronological goofs!
