Fleetwood Mac:Behind The Masks?

[The Chain]

So I have Mick Fleetwood's autobiograpghy, and Bob Brunning's The First 25 Years. I heard there is another Brunning book called Behind The Masks.... Is it about the actual BTM line-up? Or does it only a biography of the overall like in 25 years?

And I have not touched any Stevie Book, due to hearing poor reviews... But I am looking for Everything You Want To Know... I heard it was awsome, can anyone add?
