Christine McVie - born Christine Perfect - was the quintessentially English rock star, as both the backbone and the beating heart of Fleetwood Mac.

Straddling the band's incarnations to achieve global fame alongside Stevie Nicks, Mick Fleetwood, Lindsey Buckingham and John McVie, the classic line-up, she wrote and performed many of their greatest hits.

As famous for their occasionally life-threateningly decadent lifestyles as for their musical brilliance, they were held together by this strong, constant figure whom they dubbed 'the mother' of the band. It was Christine who contained the flock, regrouped them when they went AWOL, focused and blended their talents and always got them back on track.

And yet, as the 'engine' of the band during their Rumours era - an album which charted the complete romantic disintegration within the band - Christine's personal life was every bit as tempestuous as those of her bandmates, weathering affairs, divorce, addiction and fiery passion, all of which bled into her now iconic song-writing.

Told by an author who herself was friends with Christine, and with new contributions from those who knew her best, Perfect offers a true insider's view, and deep psychological insight into Christine as a both a woman and a musician - the first, the only, the ultimate picture of a rock legend and a national treasure.
