The book tells the story of Black Sabbath in the words of over 350 fans. Starting with memories from their earliest pre-Sabbath shows as Earth in the North West of England, the book charts Sabbath's gigging history through the drug-fuelled Seventies and a relentless touring schedule on the back of the classic first six albums that cast the die for heavy metal, fronted by legendary singer Ozzy Osbourne and backed by Tony Iommi, Geezer Butler and Bill Ward. Encompassing numerous line up changes in the years since, including vocalists Ronnie James Dio, Tony Martin, Ray Gillen and Ian Gillan, this is a fan's eye view of how Black Sabbath went on to become the greatest metal band of all time, selling over 70 million records worldwide.

Told from the perspective of fans the book includes personal photographs, memorabilia, anecdotes and stories that have never been published before.
