According to Daniels, the book takes an in depth at the band's history from their formation through their first two studio albums, "Iron Maiden" and "Killers" featuring Paul Di'Anno on lead vocals and the first two albums featuring Bruce Dickinson on lead vocals, "Number of the Beast" and "Piece of Mind."

Daniels says that he wanted "to give a balanced and objective view on the first eight years. Two albums with one singer (Paul Di'Anno), two with the other (Bruce Dickinson)".

While researching for the book, Daniels spoke to many people that have been associated with the band including former members Dennis Stratton and Tony Moore, as well as fan club chief Keith Wilfort.

According to Amazon, the book also includes a foreword by current Guns N' Roses guitarist Ron 'Bumblefoot' Thal and an afterword from former Judas Priest frontman Tim 'Ripper' Owens.

This isn't the first time that Daniels has published a book at Iron Maiden. In 2012 Voyageur Press released his acclaimed illustrated coffee table style hard cover "Iron Maiden: The Ultimate Unauthorized History Of The Beast".
