I've been buying Heat every week for years, and I loved Smash Hits during his years as well, so I was interested to see Mark Frith had written this. He's a great magazine editor, but unfortunately that talent hasn't transferred to the writing of this book.
I agree with other reviewers that feel it is rushed. It seems like he wrote this in six months after he left Heat and his memory seems to fail him a lot. Stories are dealt with quickly. Stories that are covered in more detail, like the fall of Jade, which is one of the most interesting bits, only have a couple of pages devoted to them. Often a days diary entry is only a hundred words or so long and just states a big story that broke that day, e.g. Britney got married, with little other information such as his feelings on it. At one point he mentions a lunch with Simon Cowell and a few tidbits of information, I was dying to hear what he thought of Simon, but he never goes into any detail. Thats the thing, its very factual with little depth and I feel he holds a lot back.
My overall feeling is he's done it as a quick moneyspinner and thats a shame because it could have been much better.
