As for the story itself, there isn't much of one. Most of the book is an expose of the extremes and abuses of the show. Star judges fight with one another for better contracts. Staff are treated like dirt. The protagonist, Sasha King, is called "Bill" by cast and crew alike. Bill was her predecessor's name, and no one can be bothered to learn a new one. Just in case anyone didn't already think so, this book will make it clear that Idol is full of egotism and excess.
As mentioned, there's no real story. There's a sort of continuing theme surrounding Sasha's long-distance boyfriend, but it isn't very interesting. I can't figure out who the audience for this book is supposed to be. Anyone who's at all critical of reality show culture probably suspected most of this, and die-hard super fans are probably not going to believe it. The shock and awe could have been accomplished by an essay- a novel is simply too extended a format for the material available.
