Had I not read the first installment of the Twilight saga a couple of years ago, this horror of a novel would probably be the worst book I've ever read.
Looking at the title, at least I cannot say that I wasn't forewarned, so I guess it's my own fault. This book really does come as advertised - it's about sex and violence. In Hollywood. More violence than sex, actually, although neither is lacking, with a pinch of legal drama in the style of the OJ trial thrown in.
A despicable young idiot that has everything in life, because he is a son of a successful, albeit major asshole of a screenwriter, decides to kill his family. Sure, they're assholes and some of them might even be scheming to take their money away and/or possibly kill him and the father, but hey, I guess one day he just wakes up and decides to blow them all away.
Everyone in this book is a depressed, violent, sex-obsessed, gore special effect-making psycho that wants to kill their parents, for mostly non-obvious reasons, like because they're hippies and treat their children nicely. There is not a single likable, non-deranged, normal character in this book.
I don't know what his parents did to Mr. Garton, but if I were them, I'd be in fear of my life. Only recommended if you like gore, violence, violent sex and idiotic, deranged, hateful and unrelatable characters.
