This book was incredibly dull and poorly written.
The majority of it is about wanna-be models who, while hoping for their big break, partied too hard and were "sexually abused" (as the author phrases it repeatedly) by men that like to hang around the fashion scene looking for naive girls. A typical passage: "Rio spent the next four hours convincing me how dangerous modeling has become. She admitted she had been beaten, held at gunpoint by a jealous boyfriend, and raped at least six times." Details about her harrowing ordeals follow ("Get out, get your hands off me", Rio yelled).If you find that interesting then this book is for you because much of it is just like that.
There are some pages about models that I have actually heard of (Halperin on model Kate Moss,"[She] appeared to be a beautiful, intelligent, and complex woman possessed of a smoldering sensuality.") But it's all recycled gossip told in a National Enquirer style but with a more pro-model spin. Naomi behaves badly because she has been "victimized by people who are trying to take advantage of her wealth and fame", Gisele Bundchen has become more famous because she dated Leonardo Dicaprio..and so on.
The insider slant, the author was a "model undercover" in L.A. not exactly a modeling mecca like New York, is rendered ridiculous as soon as you see Ian Halperin's picture. Not exactly model material.
I recommend instead Michael Gross' "Model: The Ugly Business of Beautiful Women". It's money much better spent!
