The Babylon series of books is written by Imogen Edwards-Jones with the help of an anonymous source inside the industry she is profiling. Factual information and anecdotes that actually took place are compressed into the space of a week. Perhaps the best known of the series is Hotel Babylon which subsequently sparked a TV program, but other in the series include Air Babylon, Fashion Babylon, Pop Babylon and the two I've just read, Beach Babylon and Wedding Babylon. Believe me - you will learn more about the inner workings of these industries than you ever wanted to know, all told with the best of British humor. Hotel, Air and Wedding are my favorite of the series so far, but rumor has it that another expose is on its way. Can't wait. Recommended.
