Query: A Fantastic Book

Not your typical 'tell all' Hollywood book. Prisoner of X is an extremely well written and compelling book. Allan MacDonell balances his scathing view of Hustler and Larry Flint with a self effacing look at his role in the last 20 years of Hustler Magazine. Some really great 'behind the scenes' stuff, some of which is completely unforgettable. This is the kind of book you buy and can't put down!
