I haven't gotten my hands on a copy yet, but I've seen the table of contents and bits of text here and there. The book covers how cheating in games works with enough details (it appears) to do it yourself, how money is made, legal issues, the problem with bugs, and a bit about how to protect yourself. Most of the book covers cheating and hacking, so if you're interested in hacking around a game, it looks like you'll get a sophisticated how-to lesson. Gary has posted the preface to the book on his on blog, which will give you a better idea of what the book is about. It's supposed to be out today, but Amazon is still saying pre-order, so maybe it goes online at 9 a.m. or something. When I get my copy, I'll post a more thorough review.
