The book was originally designed to help those looking at doing time in the Federal Prison system, but the author feels it may be read by anyone interested in how life goes on "behind the razor wire." It deals with using your brain and not your muscle to make ones life easier while doing time. It starts from being arrested to the day of release. The legal ways to survive and the not so legal ways are all talked about in this book. The author writes about who really "runs the zoo," and how one can fly under the radar so as to not be targeted by those looking to take advantage of the weak.
