This book provides pretty decent accounts and insights into the activities of the people of Anonymous. If you don't have a good idea of what hacking is or the various types of hacking, then Parmy Olson does a good job explaining those to you. It can get a little over the top at some points, but it's probably needed for the average reader. Overall, this book was good, but at times was just a copy and paste of text from a chat rather than real in depth opinion.
