Sorry if this has already appeared in previous posts, but i found Underground a good read and is available online at http://www.underground-book.org

It basically takes an Oz look at hackers in the late 80's and early 90's and for those old enough to remember, the names Electron, Force, Mendax, Pheonix, Anthrax and Prime Suspect feature prominently. There is also chapters on Parmaster (US) and Gandalf and Pad (UK), all subjects of the hacker takedown of the era.

Is well written and gives a bit of an insight into the minds of these obvioulsy quite talented but misguided individuals - follows their exploits, capture and ultimate punishment. The book also follows up with a sort of "What became of" for these individuals.
