— The Hacker Crackdown: Law and Disorder on the Electronic Frontier, by Bruce Sterling.
— The Cuckoo's Egg: Tracking A Spy Through The Maze Of Computer Espionage, by Cliff Stoll.
Both are excellent reads, and if you like old Usenet and BBS stories, you'll be served.
EDIT: By the way, the first one is freely available here: http://www.mit.edu/hacker/hacker.html. I have it in paper myself, but surely it is possible to make a good ePub from these HTML pages.
