Dont know if you've seen this, its not really book category, I found an MMORPG called Cyber War..
www.cyberwars.comThe year is 2020. All civilization has gone under. There is now a raging war between the Net Guards and Hackers, good and evil. It's up to you to take a side, and fight for what you think is right. Riches, fame, and power await you... Can you handle it?
Looks kind interesting, I think I'll take a closer look, it says on there forum page under hacking, Discussion of DDOS attacks, SQL injection, XSS, and other site vulnerabilities. NOT an open discussion for "how to's" on attacking websites. and straight away someone has posted need wireshark assistance!?! Rofl.
This looks like a pretty long list of literary works worth a glance.. Love the site there advertised on..
