EH-Net

I finally had a chance to dive in to Gray Hat hacking here recently, and it's not quite what I thought it was going to be.  I need something heavily focused on actual net pen testing, and this one falls flat in the middle where it delves off in to programming, reverse engineering, malware analysis, etc.

So, if you had to rescue one net pen book from your burning home, which one would it be?  :)

Thanks!

There is no 1 book that can cover such a vast topic but if you are interested in some good books, here is what I am reading and have read in the past couple of months:

Advanced Penetration Testing for Highly-Secured Environments
BackTrack 4
Hacking The Art of Exploitation, 2nd Edition
Metasploit - The Penetration Testers Guide
Professional Penetration Testing
The Web Application Hacker's Handbook
Counter Hack Reloaded 2nd edition

I am just getting started in pen testing so some of the above might be to basic for you, such as the BackTrack 4 book which basically just gives you an overview of all the tools available in BT.

http://www.amazon.com/Penetration-Testers-Source-Toolkit-Edition/dp/1597496278/ is another decent general tools book.

I'd probably start with Counterhack if I had to pick one though.
