Well, that's what I did in @War, so I'll recommend you check it out. http://www.amazon.com/War-The-Rise-Military-Internet-Complex/dp/0544251792
@War: Rise of the Military-Internet Complex or Countdown to Zeroday: Stuxnet and the Launch of the World's First Digital Weapon
I've finished @War its a chronicle of the rise of the NSA and cyber-warfare. Half way through Countdown to Zeroday, so far it is really good. Some of the information overlaps with @War but it is more of overall meta information about cyberwar.
You can get both on Audible.
Also if you're not adverse to pod-casts you can easily spend 12 hours listening to Defensive Security Podcast
