Red Eagles? I'll second the "fun book" comment. I'd recommend it to anyone who has ever enjoyed a Tom Clancy novel.
Blind Man's Bluff is good, as another poster suggests.
Another fun one is "The theory that would not die," about the history of Bayes rule.
Also, broader away from recent military skunk works is anything by Simon Singh, particularly The Code Book and Fermet's Last Theorum.
