Cryptonomicon

Another Neal Stephenson story following 2 story lines: one following code breakers in World War II, another a group of dot com entrepreneurs. Featuring fictionalized versions of names from the time including Alan Turing made it easier to identify with the characters. The first half of this very long book was tough to get through, with most of the payoff towards the end. The detailed descriptions of cryptography and theories about a digital currency were the most interesting part.
