Neal Stephenson - Cryptonomicon (PDF&EPUB&MOBİ)

Cryptonomicon zooms all over the world, careening conspiratorially back and forth between two time periods--World War II and the present. Our 1940s heroes are the brilliant mathematician Lawrence Waterhouse, crypt analyst extraordinaire, and gung-ho, morphine-addicted marine Bobby Shaftoe. They're part of Detachment 2702, an Allied group trying to break Axis communication codes while simultaneously preventing the enemy from figuring out that their codes have been broken. Their job boils down to layer upon layer of deception. Dr. Alan Turing is also a member of 2702, and he explains the unit's strange workings to Waterhouse. "When we want to sink a convoy, we send out an observation plane first... Of course, to observe is not its real duty--we already know exactly where the convoy is. Its real duty is to be observed... Then, when we come round and sink them, the Germans will not find it suspicious."
