Cryptonomicon
Neal Stephenson
 The action takes place in two periods: the Second World War and the late 1990s, during the Internet boom. In 1942, Lawrence Pritchard Waterhouse, a young U.S. Navy code breaker and mathematical genius, is assigned to the newly formed joint British and American Detachment 2702. This ultra-secret unit's role is to hide the fact that Allied Intelligence has cracked the German Enigma code. The detachment stages events, often behind enemy lines, that provide alternative explanations for the Allied intelligence successes. Marine sergeant Bobby Shaftoe, a veteran of China and Guadalcanal, serves in unit 2702, carrying out Waterhouse's plans. At the same time, Japanese soldiers including mining engineer Goto Dengo, an old friend of Shaftoe's, are assigned to build a mysterious bunker in the mountains in the Philippines as part of what turns out to be a literal suicide mission. Circa 1997, Randy Waterhouse (Lawrence's grandson) joins his old Dungeons and Dragons companion Avi Halaby in a new startup, providing Pinoy-grams to migrant Filipinos via new fiber-optic cables. The aptly named Epiphyte Corporation uses this income stream to fund the creation of a data haven in the nearby fictional Sultanate of Kinakuta. Vietnam veteran Doug Shaftoe and his daughter Amy do the undersea surveying for the cables and engineering work on the haven is overseen by Goto Furudenendu, heir-apparent to Goto Engineering. Complications arise as figures from the past reappear seeking gold or revenge.
