Most places would shelve Cryptonomicon in the Science Fiction section and they wouldn't be wrong. But a more accurate category would be Mystery. Neal Stephenson's sprawling novel takes us from the code crackers of WWII's Bletchley Park to the dawn of the modern internet era. The power of this novel is in its ability to illustrate the interconnectedness of technologies in the 20th century. A church organ, for example, operates similarly to a computer program; or a young Alan Turing, akin to a modern-day hacker. And the battles of WWII move from the battlefield to the boardroom as companies vie for valuable real estate to lay fiber optic wire. But this wouldn't be an international and multi-generational mystery if it didn't have a buried treasure as well. For its length, Cryptonomicon is still a page turner. It's quite the clever read and is recommended for readers of Pynchon and Cussler alike.
More than fifty years after Lawrence Pritchard Waterhouse and Sergeant Bobby Shaftoe are assigned to Detachment 2702, a secret cryptographic mission, their grandchildren--Randy and Amy--join forces to create a "data haven" in the South Pacific, only to uncover a massive conspiracy with roots in Detachment 2702.
