"Engrossing - insightful ... fascinating and often hysterical... Cryptonomicon is really three novels in one, featuring healthy portions of World War II adventure, cryptography, and high-tech finance, with treasure hunting thrown in for good measure... But that's only half of it."

"Hell of a read."

Neal Stephenson (Snow Crash; The Diamond Age) hacks into the secret histories of nations and the private obsessions of men, decrypting with dazzling virtuosity the forces that shaped the twentieth century - and that have led us into the twenty-first.

In 1942, Lawrence Pritchard Waterhouse - mathematical genius and young Captain in the U.S. Navy - is assigned to Detachment 2702. It is an outfit so secret that only a handful of people know it exists, and some of those people have names like Churchill and Roosevelt.

The mission of Waterhouse and Detachment 2702 - commanded by Marine Raider Bobby Shaftoe - is to keep the Nazis ignorant of the fact that Allied Intelligence has cracked the enemy's fabled Enigma code. It is a game, a cryptographic chess match between Waterhouse and his German counterpart, translated into action by gung-ho Shaftoe and his forces.

Fast-forward to the present, where Waterhouse's crypto-hacker grandson, Randy, is attempting to create a "data haven" in Southeast Asia - a place where encrypted data can be stored and exchanged free of repression and scrutiny. As governments and multinationals attack the endeavor, Randy joins forces with Shaftoe's tough-as-nails granddaughter, Amy, to secretly salvage a sunken Nazi submarine that holds the key to keeping the dream of a data haven afloat.

But soon their scheme brings to light a massive conspiracy with its roots in Detachment 2702, linked to an unbreakable Nazi code called Arethusa. And it will represent the path to unimaginable riches and a future of personal and digital liberty - or to universal totalitarianism reborn.

A breathtaking tour de force and Neal Stephenson's most accomplished and affecting work to date, Cryptonomicon is profound and prophetic, hypnotic and hyper-driven, as it leaps forward and back between World War II and the World Wide Web.
