1942: Lawrence Pritchard Waterhouse, mathematical genius and young Captain in the U.S. Navy, is assigned to Detachment 2702, commanded by Marine Rider Bobby Shaftoe. 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. Detachment 2702's mission is to keep the Nazis ignorant of the fact that Allied Intelligence has cracked the enemy's fabled Enigma code.

Fast forward to the present, 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 discovers a massive conspiracy with roots in Detachment 2702 linked to another 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.
