What this book is about

Interweaving two storylines sixty years apart, Cryptonomicon follows mathematician Lawrence Waterhouse helping crack Axis codes in WWII alongside marine Bobby Shaftoe, while in the present, Lawrence's grandson Randy Waterhouse and his business partners try to establish a data haven in Southeast Asia. Stephenson's enormous, technically demanding novel is a love letter to cryptography, information theory, and the question of who should control the world's secrets. Deeply researched, wildly inventive, and occasionally demanding of the reader's patience.
