Digital Fortress

Cryptographic thriller exposing government surveillance secrets.

If you're into nail-biting suspense with a tech edge, "Digital Fortress" could be your next favorite read. Dan Brown weaves the complexities of code-breaking and the intense pressure of government spying into a story that's as thought-provoking as it is thrilling. It's the kind of book that will make you second-guess every password you've ever created.

Note: While we do our best to ensure the accuracy of cover images, ISBNs may at times be reused for different editions of the same title which may hence appear as a different cover.

Description

When the National Security Agency's invincible code-breaking machine encounters a mysterious code it cannot break, the agency calls in its head cryptographer, Susan Fletcher, a brilliant, beautiful mathematician. What she uncovers sends shock waves through the corridors of power. The NSA is being held hostage - not by guns or bombs, but by a code so complex that if released would cripple U.S. intelligence. Caught in an accelerating tempest of secrecy and lies, Fletcher battles to save the agency she believes in. Betrayed on all sides, she finds herself fighting not only for her country but for her life, and in the end, for the life of the man she loves...
