Digital Fortress

National Security Agency, Fort Meade, Maryland: when the most powerful intelligence organization on earth's invincible code-breaking machine encounters a mysterious code it cannot break, it calls for its head cryptographer, Susan Fletcher, a brilliant and 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 ingeniously complex that if released would cripple U.S. intelligence.

Seville, Spain: the creator of the code, Ensei Tankado, is found dead. And with him has died the secret to an impregnable code-writing formula that threatens to obliterate the post-cold war balance of power. Forever.

From the underground hallways of power to the skyscrapers of Tokyo to the towering cathedrals of Spain, a desperate race unfolds. Caught in an accelerating tempest of secrecy and lies, betrayed on all sides, Susan Fletcher finds herself fighting not only for her country but for her life, and in the end, for the life of the man she loves...

Dan Brown (Author)

Dan Brown is the author of eight #1 bestselling novels, including The Da Vinci Code, which has become one of the bestselling novels of all time as well as the subject of intellectual debate among readers and scholars. Brown’s novels are published in 56 languages around the world with over 250 million copies in print.

Brown was named one of the 100 Most Influential People in the World by TIME Magazine, whose editors credited him with “keeping the publishing industry afloat; renewed interest in Leonardo da Vinci and early Christian history; spiking tourism to Paris and Rome; a growing membership in secret societies; the ire of Cardinals in Rome; eight books denying the claims of the novel and seven guides to read along with it; a flood of historical thrillers; and a major motion picture franchise.”

The son of a mathematics teacher and a church organist, Brown was raised on a prep school campus where he developed a fascination with the paradoxical interplay between science and religion. These themes eventually formed the backdrop for his books. He is a graduate of Amherst College and Phillips Exeter Academy, where he later returned to teach English before focusing his attention full time to writing. He lives in New England.
