Digital Fortress

Before the multi-million, runaway bestseller The Da Vinci Code, Dan Brown set his razor-sharp research and storytelling skills on the most powerful intelligence organization on earth--the National Security Agency (NSA)--in this thrilling novel, Digital Fortress. When the NSA's invincible code-breaking machine encounters a mysterious code it cannot break, the agency calls 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 it would cripple U.S. intelligence. Caught in an accelerating tempest of secrecy and lies, Susan 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. From the underground hallways of power to the skyscrapers of Tokyo to the towering cathedrals of Spain, a desperate race unfolds. It is a battle for survival--a crucial bid to destroy a creation of inconceivable genius...an impregnable code-writing formula that threatens to obliterate the post-cold war balance of power. Forever.

Marshall McLuhan was the greatest prophet of the digital age. In the 1960s, McLuhan, a Canadian literary theorist reared on Elizabethan satire and the labyrinthine novels of James Joyce, turned his attention toward the budding and befuddling electronic age. Like most prophets, McLuhan became one through a fascination with God. Prophets divine their wisdom from a source, and Digital Communion shows that McLuhan's was his own Catholic faith. In other words, the greatest prophet of the digital age was an ardent Christian. A reconsideration of his vision can change the way we view the online world. A Catholic convert, McLuhan foretold a digital age full of blessings and sins: a world where information was a phone call or keystroke away, but where our new global village could also bring out the worst in us. For him, mass media was a form of Mass. McLuhan thought that while the print world was visual, the electric world--especially television--was a medium of touch. It enveloped us. For McLuhan, God was everywhere, including in the electric light. Digital Communion considers the religious history of mass communication, from the Gutenberg Bible to James Joyce's literary forerunners of hypertextual language to McLuhan's vision of the electronic world as a place of potential spiritual exchange, in order to reveal how we can cultivate a more spiritual vision of the internet--a vision we need now more than ever.
