When the NSA's most classified technological wonder--an invincible code-breaking machine--encounters a mysterious code it cannot break, the agency calls in 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 will 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.

      When world-renowned Harvard symbologist Robert Langdon is summoned to a Swiss research facility to analyze a mysterious symbol -- seared into the chest of a murdered physicist -- he discovers evidence of the unimaginable: the resurgence of an ancient secret brotherhood known as the Illuminati... the most powerful underground organization ever to walk the earth.

      The Illuminati has surfaced from the shadows to carry out the final phase of its legendary vendetta against its most hated enemy... the Catholic Church.

      Langdon's worst fears are confirmed on the eve of the Vatican's holy conclave, when a messenger of the Illuminati announces he has hidden an unstoppable time bomb at the very heart of Vatican City. With the countdown under way, Langdon jets to Rome to join forces with Vittoria Vetra, a beautiful and mysterious Italian scientist, to assist the Vatican in a desperate bid for survival.

      Embarking on a frantic hunt through sealed crypts, dangerous catacombs, deserted cathedrals, and even to the heart of the most secretive vault on earth, Langdon and Vetra follow a 400-year old trail of ancient symbols that snakes across Rome toward the long-forgotten Illuminati lair... a secret location that contains the only hope for Vatican salvation.

      When a new NASA satellite spots evidence of an astonishingly rare object buried deep in the Arctic ice, the floundering space agency proclaims a much-needed victory… a victory that has profound implications for U.S. space policy and the impending presidential election.

      With the Oval Office in the balance, the President dispatches White House Intelligence analyst Rachel Sexton to the Milne Ice Shelf to verify the authenticity of the find. Accompanied by a team of experts, including the charismatic academic Michael Tolland, Rachel uncovers the unthinkable—evidence of scientific trickery—a bold deception that threatens to plunge the world into controversy.

      But before Rachel can contact the President, she and Michael are attacked by a deadly task force…a private team of assassins controlled by a mysterious powerbroker who will stop at nothing to hide the truth. Fleeing for their lives in an environment as desolate as it is lethal, they possess only one hope for survival: to find out who is behind this masterful ploy. The truth, they will learn, is the most shocking deception of all…

      While in Paris on business, Harvard symbologist Robert Langdon receives an urgent late-night phone call: the elderly curator of the Louvre has been murdered inside the museum. Near the body, police have found a baffling cipher. Solving the enigmatic riddle, Langdon is stunned to discover it leads to a trail of clues hidden in the works of Da Vinci…clues visible for all to see…and yet ingeniously disguised by the painter.

      Langdon joins forces with a gifted French cryptologist, Sophie Neveu, and learns the late curator was involved in the Priory of Sion—an actual secret society whose members included Sir Isaac Newton, Botticelli, Victor Hugo, and Da Vinci, among others. The Louvre curator has sacrificed his life to protect the Priory's most sacred trust: the location of a vastly important religious relic, hidden for centuries.

      In a breathless race through Paris, London, and beyond, Langdon and Neveu match wits with a faceless powerbroker who appears to work for Opus Dei—a clandestine, Vatican-sanctioned Catholic sect believed to have long plotted to seize the Priory's secret. Unless Langdon and Neveu can decipher the labyrinthine puzzle in time, the Priory's secret—and a stunning historical truth—will be lost forever.
