What terrifying discovery would make the Vatican turn to Robert Langdon, the man who cracked history's most controversial code? When Langdon discovers evidence of the resurgence of an ancient secret brotherhood known as the Illuminati - the most powerful underground organization in history - he also faces a deadly threat to the existence of the secret organization's most despised enemy: the Catholic Church. Upon learning that the clock is ticking on an unstoppable Illuminati time bomb, Langdon travels to Rome, where he joins forces with Vittoria Vetra, a beautiful and enigmatic Italian scientist. Embarking on a nonstop, action-packed hunt through sealed crypts, dangerous catacombs, deserted cathedrals, and even to the heart of the most secretive vault on earth, Langdon and Vetra will follow the 400-year-old Path of Illumination that marks the Vatican's only hope for survival.
