Angels and Demons (2009)

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. When Langdon learns that the clock is ticking on an unstoppable Illuminati time bomb, he jets 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 a 400-year-old trail of ancient symbols that mark the Vatican's only hope for survival.
