The Da Vinci Code
by Dan Brown

The stakes are raised when Langdon uncovers a startling link: 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. Langdon suspects they are on the hunt for a breathtaking historical secret, one that has proven through the centuries to be as enlightening as it is dangerous. In a frantic race through Paris, London, and beyond, Langdon and Neveu match wits with a faceless powerbroker who appears to anticipate their every move. Unless they can decipher the labyrinthine puzzle in time, the Priory's secret -- and an explosive ancient truth -- will be lost forever.
