Inferno

Professor of symbology Robert Langdon wakes up in a hospital in the middle of the night, disoriented and with a head wound. He remembers nothing of the last thirty-six hours. Neither how he got there, nor the origin of the macabre object that the doctors discover among his belongings. Langdon's world soon descends into chaos, and he is forced to flee through the streets of Florence with a clever young woman, Sienna Brooks, whose skillful maneuvers save his life. Langdon quickly realizes that he is in possession of a series of disturbing codes created by a brilliant scientist; a genius whose obsession with the end of the world is matched only by his passion for one of the most influential masterpieces ever written: Inferno, Dante Alighieri's dark epic poem. In their escape through such well-known locations as the Palazzo Vecchio, the Boboli Gardens, and the Duomo, Langdon and Brooks discover a network of hidden passageways and ancient secrets, as well as a terrifying new scientific paradigm that could be used to improve life on Earth... or to destroy it.
