"The darkest places of hell are reserved for those who maintain their neutrality in times of moral crisis."
Symbology professor Robert Langdon wakes up in a hospital in the middle of the night, disoriented and with a head injury. He doesn't remember anything from 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 is soon thrown into chaos and he is forced to flee through the streets of Florence alongside a clever young woman, Sienna Brooks, whose clever maneuvers save his life. Langdon soon 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 greatest masterpieces ever written: Dante Alighieri's dark epic poem Inferno.
On their escape through such familiar settings as the Palazzo Vecchio, Boboli Gardens, and the Duomo, Langdon and Brooks uncover 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.
