Inferno : a novel
(Book)

Harvard professor of symbology Robert Langdon awakens in a hospital in the middle of the night. Disoriented and suffering from a head wound, he recalls nothing of the last thirty-six hours, including how he got there ... or the origin of the macabre object that his doctors discover hidden in his belongings. Langdon's world soon erupts into chaos, and he finds himself on the run in Florence with a stoic young woman, Sienna Brooks, whose clever manuevering saves his life.
