Used book – Inferno, Dan Brown

Robert Langdon, a Harvard professor of symbology, wakes up in the middle of the night in a hospital. Disoriented, with a head injury, he has no recollection of the last thirty-six hours. Why is he in Florence? Where did this macabre object that doctors found in his belongings come from? When his world abruptly turns into a nightmare, Langdon decides to flee with a young woman, Sienna Brooks. Langdon quickly realizes that he is in possession of a coded message, created by an eminent scientist who dedicated his life to preventing the end of the world, an obsession matched only by his passion for "Inferno," Dante's great epic poem. Caught in a race against time, Langdon and Sienna do everything to find the scientist's ultimate creation, a ticking time bomb, of which no one knows whether it will improve life on Earth or destroy it.
