Inferno by Dante Alighieri

Thirty five years old Dante is lost in a dark wood, assailed by beasts he cannot evade. Dante is rescued by Virgil, and the two of them begin their journey to the underworld where each sin's punishment is a contrapasso, a symbolic instance of poetic justice. Inferno is the first book in the Dante's Divine Comedy trilogy. Dante's Inferno is the original work which inspired Dan Brown's Inferno novel, EA's computer game Dante's Inferno and an animated epic Dante's Inferno.
