The hobbit, or, There and back again
Bilbo Baggins enjoys a quiet and contented life, with no desire to travel far from the comforts of home; then one day the wizard Gandalf and a band of dwarves arrive unexpectedly and enlist his services - as a burglar - on a dangerous expedition to raid the treasure-hoard of Smaug the dragon. Bilbo's life is never to be the same again.
