J.R.R. Tolkien's The Hobbit

Bilbo Baggins, along with the wizard Gandalf and 13 dwarves led by Thorin Oakenshield, is swept into an epic quest to reclaim the lost dwarf kingdom of Erebor from the fearsome dragon Smaug. Their journey will take them into the wild, trough treacherous lands inhabited by goblins, spiders, trolls and other dangerous creatures! Along the path, the unassuming Bilbo Baggins not only discovers depths of the ingenuity and courage that surprise even himself, he also gains possession of a magic ring tied to the fate of all Middle-Earth in ways he cannot begin to imagine.
