"The reluctant Hobbit hero Bilbo Baggins is asked to join the band, for they can hardly hope to succeed as an unlucky thirteen. Bilbo finally agrees to the adventure! They encounter the dangerous trolls, then escape into Goblin country where Bilbo finds a gold ring with magical power. It's a ring of invisibility. Bilbo is cautious and thoughtful but saves them in every crisis, even in the climactic scene with the dragon Smaug."--Publisher website.
