The Hobbit by J.R.R Tolkien

Bilbo Baggins was a hobbit who wanted to be left alone in quiet comfort.  But the wizard Gandalf came along with a band of homeless dwarves.  Soon Bilbo was drawn into their quest, facing evil orcs, savage wolves, giant spiders, and worse unknown dangers.  Finally, it was Bilbo-alone and unaided-who had to confront the great dragon Smaug, the terror of an entire countryside!
