The Hobbit: Or There and Back Again (Lord of the Rings)

Version illustrated by the author here

The adventures of the well-to-do hobbit, Bilbo Baggins, who lived happily in his comfortable home until a wandering wizard granted his wish.

Bilbo Baggins is a hobbit who enjoys a comfortable, unambitious life, rarely traveling any farther than his pantry or cellar. But his contentment is disturbed when the wizard Gandalf and a company of dwarves arrive on his doorstep one day to whisk him away on an adventure. They have launched a plot to raid the treasure hoard guarded by Smaug the Magnificent, a large and very dangerous dragon.

Bilbo reluctantly joins their quest, unaware that on his journey to the Lonely Mountain he will encounter both a magic ring and a frightening creature known as Gollum.
