The Hobbit by J.R.R. Tolkien

Bilbo Baggins is a hobbit who enjoys a comfortable, unambitious life, rarely travelling further than the pantry of his hobbit-hole in Bag End. But his contentment is disturbed when the wizard, Gandalf, and a company of 13 dwarves arrive on his doorstep one day, to whisk him away on a journey "there and back again". They have a plot to raid the treasure hoard of Smaug the Magnificent, a large and very dangerous dragon…

The prelude to The Lord of The Rings, the Hobbit has sold many millions of copies since its publication in 1937, establishing itself as one of the most influential books of the 20th century.
