We couldn’t omit a classic book like The Hobbit not only because is the prequel of one of the best Fantasy Trilogy like the Lord of the Rings but also because it has one of the most famous Dragons in literature, Smaug.
If you just saw the movie please grab the book and enjoy Tolkien’s writing and that goes specially for the ones that didn’t read The Lord of the Rings. You don’t need a Dragon for that. LOTR Is one of the best books in history, period.
