The Lord of the Rings series by J. R. R. Tolkien
Frodo Baggins knew the Ringwraiths were searching for him - and the Ring of Power he bore that would enable Sauron to destroy all that was good in Middle-earth. Now it was up to Frodo and his faithful servant Sam to carry the Ring to where it could be detroyed - in the very center of Sauron's dark kingdom.
