The Return of the King

 The Return of the King by J.R.R. Tolkien (1955) 595 Pages

The quest continues. Frodo and Sam struggle deep within Mordor. Gollum has led them through the most challenging parts, but eventually attempts to betray them with Shelob, the giant spider like creature who kills orcs and whatever else she can find within her cave. Sam and Frodo eventually do make it to Mount Doom. Aragorn elsewhere leads the battle against Sauron's evil forces in the city of Minas Tirith. 

In the end, the one ring is destroyed when Gollum bites the ring off Frodo's finger, and falls into the Cracks of Doom. Sam and Frodo are saved by the great eagles. In that instant, Sauron's power fails and Aragorn is able to crush the remaining evil at the Black Gates. Later, he is crowned King of Gondor, his rightful title and marries Arwen, daughter or Elrond. 

The hobbits return to the Shire, which has been overrun with men who set up an oppressive police state. They overthrow this institution and find out Saruman is behind it. Frodo spares him, but dies anyways due to betrayal by Wormtongue. The Shire is rebuilt, Frodo decides to leave and sails away to the peaceful paradise in the West with Bilbo, Gandalf, and the other ring bearers. 

10/10 this is my favorite ending to a fantasy series. I love re-reading, it never gets old!
