The Two Towers is the second part of J.R.R. Tolkien’s epic adventure The Lord of the Rings. The story continues the quest of Frodo and his Companions of the Ring as they face various dangers in their mission to destroy the Ruling Ring in the Cracks of Doom. They have endured the loss of Gandalf in the Mines of Moria and the betrayal of Boromir, who was corrupted by the Ring's power. As Frodo and Sam journey away separately down the River Anduin, they are not alone, for a mysterious figure shadows their every move. This book marks a continuation of the tale that began in The Fellowship of the Born into a powerful climax in The Return of the King.
