The narrative is divided into two main storylines. One focuses on Frodo and Sam as they encounter the creature Gollum, while the other follows Aragorn, Legolas, and Gimli as they aid the people of Rohan against the forces of Saruman. The book explores themes of friendship, loyalty, and the struggle between good and evil.
