Tolkien did not design this book as a trilogy, it was suppose to be one book.
Therefore this book has no true beginning and not really a satisfying ending.
But besides that I really loved it.
What I love about these books is the friendships you read about; Merry and Pippin, Frodo and Sam, and even Legolas and Gimli! It's so heartwarming how they look after each other and how their bond grows. The worldbuilding is so amazing and well developed.
These books are full of action scenes, it's so exciting to read!
