The Lord of the Rings

The Lord of the Rings is an epic high-fantasy novel by English author and scholar J. R. R. Tolkien. Set in Middle-earth, intended to be Earth at some distant time in the past, the story began as a sequel to Tolkien's 1937 children's book The Hobbit, but eventually developed into a much larger work.
