Have you read  The Lord of the Rings?
I sure have the Lord of the Rings, is a well heard of novel, by Tolkien!
It is a story about a Hobbit trying to destroy a ring that belongs to an evil being. 
Did do you know that the world they are in is considered the middle-earth which... Is also Nore for human inhabited world?
No, but that is very interesting.  Who are some main characters?
The hobbit, ofcourse!  I was say Frodo out of all  the characters, Sam, Legolas, Aragorn, etc...  Is the best!
