What are good books to read?

I am thirteen right now and I like fantasy stuff. I have already read Harry Potter ( my favorite series ever), Twilight, The clique, Narnia, the Hobbit, Nancy Drew, etc. What are good books like that to read? I was also wondering, is the Lord of the RIngs a good series? What about the Ugglies series (I have only read the first one. My friends say the rest wre good. what do you think?). Thanks
