What are some really good AP level books to read?

I'm in AP language class right now and I enjoy reading. I would like to read some AP levels books that I would actually enjoy.

Here's a list of books that I have already read and enjoyed;

1984

Animal Farm

The Bean Trees

The Poisonwood Bible

All of Orson Scott Card's books.

All of Dan Brown's books.

The Pillars of the Earth

and many more, but those are the main ones.
