Query: Best Series of books I've read.

This is the best series of books that I have read so far. They are very descriptive and full of vivid detail. The characters are so real. I would recommend these books to anyone who loves to read books. Not only fiction, but romance and historical novels also. They fit so many different categories that you can't really put them in just one
