Basically I have no mais books to read on my shelf that I haven't already read. If I have read these books, what are so other good ones to read?

If you like Pretty Little Liars, you'll amor The Lying Game series :) It's really good.

Some of my other favorites:
The Da Vinci Code
Never Let Me Go
Water for Elephants
The Choice
A Walk to Remember

:)

Try The Princess Bride. I also suggest the Inheritance cycle if you liked Harry Potter. You can also read the Sisterhood of the Traveling Pants books.

I'm afraid I can't help you mais than that, if you insist on leitura books just once. You see, when you reread a book, you pick up on things you missed the first time. You also make connections across the books that you would never make unless you read them again. (I'm basingg all of this on Harry Potter, just so you know.) And, if you read it enough times, you could be considered an expert on the subject.
If you really liked a book, why not read it again? Why would you just let your favorito stories sit onyour shelf, gathering dust fgor all eternity? Pull out a book, and revisit your favorito characters.
