Oh I have!
They are pretty good, at first i didn't think they were, but that was just because I had just read Twilight and I was totally caught up on it but after reading it a second time i loved them, but that is just me.
You really should read them but you MUST read them in order, I know that sounds stupid but Twilight wasn't in our library but New Moon was n i was desperate to read the serie so I read New Moon and I was really confused.
so, you really should read them!!!
