I've changed my ranking. I'm almost in the middle of Last Sacrifice. I usually don't rank a book until I complete it, but the narrative in LS is getting really interesting. It's like a combination of Shadow Kiss and Blood Promise (mostly SK), and many of it's own ideas. Vampire Academy is a fantastic series, excluding most of the narrative in Spirit Bound.
