I'm up to book 6, book 7 is on the way. I'm already fretting about when I'm done! I'm waiting for book 8 to be released in MM paperback, so they're all the same. Ack, the hardcover doesn't even release till the end of the month.
Le sigh, Wrath is still my favorite, but I love reading them all. These are definitely my kind of vampires. MMM!
