Oh, ridiculous vampire stories...

So, I have now finished all of LJ Smith's Night World books AND OMG I LOVE THEM SO MUCH I'M ALL WEAK AND TINGLY AND THEY SEE INTO MY SOUL JUST LIKE WE'RE SOULMATES!!!! Can't wait for the final book which is supposed to be out next year but I am SUSPICIOUS because it's so long since the others. ungratefulwench, my source of knowledge in these things: is this something that's been promised for the last decade or something and never yet materialised because if so I will not get my hopes up.
