Is Kim Harrison making any more books 4 the Rachael M Dead Witch Walkin series after White Witch Black Curse?

I know she made other books with rachael in them that were like added on the side with other authors but i was wondering if there's going to be an 8th book after White Witch Black Curse for the main series? Any info-thanks. I love her stuff, it's the only series I will read more than once. I've read her books numerous times, actually. XD
