No, none of the books so far have anything on turning a witch into a were or vampire. I asked the vampire question in another thread (I think Thoughts & Questions).
My question dealt with turning a witch into a vampire. Would they keep their powers? If they did would those powers grow as they aged, like other vampire powers?
I’m actually a bit surprised Stacia hasn’t bitten or nipped him in the heat of the moment, either in training or in bed. Her LV is apparently a good strain, having been modified by Chris’ blood & aura.
