A vampire lord has fallen for a human girl, and inevitably takes her for his bride. Such a pairing had never occurred before them, thus this caused a lot of controversy among fellow creatures of the night.
Not only must he worry about keeping his love safe from his world before the time comes to turn her, but a strange, yet miraculous thing happens. She becomes pregnant with the first hybrid....
(It doesn't have to be a vampire lord, can be any thing you would like *Not animal, demon is fine though* it was just my original idea)
I'm very open to ideas :)
