Angel Victoria is on a mission from God: Save the illegitimate royal Catherine Carey from the dark ones.
Vampire Vance is on a mission from the head vampress, Cleopatra: Bring Catherine Carey into the coven so she can lead them to victory over the humans.
When the angel and the vampire meet, sparks fly. A bird may love a fish, too, but where do they reside?
