Black Blood

So you say you know about the vampiric war, but what about the war of the witch's? For centuries the witch's and vampires have been at war and finally they come to an agreement, under one condition. One person from each side must marry other wise the war will continue. And sadly for Eva Stone she was the one they picked to marry a vampire. The day her "Fiance" was suppose to come someone else shows up to live with them, not to mention the century old vampires that are after Eva's head. How will she ever live this down?
