Death cocktail is what the vampires call a witch's blood. It's poisonous -- a drop will destroy a vampire within minutes. Nikolaus Drake is the rare vampire who has survived his first taste. Now he's on the hunt for the witch who almost brought him to his demise -- Ravin Crosse. A witch who spends her nights hunting vampire tribes, Ravin has three obligations to fulfill to set her soul free. One of those obligations -- crafting a love spell -- twists her world upside down when Nikolaus draws the spell from her veins. Natural enemies rarely make the best bedfellows -- but is it possible their intentions are really, truly the same? Can Nikolaus's tribal loyalty survive if he surrenders to desires far darker than his own?
