Fragile Bloodlust

Could you kill something that's apart of you? Even if you knew that that something was evil, and needed to be exterminated, could you do it? Zayn can, because shes a vampire hunter. She grew up learning that vampires were evil creatures that needed to be killed, and she truly believed that, until she found out that she was part vampire herself. Living among humans is a challenging enough when you have advanced senses, super strength and agility, and a strange gold rim around your right eye. It's even harder when you start thirsting for your best friends blood. Will Zayn be able to control her blood lust and fulfill her duty as a vampire hunter? Or will she cross over to the dark side, and live among the beasts she's been ordered to kill?
