Vampire and Slayer

Aerie Millon was but one of a million slayers in the world, but 3 things set her apart.
First, she was the best slayer known to all of creature kind in over a hundred years.
Second, she was in love with vampire.
And third, he wasn't entirely dead.

Sixteen year old Aerie Millon was the best vampire slayer in the world in over a hundred years. She'd killed more vampires than any other living slayer and very sternly believed every vampire should die. What happens when sexy seventeen year old Ben comes to her town? He looks human, feels human, eats like a human, but she can tell he isn't. What does that make him though? And does it go against her morals to let him live?
Is there a possibility that he could be a vampire? And will she be forced to kill him? Can she as she swiftly falls in love with him?
