Killer of the Night

Gale is a regular sixteen year old teen who has never gotten into trouble. Her rich, partying parents could care less about what she does in life, so she's free to come and go.
Then, one night she disappears and doesn't come back for almost a week- and when she comes back, she's nothing like she was before.
Her parents don't know it, but now she's a "creature of the night"- or vampire, as people now a days call it. She wants to be normal again, a human who can escape everyday pains, who doesn't have to worry about killing their best friend.
Then, her killer comes back- and he wants her to go with him.
