Strange & Deadly

Penelope is strange. She dislikes normal, likes to dress as a Victorian lady, and is haunted by lost souls like a magnet. She lives in a cottage with her cool, older, hip sister just outside of their town, Grey Waters. They're normal girls at day, but at night, they become the strange.
Xander is deadly. He hates weak people, likes to wear all black, has some anger problems, and feasts upon the lost souls, sending them to the unknown.
When Xander feels a strong pull of lost souls coming from Grey Waters, he immediately goes to investigate, taking his ego-filled brother with him. But with each lost soul he sends, the dark part of the soul stays attached. To him.
Except, when Xander sets his eyes on Penelope, it's like a flicker of light. There's something strange about her. She is a flame in the dark. But it won't be long before Xander becomes consumed in the souls darkness and Penelope is hoarded by them.
