The Insane Go Here: Kill the Willow

Willow, the main protagonist, is a girl who gets bullied severely. Her mother has recently passed, leaving her hopeless about good in the world. However despite her thoughts on the world, she gets invited to a party. She goes to it and things take a turn for the worse. She ends up in the woods where she meets an interesting character.
This is all about the extreme side of bad in the world and the side of the world that is usually what people refer to as 'things that go bump in the night'.
