Posting interest. Would a pious young woman who is constantly haunted be an appropriate entry? She would probably be a witch, but somewhat unwilling and unaware of her role in the workings. She just wants to have peace and feel clean again, but at this point the hauntings are so bad that she is forced to face them head on just in an attempt to get her life back. 

That’s the pitch. I’ll write a full app if you like it. :)
