My Guardian Angel

Hannah is 11, autistic, and due to her condition, unable to speak. She had a twin called Angel, but when Angel died, Hannah was forbidden to grieve by her abusive parents and punished when she sought comfort from her sister's things. So now Hannah lives locked inside a silent life of despair, which she fears, will soon end at the hands of her parents. However when a knife keeps appearing under her pillow, and a voice that she thinks is inside her head, won't leave her alone, Hannah begins to realize that just maybe, she may have an ally not of this world, but fear paralyzes.
