Vampire witch hunters (Hansel and Gretel fanfic)

This story is about two kids who get lost in the woods and find a house where they find lots of sweets and a lady who is asleep on a chair. Little did they know that she was a witch who ate children and she was waiting for them.
What will happen when she wakes up and finds these two children? What will the children do?

I don't own hansel or gretel, just my own characters.
