Insanity

This is about a girl who's dad is, what you would call, an evil scientist and he tends to experiment on people. He had experimented on the girls mother till she died so he started to experiment on the girl shortly after. She has lived in her dads lab for years and knows nothing of the outside world. Until one day three teens find the house that the lab is in, abandon, and they explore it until they run across the girl. They figure out that she is alone and was abandoned so they take her with them, but they have to keep her hidden from their parents so they hide her in their club house in the woods. But what they don't know about her could possibly get them killed along with everyone around them. Because she doesn't want to lose the only good thing she has to other people. She wants them all to herself.
