So, I would have liked to start this on day one, but I guess late is better than never.

I started writing a story about a girl who owns a demonic/magical (I haven't decided yet) locket that turns her into animals/demons (I haven't decided yet) when she makes a sacrifice of her own blood to it. She gets out of several problems using this trick, but I'm thinking she'll realize that every time she does it, a piece of her soul dies. Or something. I literally just thought of this now. It's not very well developed yet!
