To Kill a Kingdom

I have a heart for every year I've been alive. There are seventeen hidden in the sand of my bedroom. Every so often, I claw through the shingle, just to check they're still there. Buried deep and bloody. I count each of them, so I can be sure none were stolen in the night. It's not such an odd fear to have. Hearts are power, and if there's one thing my kind craves more than the ocean, it's power.
