Throwback

Once in many generations, it reappears. Scientists call it a freak of evolution. The people in the hills have another name for it. Throwback. Something preys on your mind even as it grows under your skin. It will sprout a bone structure. Clawing hands. Killing fangs. It will trap you within your own flesh. And if you lose the final, nightmarish war of wills, it will be your master. Forever.
