A horrific tale of ancient clans and legends from the very beginning of time... The Unknown One strikes at will, always in darkness, leaving behind wolf-like tracks five times larger than any wolf. Its bite causes a disease which takes over the body and controls the mind, if the life is spared at all. Snapping a hurried glance around the campsite, Bella – or the creature Bella was now becoming – stretched backward, arching her spine, feeling the painful shoving and tugging in each joint of her body as the muscles and sinews stretched and became the more powerful, much more heavily-built shape of the beast... Then the clan discovers they are being stalked – not only by a clan of flesh-eaters, but also by a Sabre-Tooth Tiger. How can they survive such onslaughts?
