For thousands of years, the Pantera and Lupina clans have been mortal enemies, always on the brink of a war that could shatter the world. For Kadence Riley, daughter of the Clan Leader, there has only been one goal: to become like the rest of her family-strong, fast and lethal. When the moon rises on her eighteenth birthday, she'll learn whether or not she carries the Skin-walker gene... and whether or not she'll be cast out to live in the human world, never to see her family again. But when the moon finally rises and the cracking of bones follows, the white fur of her family does not grow on her skin. The howl of a wolf does not escape her lips, and a warm-welcome is the last thing on her clan's minds. Instead Kadence has become something else: one of her clan's greatest enemies. Hunted, heart-broken and lost, Kadence is forced to run from the world she grew up in and learn how to fight for a place in the midst of creatures she has been taught to hate, and when the inevitable war begins to unfold, Kadence will be forced to choose, once and for all, which side her loyalties lie.
