The wolfkin clans have hidden from humanity for eons, treading the line between legend and reality, guarded against those who hunt their kind. Yet despite their caution, the clans are ambushed at a peaceful gathering of their people and the loss of life is devastating, the cost reverberating through the clans for decades. Lost in the aftermath of the ambush and assumed dead by most, the pup Luca is locked inside his wolf, too young to understand how to change back. Adopted by biologists he's raised as a wild animal. The child Luca was is gone, replaced by a fully-grown dire wolf called Ghost. A violent attack at the sanctuary by those who hunt his kind spurs Ghost into revealing his true nature, and eventually, he finds himself on a path back home. As the alpha heir to his clan, Kane has spent years fighting for revenge and justice. He returns to the mountains where their people died, meeting a hauntingly familiar stranger named Ghost. Chaos ensues after the wolfkin's dormant Goddess unexpectedly decides to mate Kane and Ghost. The shocking existence of their bonding flies in the face of accepted wolfkin law and lore. Ghost and Kane unearth buried truths even as betrayal and enemies close in on them, and without the steadfast loyalty and love of family and friends, they may not be safe from the very people they fight to protect.
