When the soon-to-be alpha heir of the Silvercrest Pack, Alden Vale, begins to feel drawn to a quiet, sarcastic new transfer student, Eli Carter, he rejects the idea that he could be attracted to a human. His hatred of human fragility and his obsession with perfection make him cruel and dismissive. But when Alden turns 18, his wolf awakens fully-and he scents the truth. Eli is his fated mate. The mark of the Moon Goddess begins to stir inside both of them, rewriting their fates and unlocking dormant power within Eli-a strange hybrid strength that could change the balance of all packs. However, Eli isn't forgiving. He's furious. Betrayed. And his presence begins to awaken ancient forces tied to the Moon Goddess herself-forces that other packs will soon notice.
