After losing her husband, Serena, the grieving Luna of the Winter Pack, adopts Caleb, a mistreated hybrid orphan who bears a striking resemblance to her late love. While Serena views him as a vulnerable servant, Caleb hides a dangerous secret: he is the awakening Lycan King. Behind his mask of a 'loyal puppy' lies a fierce protector ready to slaughter anyone who threatens his mistress. As internal treachery and divine judgment loom over the North, the forbidden bond between the high-born widow and her lowly servant ignites. Caleb must rise from a lowly substitute to a supreme ruler to shatter the divine order and protect the woman who saved him.
