Seraphina’s wedding is shattered in an instant. Her fiancé Damon shows up with his pregnant mistress Layla, calls off the marriage in front of everyone, and tells Seraphina to raise their child. Refusing to be broken, she offers herself to any wolf in the clan who will claim her—but Damon’s influence keeps every man silent.
Then her cursed half-brother Kyle, unable to transform, steps forward and claims her. The bond awakens a buried curse, and Seraphina counters it with her silver blood, sealing a shared mark between them.
As she continues easing Kyle’s curse each day, his strength returns and his gift for leadership begins to show. He slowly wins over the clan, while Damon, stripped of his right to inherit, grows consumed by jealousy. He teams up with his supporters to frame Kyle, and when the lie falls apart, he pushes for a full-moon duel to take back Seraphina and the throne.
Under the full moon, Seraphina finally breaks the curse completely. Kyle transforms into a silver wolf unseen for a thousand years and overwhelms the clan with his power. Damon, Layla, and Damon’s mother Moira all face their downfall and punishment. In the end, Kyle is crowned king, Seraphina becomes the Moon Queen, and their destined love stands unshaken.
