His Broken Vow, My Wolf Crown

Eleanor sacrifices her wolf soul to save her fiancé, Adrian, then uses her pure heart to bear his bloodshed curse. He becomes unbeatable in battle. She turns into a black wolf with every full moon. When he returns victorious, he treasures Cecilia, the woman who stole credit for saving his life. For Cecilia, he takes the moonstone keeping Eleanor alive, stabs her in the chest to draw her blood, and even prepares to cut out her heart. Finally, he severs their mate bond himself and sentences her to death. With nothing left to love, Eleanor gives up the cherished memories of their relationship, returns the curse to him, and reveals her true form as the White Wolf Sovereign on the judgment platform. Without her, Adrian becomes the very black wolf he once ordered hunted down. His power fades as the curse turns on him. Under Prince Regent Rowan’s protection, Eleanor breaks her own chains, unites the clans, and exposes the deception. When Adrian learns the truth, he falls to his knees and begs her to come back. She refuses every time. When Cecilia and her father launch a rebellion and take hostages, Eleanor and Rowan join forces to rescue them and crush the uprising. In the end, Eleanor crowns herself and chooses the man who respects her and will defend the kingdom at her side. Stripped of his throne and command of the army, Adrian bears the curse alone for the rest of his life—and dies consumed by regret.
