In another life, he drove a sword through her heart. In this one… he might do it again. Celeste has spent her life hidden behind castle walls, feared for a prophecy she refuses to believe. Marked as the Shadow Princess, she is destined to either save the world… or destroy it. But when she finally escapes into the outside world disguised as a soldier, everything changes. Because the moment she meets him— her wolf awakens. Darien, the ruthless Alpha King of the Specter Kingdom, is known for his cruelty and power. He doesn’t trust easily. He doesn’t hesitate. And he definitely doesn’t tolerate weakness. So why can’t he ignore the strange pull toward a quiet, sharp-tongued soldier named Wren? As war brews and enemies close in, Celeste’s power begins to awaken—dark, dangerous, and impossible to control. And the more Darien uncovers, the closer he gets to the truth. She is not just a girl in hiding. She is the Shadow Princess. And she may be the very thing he was destined to destroy. But when fate binds them together in a way neither can escape… Darien must make an impossible choice: Fulfill his destiny… or protect the woman he was meant to kill.
