On the morning of her mating ceremony, Lydia Vance is abandoned by her fiancé, Ethan Ashford, who runs off to care for his childhood sweetheart. Humiliated in front of both families, Lydia refuses to let the wedding collapse. In desperation, she calls Orion Silvermoon—her powerful seven-year rival—and asks him to become her groom. What begins as a fake marriage quickly turns into something far more dangerous. Orion protects her, challenges her, and reveals a secret he has hidden for years: Lydia was never his enemy. She was the woman he had loved all along.
