Eva has spent her entire life being treated like a servant in her own home. While her stepsisters live in comfort, Eva works from sunrise to sunset, enduring every insult and punishment in silence. But one cruel night, when she is forced to sleep outside, fate brings a wounded stranger into her path. He is no ordinary man. He is Adrian—the powerful Alpha of the largest werewolf kingdom—and he is dying. Desperate to survive, Adrian marks Eva before disappearing into the darkness, never expecting to see the helpless girl again. But fate has other plans. When Adrian returns to his palace, he is pressured to choose a mate. Every eligible woman is presented to him, including Eva's beautiful stepsisters, Catherine and Mary. Yet none of them are his true match. Until Eva's stepmother convinces the Alpha that Catherine is his destined mate. Catherine moves into the palace, preparing to become Luna. Meanwhile, Eva discovers a secret that could destroy everything—she is carrying the Alpha's child. Thrown out by the family that never loved her, Eva finds herself alone and abandoned. Until Adrian finds her. He brings her to his palace, determined only to protect her and his unborn heir. But the more time they spend together, the harder it becomes for Adrian to ignore the strange pull he feels toward her. And Catherine notices. Jealous and desperate to keep her place beside the Alpha, Catherine gives Adrian an ultimatum: Choose her—or Eva. But Adrian refuses to choose. Then, on the day of the wedding, the sacred Star of the Moon is supposed to reveal Catherine as the Alpha's true mate. Instead, it remains dark. And when Catherine's rage drives her to attack Eva, Eva falls upon the sacred star. For the first time in centuries, it blazes with light. The kingdom finally discovers the truth. Eva was never the unwanted girl. She was the Alpha's true mate. The woman destined to become Luna. And perhaps the most powerful werewolf the kingdom has ever known.
