The Alpha's Caged Canary

Nola, an ordinary Omega, is held captive in a castle by Damian, the Alpha of the Howling Moon Pack. Then she finds an old childhood photo in his room and realizes the girl Damian has loved since he was young looks exactly like her. Convinced she's nothing more than a substitute, Nola decides to find his first love for him in exchange for her freedom. But at a banquet, when Vera, the heiress of the Silvermark Pack, openly provokes her, Damian silences everyone by kissing Nola and staking his claim. That night, Nola escapes under the full moon, only to be hunted down by assassins sent by Silvermark and driven to the edge of a cliff. Just as she's about to die, a hidden bloodline awakens within her, revealing white wings and golden eyes. But the awakening is cut short, and she collapses. Damian arrives just in time to save her. And when he interrogates the assassin, he discovers that someone far more powerful has been pulling the strings.
