Cassie Fortuna flees back to her own pack, broken-hearted, after discovering her intended's interest in another woman. Despite shifters being monogamous, it seems Ben isn't.

As her twenty-fifth birthday approaches, and her heat, she resigns herself to returning—there is no one for her in Mystic River and her only sibling and her family live in Blue Star. Besides, she's over Benjamin Kraft.

Ben hopes Cassie came back for him but is unable to breach her cold façade to finally share his dark secret. Secrets have a habit of coming out, however, and Cassie is stunned by what she learns. Intent on making things up to her, Ben succeeds in winning her back. Having never gotten over him, she embraces their new relationship.

But Cassie and Ben could be in danger, as well as someone else important to him when others learn his secret. Is the risk worth the reward?
