Wolf of Her Own by N.J. Walters

Mikhail Matheson came to Salvation for his sister, but he stayed for Elise LaForge. She’s the alpha’s mother and the most fascinating woman he’s ever laid his eyes on. He’s wanted her from the first moment he saw her. He may feel like an outsider in the pack, but there’s no way he can leave when he’s sure Elise is his mate.
Elise’s made a home in North Carolina with her adult sons and their pack. It’s taken her a long time to get over the years she spent with her abusive mate, and while she’s content now, she can’t help but feel there’s something missing in her life. Mikhail stirs emotions in her she never expected to feel, and the attraction between them is off the charts. But Elise’s not sure how her sons and the pack will react, not to mention the danger the pack is facing.
