Wicked Devotion by Lila Fox

Faith and her sisters lost the only home and family they had. Their father did the best he could to protect them, but their stepmother made it nearly impossible until her father brought in some trusted friends to help.
Rafael dreaded following through with his promise to his friend, but there was no way he’d ever let the man down. When he met his future wife, he didn’t expect the emotions and possessiveness he felt. Instead of scaring him, he found it a blessing and was glad he had agreed to helping his friend.

The danger he was protecting his wife from was slowly getting closer, and he would do everything he could to keep her with him.
