Master Me — Meagan Hill

Five years after being kidnapped, Miranda faces an impossible decision: become evil by kidnapping an innocent girl for a sacrificial rite, or allow her captors to murder her. Then she meets Mitch who offers her a way out. Miranda and Mitch must work together to release Miranda from evil's clutches while testing the Fates to discover if they are mated for life or if Mitch must choose between loving Miranda and becoming head of his coven. Becoming as intimate as two people can, both mentally and physically, they must learn to trust each other and those around them as they face death while attempting to rescue the young girls Miranda left behind.
