Murder at the Mill — Lynn Marron

When police Sgt. Paul Travinski is accused of murdering his ex-best friend. Holly Corey suspects he may have been a victim of malicious witchcraft. Trying to aid the man she loves, Holly stumbles on yet another coven of witches near the New England harbor town of Mystic Connecticut. This coven is mastered by the very handsome young Warlock, Colin Fitzgerald. Trying to learn more about what happened to Paul and how her mother really died, Holly gets a job at Colin's successful farm-stand, now a huge barn selling plants, tourist items, and occult paraphernalia. With the spring fertility rites of Beltane coming up, Colin is courting Holly against his reclusive mother's wishes. And for those rites, the malicious Lillith Hoyt wants Holly up on the outdoor altar recreating the sexual union of the Lady and Lord. Just before Paul goes into custody, he tries to prevent this. Holly certainly doesn't want to have sex at midnight before an entire covenant gathering from around the world, but will she do it to save Paul? Even if by bedding Colin she ends her chances with her stubborn sergeant?
