Secret Rituals - Morgan Knight Mysteries, #1

Morgan Knight is many things: security company owner, a sheriff deputy's widow, and an expert in alternative religions and occult practices. After local law enforcement finds human remains and evidence of unusual ceremonies, it all points to some sort of occult ritual, and Morgan's late husband's captain taps her to help him solve the case. Her expertise will also prove useful in helping a grieving grandmother make sense of her late grandson's descent into the darkest of occult practices.
Mysterious writings and grimoires seem a strange and curious bend for the young man. Her expertise and wit will be soon pushed to the limit, when dark forces pick her as their next target. A descent into the dark beliefs that surround us, 'Secret Rituals' is the first book in Jo Beekman's series of occult mystery novels.
