Secret of Black Rock Mountain by Robin Murphy

Marie and the SIPS team receive a frantic call from a young psychic they met on their psychic kids' retreat. She is experiencing terrifying visions of a group of burnt bodies with their throats cut tied to a Witness Tree, with cryptic symbols carved into their bones.

Marie and the team delve deep into the mystery surrounding witches and wizards. With the help of a witch hunter and a priest, they need to piece together the clues before the blood moon rises.

In the sixth book of Marie Bartek & The SIPS Team, the ghost investigators are once again pitted against evil. But can they bring order back from chaos?
