"On Midsummer night on the Glastonbury Tor, Alys Hollingberry suddenly dies. Sabbie Dare is in shock over the news, and when Alys's shamanic guru confesses that she may have unwittingly taken drugs during his ritual, Sabbie's shock turns into horror.

After receiving sinister, anonymous emails about Alys, her grieving husband Brice approaches Sabbie for help. She turns to the spirit world for guidance but receives only conflicting and enigmatic answers. She tries seeking help from her boyfriend, Detective Inspector Rey Buckley, but he is embroiled in problems of his own. As she heads closer to the truth about Alys's death, a deranged killer is also heading towards a final victim, and both are closer to Sabbie than she knows."

Between Daphne Du Maurier and Poldark, I'm a little obsessed with tors... just saying.
