Aishling Morgan returns to the sleepy, mysterious environment of seaside Devon, explored in Deep Blue. Someone has been performing the Black Mass in an old, abandoned chapel at Stanton Rocks. The local priest, Tom Pridough, is convinced it was Nich Mordaunt, local high-profile pagan, and his friend, the stunning brunette Juliana. Tired of the churchman's confusion of diabolism with his own nature-worship. Nich too sets out to find out who is responsible, and all three become embroiled in a weired and perverse world of sex-magic beyond their darkest imagination.
