Cliffs of the Severn is a peaceful haven of narrow streets, tall trees, and water views, a perfect setting for a writer like Alice. Then, one of her friends decides to call up an incubus, a male sexual demon. Alice arrives too late to stop the ritual, but just in time to be affected by the infernal forces that have been summoned. Homicide Detective, Nick Shea, also considers the Cliffs a quiet neighborhood, until two dead eagles and a human heart in a take-out carton are found in an unfinished septic tank pit.
