Olivia Knight

The moment she starts her doctorate in Oxford, Sarah is beset with mysteries. An old portrait in her rented house bears an uncanny resemblance to her. Her new lover insists he's a ghost. Her attractive, sinister supervisor refuses to let her see manuscripts on witchcraft. An ordinary hill on the meadow fills her with fear - and not just her, but also the man with whom she falls in love. Every time she has sex, she hallucinates strange places and other times.
Through sex, magic and orgasmic visions, she must fight betrayal to learn the truth behind the secrets.
