Holly has been mortal all her life. Now at thirty-eight, her fairy godfather arrives to tell her she's a witch, and suddenly she's having to come to terms with the uncertainties of an alarmingly magic-fuelled world. Magic is not like it is in the books and films, and Holly starts to doubt whether her fairy godfather, Partridge Mayflower, is the fey, avuncular charmer he appears. When appearances are magically deceptive, Holly cannot afford to trust those closest to her, including herself. Accidents start to happen, people die, Old Magic is on the hunt, but in the age-old game of cat and mouse, just who is the feline and who is the rodent?
