The plot is basically this .... Cushla, the fairy princess without a heart (the compassion fairy was late) has come to earth with one mission .... to break up loving relationships. To do this she seduces one of the parties to a relationship and we, the reader, get to watch the demise of that relationship and all the guilt, hatred and desparation that follows. Hillarious, with plenty of perceptive observations as to the nature of relationships today. Read this book, especially if you've just come out of a relationship and are feeling, how shall we say, slightly twisted.
