Plot summary.
Nikki Black, a disturbed and hate-filled young woman intent on punishing the mother who abandoned her at birth goes to the island with only one aim in mind: revenge. Her plans are confounded by the discovery that she has a brother, Calum: a brother strangely possessed by their mother; a brother with a terrifyingly violent streak; a brother whose dangerous love and strange way of seeing the world transform Nikki's life. The characters Calum and Phyllis are loosely based upon Caliban and Prospero.
