In a lovely cottage, there lives a beautiful woman called Ninian who yearns for a family of her own, but whose magical gifts make her too strange to be loved by any local lad. In a castle tower there lives a dark aristocrat called Drogo who studies the stars, seeking rational explanations for perplexing mysteries, unaware that his life is about to be turned upside down by a bewitching enchantress. From the moment they meet by chance in a moonlit forest, they are drawn inevitably together; compelled to act upon an attraction that defies all explanation and breaks every rule.
