Skerryvore tells the story of teenage twins, Rose and Daniel, whose father is abducted by the shadowy organization he used to work for. Rose and Daniel are whisked off to an old house called Skerryvore on a remote Scottish island where they begin to learn the secrets of a world-wide conspiracy that their father was involved in.
Under the guidance of the house's strange owner, Mr Humblestone, the twins begin to learn the secrets of Skerryvore - secrets that link them to a Dark Age king and queen, to a secret society seeking world domination through some of the world's biggest corporations, and to a centuries-old plot to tap into a latent energy source that links some of the world's most ancient and mysterious sites.
