The Ice Twins is about a young couple Angus and Sarah Moorcraft with their two young identical twin daughters, Kirstie and Lydia.  A year after the loss of one of the couples’ daughters in an accident, the family decide to move to the tiny Scottish island of Torran near Skye which Angus inherited from his grandmother.  As the Moorcraft family try to adjust to their new home, the surviving twin daughter Kirstie starts displaying unusual behaviour, insisting that she is actually Lydia and that it was Kirstie that had died in the accident.  What really happened to to the Moorcraft twin daughter, this is a page turning thriller into the secret world that twins share.
