The ice twins (engelsk)

A year after one of their identical twin daughters, Lydia, dies in an accident, Angus and Sarah Moorcraft move to the tiny Scottish island Angus inherited from his grandmother, hoping to put together the pieces of their shattered lives. But when their surviving daughter, Kirstie, claims they have mistaken her identity - that she, in fact, is Lydia - their world comes crashing down once again.
