Sophie and Hugh are evacuated to Greystones in Ireland when their house is bombed during the London Blitz. Their mother is seriously injured and their father is away fighting in the war, so the children are sent to their grandfather in Ireland. They know very little about him, except that his letters cause trouble at home and their dad never speaks of him.
How will they live with a gruff old man who probably hates them? How will they manage in a strange country where they know nobody? And, most of all, will the family ever be together again?
