Spring 1935. On London's Hampstead Heath two girls meet by chance: well-mannered and smartly dressed Verity and dishevelled and grubby Ruby. Yet the mismatched pair form an instant friendship strong enough to survive their parent's disapproval. When war engulfs the country - sending Ruby to Devon while Verity struggles to find a new beginning under a shadow from her past - the girls are convinced they will always be there for each other. Until the day one breaks the other's heart... Can Verity and Ruby find a way back to each other before it's too late?
