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 parents' 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?
