As the Second World War draws to a close, Gus Clifton, feared lost in Germany, surprises his sisters at their family home. But an even greater shock is the woman he brings home, Krista - the German wife whom he has married secretly in Berlin.

Gus’s sisters can only see the enemy their brother has brought under their roof. And their friend Nella, Gus’s beautiful, loyal fiancee, cannot understand what made Gus change his mind about their marriage. What hold does Krista have over their honourable and upright Gus? And how can the three women get her out of their home, their future, their England?
