London – 1940 As German bombs rain down upon the city of London, Emma Bradley hastily packs a suitcase, cradles her newborn son in her arms, and boards a train with two evacuee children she's agreed to chaperone in exchange for a job in the south of England. Although she's only one of thousands leaving the city, Emma is fleeing more than the horrors of war. Her greatest fear is that the father of her child will track her down and exact revenge for what she's stolen from him.

World renowned Dutch concern pianist, Andrej Van der Hoosen, is a man who cherishes peace and quiet above all else. His wealth and privilege has afforded him the luxury of avoiding being around children because of a painful loss from his own past. So, when he meets the woman and children he'll reside with for the duration of the war, he's instantly on guard. The children are boisterous and full of life, the cottage they're assigned to live in is small, and he finds himself intrigued by the secret Emma is so clearly trying to hide.

Despite their reluctance to trust each other, Emma and Andrej soon find themselves drawn together in a world torn apart by war.
