China, December 1941. Having left an unhappy life in England for a teaching post at a missionary school in northern China, Elspeth Kent is now anxious to return home to help the war effort. But as she prepares to leave China, a terrible twist of fate determines a different path for Elspeth, and those in her charge. Ten-year-old Nancy Plummer has always felt safe at Chefoo School, protected by her British status. But when Japan declares war on Britain and America, Japanese forces take control of the school and the security and comforts Nancy and her friends are used to are replaced by privation, uncertainty and fear.
