The Ginger Tree by Oswald Wynd

In 1903 Mary Mackenzie sails for China to marry the British Military Attache, a man who turns out to be every bit as chilly as the Peking Winter. During one of his many absences, Mary has an affair with a Japanese soldier, Count Kurihama, but her pregnancy is impossible to keep secret. Rejected by husband, mother and country, and forced to leave her daughter behind, Mary flees to Japan.

The Ginger Tree tells the fascinating story of her survival, isolated and alone, in this alien culture.
