Taking her grandmother’s life as inspiration, the author of the critically acclaimed River of Dust returns with a story set in the dangerous summer of 1937. Widowed American missionary and now single mother Shirley Carson finds herself caught up in the Japanese invasion of North China and the rise of Communism. At first, she finds renewed purpose helping the injured. But as the Japanese take their village, a charismatic Red Army officer requests her help for his soldiers. As other Americans make plans to flee, Shirley must choose: between helping the Chinese Reds by serving as a nurse or escaping the war-ravaged country with her teenage son before it’s too late.
