This expertly crafted novel, full of rich details about Chinese culture, focuses on four women, best friends, living in San Francisco who form a club to play mahjong. The women are Chinese immigrants; their daughters are American. The book begins with the death of one member, Suyuan Woo, who dies without being reunited with the twin girls she was forced to abandon in China after the second world war. The other women, the “aunties,” ask Suyuan’s American daughter to take her place in the club. At the first meeting, they tell June her long-lost sisters are alive. They’re going to give her money to go to China and fulfill her mother’s greatest wish. They want her to tell her sisters about the mother they never knew. But June feels she never knew her mother, either. All the aunties have wisdom to pass on to their independent American daughters, but the cultural divide is wide. June is finally able to finally make peace with her mother when she meets her half-sisters and fully embraces her Chinese heritage.
