Teenage Wen-shan was taken from her family home in mainland China during the Cultural Revolution to live with her great-uncle, a former general in the Chinese army who became one of the first converts to The Church of Jesus Christ of Latter-day Saints in Hong Kong. For ten years, Wen-shan has carried the sorrow of abandonment in her heart, with few memories of her life before. But at the death of Chairman Mao, Wen-shan receives a mysterious wooden box that reveals the fate of the family she has not heard from in more than a decade. Through the letters in the jade dragon box, Wen-shan and her great-uncle discover a bond between each other, their family, and the gospel of Jesus Christ.
