There was rarely a time when Phoenix Yuan-Whyller's mother, Rain, didn't live with her. Even when Phoenix got married, Rain, who followed her from China to Toronto, came to share Phoenix's life. Now at the age of 83, Rain's unexpected death ushers in a heartrending separation. Struggling with the loss, Phoenix comes across her mother's suitcase - a memory box Rain had brought from home. Inside, Phoenix finds two old photographs and a decorative bottle holding a crystallized powder. Her auntie Mei tells her these missing pieces of her mother's early life can only be explained when they meet, and so Phoenix boards a plane for China. What at first seems like a daughter's quest to uncover a mother's secrets becomes a startling journey of self-discovery. Told across decades and continents, Zhang Ling's exquisite novel is a tale of extraordinary courage and survival.
