Nineteen-year-old Na has always been in the shadow of her younger brother, Bao-bao, her parents' cherished son. When they were younger, Na's parents went to work in the city, bringing Bao-bao along and devoting all their savings to his education, while Na was left behind in the countryside. But when Bao-bao dies suddenly, Na realizes how little she knew him. Did he really kill himself because of a low score on China's all-important college entrance exam? Na learns that Bao-bao had many secrets, that in his own way he struggled with their parents' expectations as much as she does, and that his death may not be what it seems.
