Nineteen-year-old Joy Louie has run away from her home in 1950s America to start a new life in China. Idealistic and unafraid, she believes that Chairman Mao is on the side of the people, despite what her family keeps telling her. Meanwhile, Pearl returns to China to bring Joy home - if she can. For Mao has launched his Great Leap Forward, and each passing season brings ever greater hardship. Pearl must use her contacts from her decadent childhood in 1930s Shanghai to find a way to safety, and a chance of joy for them both.
