Di Di is leaving to spend a year in China with his grandparents and extended family, but Sharon and middle sister Mary aren’t so sure about that. A year is a long time, and they miss him at first, but then get busy with their own lives. When Di Di returns, it is a difficult adjustment for everyone.
I actually was familiar with this idea through friends of mine, who lived in their family’s country of origin from the time they were weaned until preschool and then flew back each year to live there over the summer. However, for many readers it will be new. This topic is also briefly explored from a different perspective in American Panda. In that book, the father decided to send the children to his family in China against their mother’s wishes, and it was challenging for the family.
