There is an ancient Chinese belief that an invisible, unbreakable red thread connects all those who are destined to be together.
A king and queen rule a beautiful and peaceful land. They should be full of joy and contentment, but they both feel a strange pain that worsens every day.
Then a peddler's magic spectacles reveal a red thread pulling at each of their hearts. The king and queen know they must follow the thread-wherever it may lead.
Grace Lin's lovely adoption fairy tale is for all children-and the parents who would search the world to find them.
