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.
