Two sisters and their grandmother celebrate a popular Chinese holiday with family. Their favorite part? Mooncakes, of course—along with Ah-ma's story of the ancient Chinese tale of Hou Yi, a brave young archer, and his wife, Chang'E. A long, long time ago, Hou Yi rescued the earth from the heat of ten suns. The Immortals rewarded him with a magic potion that could let him live in the sky with them forever. But when a thief tries to steal the potion, what will Chang'E do to keep it out of dangerous hands? The sisters are mesmerized by Ah-ma's retelling and the fact that the very mooncakes they enjoy each holiday are a symbol of this legend's bravest soul.
