Family is important to Hua Mulan—even if her parents don't understand why she would rather ride her horse, Black Wind, than weave, or how her notorious clumsiness can be so different from the graceful demeanor of her younger sister, Xiu. But despite their differences, Mulan has a deep love for her family, especially Xiu. So when her sister is bitten by a poisonous spider, Mulan does everything she can to help, including seeking out a renowned healer. However, it quickly becomes apparent that there is more to both the mysterious spider bite and the healer than meets the eye. On a quest with the Jade Rabbit of legend, Mulan visits extraordinary places, meets Immortals, and faces incredible obstacles while searching for an antidote for her sister. And the danger only rises when Mulan learns of a prophecy foretelling that a member of the Hua family will one day save the Emperor . . . and of the powerful enemies who will stop at nothing to prevent it from coming to pass.
