Yu-ning thinks her perfect life on Rainbow Island will never end-until a nasty dragon called the Obsidigon returns from beyond the grave. Now her beloved island is in flames, her best friend has been kidnapped, and the island€s Sacred Crystals have been stolen. To make matters worse, she must venture into the dark corners of the world to uncover secrets best ignored, find a weapon thought long destroyed, and recapture seven sacred stones-without being burned to a crisp by a very angry dragon.
With the help of her master teacher, Metatron, Yu-ning embarks on a dangerous journey to overcome not only the darkness attacking her home, but also the scars of sadness that mark her own heart. And while most people just see a normal kid, Metatron-and a few other unlikely allies-pledge their lives to the dark-eyed little girl with a magic bow and a crooked grin.
