New York Times best seller

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.
