The #1 New York Times and USA Today bestselling Wings of Fire series continues with a dragon world finally at peace -- until a new prophecy warns that an ancient evil could rise again . . .

Peace has come to Pyrrhia . . . for now.

The war is finally over, and the dragonets of destiny have a plan for lasting peace: Jade Mountain Academy, where all tribes are welcome to live and learn together.

Even at the new school, though, secrets abound. Moonwatcher is hiding her ability to read minds; confessing that she holds this long-lost NightWing power will only cause trouble. But it also gives her access to another secret: the thoughts of a different mind-reading dragon, one who might be a friend . . . or a terrible enemy.

Then someone starts attacking the school, injuring dragonets and frightening everyone. Moon knows she can use her powers to help. But is revealing her secret the most dangerous choice of all?
