Millions of years have passed since our three worlds were separated. Our planet is not alone... it is bonded with two others. Long ago the twin planets, Pairetoria and Untoria, fell away from our shared sun, fleeing in fear of a dark event in our world's future. They have not been heard from since. But they are still out there. And they are about to reach out to us again. One means us much good... the other seeks to do us devastating harm. Which will prevail? The deciding factor is a musical boy named Aidan, who is much more than he appears. With his narrative friend at his side, Aidan will embark on an amazing journey, visiting both the other worlds and encountering everything from dragons to soul-shattering demons... and even becoming a dragon himself. He will discover that planets are living things too, and that his drive to create music may be exactly what he needs to save us all.
