Ragesong

When the peaceful kingdom of Fermicia is enslaved by a power-hungry renegade, its only hope lies in a band of unlikely heroes: two children whose musical abilities allow them to harness the power of Ragesong, and their shape-changing guides. Jake starts his first day of junior high completely oblivious to the fact that he has been chosen for something incredible. That same afternoon, he learns that he has been marked as one with the power to save an entire kingdom. Through the course of his journey, Jake discovers that his advanced musical abilities are peculiarly connected to a mysterious power known as Ragesong. Joined by a shy, young girl with similar musical talents and two Changelings that hold a fierce loyalty to their homeland and king, Jake must learn to harness this ability in order to survive the dangers of a hostile new world.
