Music gives us life, and we give life back to music. In a world very much like ours, there exist people who can wield the sound of music in ways both fantastical and terrifying. Since the dawn of the Classical period, these people have called themselves Music Masters. Centuries later, and one disco-loving teenager named Michael Kay would discover himself to be one of those very same special few. Trials and tribulations, friends and foes: these all await Michael in the musical adventure of a lifetime, as he figures out what it means to truly be a Music Master.

High school student Emma thought senior year would be unremarkable until she meets her new neighbor and classmate Joe. She soon discovers he has otherworldly powers. He confides that he's an alien from another planet, much more advanced than Earth. Most humans are unaware of their existence due to their ability to manipulate time. Joe informs her that her father was the King of their planet, which makes her half-human/half-alien, or a hybrid, and the next in line to be Queen. He has been assigned to protect and bring her back to their planet where she will be coronated as Queen. Without her, the universe will be on a path toward destruction. All of Earth could be wiped out without her leadership. Emma's senior year is about to get much more remarkable indeed.
