Twelve-year-old Summer McKenzie discovers that her life is going to be crazy...well, crazier than it used to be. She experiences a revelation that the Zodiacs affect her powers and her new house, and soon, a mysterious figure appears on her windowsill, asking her to go to a whole new world called the 'City of Magique'... but that is the most normal thing that has ever happened to her. And that's how she ends up in a school named 'Crystaina High' for some special students who, though unlike her, will soon become close to her.

Confused and perplexed, she stumbles upon a dark secret that was buried long ago—a tiny pearl, that could bring them either an immense win or a brutal loss. While she and her companions, Lucas and Blythe, try to get their hands on it, they are yet to fully understand that they are up against an evil so terrifying that the entire city trembles at the mere thought of it. Little does she know about the struggles she would have to endure and the dangers that await her...
