Here comes trouble. In Zodia, an island comprised of 12 Kingdoms all ruled under the same monarchy, there is a tradition. Every fifteen years the Queen's protectors, a group of powerful warriors known as the Zodiacs, are replaced. Being a Zodiac doesn't just come with power and responsibility, it is also fame and fortune. As the current Generation of Zodiacs approach their thirteenth year of service, it is time for the Queen to select a new Generation to begin their training. Now enter The Class: a group of thirteen mismatched troublesome high-schoolers who definitely wouldn't be anyone's first pick to defend the Queen. They're cunning, obnoxious, difficult, have terrible habits and sure as hell don't respond well to authority. Everyone in Zodia's high-school knows who you're talking about when you mention 'The Class'. It's the class at the very back of the building. The class with paint on the door and a smashed in window. The class that forced three teachers to quit. The class that is really just a permanent detention center. So what happens when the Queen decides they're going to be Zodia's next Generation of heroes? All hell breaks lose.

The zodiacs are living as roommates as they navigate their daily lives together.

At the prestigious Zodiac Academy, twelve 18-year-olds from each of the zodiac signs are trained to harness their unique powers, preparing them for the ultimate responsibility-guarding the balance of the universe. Amidst spell-casting lessons, enchanted sports tournaments, and school traditions, unexpected love begins to bloom. But love isn't the only thing they'll be battling. Ophiuchus, with its dark and mysterious powers, threatens to shatter the academy and the very fabric of the zodiac itself. The students must put aside their differences and combine their strengths to stop the evil force from consuming everything they've worked to protect.
