When twelve magical superpowers are unleashed on the world, a Chinese-American teenager named Steven will be thrown into the middle of an epic global chase. He'll have to master strange powers, outrun super-powered mercenaries, and unlock the mysterious powers of the Zodiac.

Steven Lee, fifteen-year-old leader of the Zodiac team, wields the awesome power of the Tiger—but now he's missing. So when a high-speed train runs amok in France, it's up to the other members of the team to stop it: Liam, the powerful Ram; Duane, the Pig, who controls information; and Roxanne, the fierce Rooster, with her unstoppable sonic power. But can they trust their new member—the former villain called Ox?

It’s a heavy-metal battle royale when Maxwell—head of the Vanguard organization with the evil powers of the Dragon Zodiac—sends an army of robots against Steven Lee, the teenaged Tiger, and his team. Using their new and mysterious powers of the ancient Zodiac, Steven and his teammates must work together like never before to defeat the robotic invaders!
