"Zach King's life has turned upside down! Since he's finally recovered his magical powers, middle school has never been better for Zach--he's teaming up with his best friend, Aaron, on their super-popular YouTube channel and talking to the prettiest girl in school, Rachel. But when Zach collides with a magical mirror, he lands in a world that is the exact opposite of everything he's ever known. Instead of finding himself at Horace Greeley Middle School, he's at Horace Greeley Magic School. . . In this world of opposites, everyone has magic except him. . . Even worse, while Zach is stuck in this world, his magic-world double, Jak, has swapped places and is getting into all sorts of trouble in Zach's world. Fortunately, Zach can always count on his friends--even the magic-world versions of them. If he can just convince Baron and Raquel about the truth of his world-jumping misadventure, Zach knows they'll be able to figure out how to get him back to his world before it's too late"--Provided by publisher.
