Diana Prince is the best. Usually. But these days, she’s coming in second…in history class, in gymnastics, in the race to feed Sir Isaac, the classroom newt. She could double down on training, but when her foe is getting a boost from a mystical mask, will that be enough? No, she will have to rely on her friends to help her combat this newly dangerous menace! Along the way, they’ll discover why so many classmates, family members, and super-villains have gone missing. And why there are so many Cheetahs in the mix!
