Fourth-grade superhero Jo Schmo doesn’t know that a crime wave is about to hit her city. She’s too busy learning new superhero skills, like shape-shifting. Only it doesn’t seem to be going very well: what bad guy is scared of a superhero that looks like a frizzy-haired teacher? But Jo and her loyal doggy sidekick, Raymond, know they have to stop the villainous Numb Skull before the crime wave builds into full-on crime tsunami. And if that means Jo has to risk shape-shifting into a freckled monster, then that’s just what she’ll do!
