Mo and Jo love the same superhero—but can't stand each other! Mona and Joey can't stop fighting! When the Mighty Mojo decides to give his powerful costume to them, these argumentative twins fight so much they rip it in half. Now each one is only half as strong! Can Mo and Jo find a way to combine their powers, fight the evil Saw-Jaw and save their town? Two master cartoonists, writer Jay Lynch and artist Dean Haspiel, create a loving, tongue-in-cheek superhero tale where the kids' biggest battle is just learning to get along.
