There once was a lady who was very creepy. She moved about the world in seemingly normal ways, except for one tremendously bizarre tic. First she sought out kids transfixed by their screens, staring blindly and blank-faced at nearly any device, and then she would snatch something precious from them. In this picture book for grown-ups, sibling duo Keiler Roberts and Lee Sensenbrenner render a compelling—and downright creepy—modern fable about kids who are hooked on their digital devices.
