Twelve-year-old Elliott Harkness wants nothing more than to join his family as part of the Freedom Force, the world's greatest superhero team. There's only one problem, he's a "Zero;" that's super-speak for powerless. Frequently abandoned by his crime-fighting family, teased by his older super-sister, and picked on at school, Elliott is miserably ordinary in his heroically extraordinary family. All of that changes when a mysterious new girl comes to town. She believes Elliott is far from ordinary.
