And when disaster strikes, Mik is faced with a number of tough choices - choices that make him begin to doubt himself and his decisions. Is he making things better or worse for his town? Is he solving the mysteries around him, or is he simply running around putting everyone at risk? Will the voices end up helping him or haunting him?

What is a boy superhero to do?
