Harry Walpole knows something weird is going on: His palms sprout hair, his teeth grow into fangs, and he heads for McDonald's every time there's a full moon. Could he be...a werewolf? Looks like it runs in the family, and Harry's the next victim. The curse isn't easy to shake (who wants to get shot with a silver bullet?)-- but Harry Walpole, werewolf, has to find a way to turn back into Harry Walpole, third-grader, before his secret embarrasses him in front of everybody.
