The premise is simple: That last kids anyone would expect are abducted to serve as surrogate children to a childless heiress nobody would ever suspect. The fact that they are eight kid super heroes with incredible powers aside, the problem I'm having is their ages. Right now I have seven of them at twelve with an eight year old little brother completing the team. Thinking about the first "Harry Potter" film, I got to wondering if the the kids may be a bit too young. Harry and the others were eleven and didn't exactly exhibit an aire of maturity and confidence I want my heroes to project. At twelve, they aren't that much older. I just wonder if I should make them say thirteen or fourteen and if that would make them too old for the plot? Any suggestions?
