Before Victor can figure out why Benjamin Franklin awoke from his two-hundred-plus years of sleep, giant bat planes and mysterious attacks bring mayhem to Philadelphia. Only two of history's inventors could pilot such high-flying creations--the famous Wright brothers! But the red-eyed brothers don't seem quite like themselves . . . could the brothers really want to take over Philadelphia--and can Victor and his friends crash their plans in time?
