When lightning strikes there can only be trouble - as Jess Mastriani finds out when she and best friend Ruth get caught in a thunderstorm. Not that Jess has ever really avoided trouble before. Instead of cheerleading there are fistfights with the football team and month-long stints in detention - not that detention doesn't have its good points - like sitting next to Rob - the cutest senior around! But this is trouble with a capital T - this trouble is serious. Because somehow, on that long walk home in the thunderstorm, Jess acquired a newfound talent. An amazing power that can be used for good... or for evil.
