Ever since a walk home on a particularly stormy day, Jessica Mastriani has had an ability like no other. She became known worldwide as Lightning Girl—a psychic who could find the location of anyone, dead or alive.

But her work for them has taken a terrible toll, and Jess resurfaces months later a shadow of her former self, her powers gone, Lightning Girl no more. Her only hope is starting over in a new place, a big city where nobody knows her. It's only when Rob Wilkins unexpectedly shows up on her doorstep that she's forced to face her past. Rob, all the way from back home, needs her help. But how can Jess, her powers gone, find anyone, let alone the sister of a man she once loved... when she can't even find herself?
