Until she senses an unusual energy like a human shaped void in the universe. When Penny investigates the source, she gets tossed through a crack in time along with the cute boy next door. The Void follows them through history, increasing the dangers as if testing Penny. But what is it testing for? And why does it claim to know her better than even she knows herself? Even as Penny searches for answers, she must fight to survive the tragedies of both the past and future in order to get back home.
