Dead Zone meets Sixth Sense when a girl learns that a boy in her class will one day launch World War III. Can she kill his still-innocent self today in order to save millions of lives tomorrow?

"What I know: a boy in my class will one day wipe out two-thirds of the population with a virus. What I don't know: who he is. In a race against the clock, I not only have to figure out his identity, but I'll have to outwit a voice from the future telling me to kill him. Because I'm starting to realize no one is telling the truth. But how can I play chess with someone who already knows the outcome of my every move? Someone so filled with malice they've lost all hope in humanity? Well, I'll just have to find a way--because now they've drawn a target on the only boy I've ever loved..."-- Publisher's description.
