John is like any other teenage boy, except for the fact he was born invisible. Thanks to his father’s freak experiment, he’s a ghost hovering in the midst of a visible world.

Right at the height of the war, two mechanical soldiers show up on the home front looking for the boy no one has seen—and use him in a battle he doesn’t want to fight.

After John flees to a world where no one knows he exists, one young girl discovers who he is and convinces him to stay. But when his father and the mechanical men catch up to him, he must decide between the visibility he’s always longed for and the friendship of the one person who’s ever truly seen him.
