Twelve-year-old Aronade plays a lot of games, but they aren't games of her own design. These games have been crafted by a man who goes by the name, "The Instructor." He creates these mind games called scenarios in order to teach Aronade "lessons" about how the world truly operates. But when Aronade discovers a nearly drowned teenage boy from the outside world at the compound, she soon discovers that the Instructor's games may not be so harmless after all. In fact, they may be deadly.
