Waking up on a subway car you can't remember getting on? Harsh. Being chained to your seat with no clue where you are headed? Even worse. Sitting across from a beautiful girl on the train ride to hell? Maybe this won't be so bad for Ashe Edwards. Unfortunately, when the subway doors are opened by a bizarre group of teens, he finds himself in an abandoned town filled with eerie mannequins on every corner, surrounded by a forty-foot-tall electric fence, and ruled by hormonal ideals and convictions. As if that wasn't enough, Ashe learns he will be forced to fight for his life each week against waves of military-grade war machines, dropped into their prison by an unknown captor with the sole purpose to kill everyone in sight. However, these wayward teens are not as helpless as Ashe first assumes. Each prisoner has been equipped with a weapon or ability, surgically implanted into their body by their captors. Ashe must discover and master his ability and work as a member of a team of eccentric and reckless captives, called the Black Birds, if he doesn't want to end up dead like countless others before him.
