When the news starts reporting a zombie outbreak in Ireland, B's father thinks it's a hoax-but even if it isn't, the two of them joke, it's only the Irish, right? That is, until zombies actually attack the school. B is forced on a mad dash through the serpentine corridors of high school, making allegiances with anyone with enough gall to fight off their pursuers. But when they come face-to-face with the ravenous, oozing corpses, all bets are off. There are no friends. No allies. Just whatever it takes to survive.
