The apocalypse strikes in the middle of ninth grade, and a zombie horde crashes through the calm of the schoolyard. Three troublemakers hold up the sky over Class 1107: skipping class and getting into fights are their daily routine, but protecting their classmates comes naturally. No one expects the zombies to evolve far faster than the boys’ fists. Mutated fangs draw near, and their classmates’ lives are at stake. The least heroic people imaginable have no choice but to grit their teeth and fight to the bitter end.
