Our hero, Don Wallace, is a wide-eyed new boy from a modest background, forced to navigate a baffling new world of arcane rules and rituals, presided over by sadistic sixth formers. Matters of status are aggressively enforced and conversation with school goddess Clemsie, strictly forbidden. But this ancient and ordered world is about to be shaken to its foundations - literally. A controversial frack site on prize school woodland causes seismic tremors, a mysterious sinkhole and an unspeakable horror to be unleashed. Soon a new pecking order will be established as pupils, teachers and the school matron become locked in a bloody battle for survival.
