A reclusive old man had to die before something of major proportions happened in the small seaside town of Calder Cove. Then, after a series of weird and rather extraordinary events a strange and mysterious castle is revealed - a castle that seemed to have appeared out of the darkness and silence of nowhere. Was it magic? Or was it something more sinister. In time, it is made known that the massive grey edifice is nothing beyond a school, but when the exclusively invited children finally step inside, the huge doors are locked securely behind them. They are then thrown - without warning - into the unknown. It is with great trepidation that they begin to question this, asking … is this place really a school? An answer to their dilemma begins to show itself after an intriguing visit to an Aztec pyramid that ends with the theft of a cursed ring, and the eventual disappearance of the school's bully, Neville Cormac. When some students ban together to look for him they stumble upon magical rooms and hidden passageways, a golden door and … most horrifically … their own doom!
