But Henry and his friends quickly discover that their professors have made some troubling changes to the curriculum -- an old classroom filled with forgotten weapons. It is the discovery of this classroom that prompts Henry and Valmont to become the unlikely leaders of a secret battle society. But disaster strikes as Henry, Adam and Frankie find themselves stuck as Partisan School servants. Yet something is rotten in Partisan Keep. And when Henry is discovered by a secret society of outlaws with a sinister purpose, he must come to terms with a great sacrifice that will take him away from everything he has ever known and wanted.
