Rory Walker constantly wished for school to be interesting, she's in her last year and nothing exciting has ever happened in that weird and terrifying school. She and her best friend Bex are constantly talking about sinister ideas that could happen in school to make it more interesting. So much they talked that now they have to solve a mystery, survive, betray, and maybe kill other people to get rid of this malevolent specter who will haunt them till it's gone.
