All the time travelling over the years has caused the very walls of space and time to become thin. There’s something pressing in on the other side, something waiting for its chance to kill everyone and everything, to bring us all into Shadow. Four Coal Hill School sixth formers will face their own worst fears, navigating a life of friends, parents, school work, sex, sorrow and possibly the end of existence.
