What if your planet was massacred and you were the sole survivor?
What if a legendary figure out of space and time found you a place to hide?
But what if the things that want to kill you have tracked you down?
And worst of all, what if you haven’t studied for your A-Levels…?
Coal Hill School has been a part of the Doctor Who universe since the very beginning, but that has come at a price. 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.
