Doctor Who: The Twelfth Doctor Vol. 2: Fractures - Morrison, Robbie

The Doctor and Clara have returned to 21st Century London. But there's something not quite right. Something unsettling, in-between the cracks in the pavement and the holes in the wall. Impossible creatures dragging themselves in from the Void on the back of an experiment from a parallel universe. The Fractures are here... and they're Hungry.
