Each year, John's late grandfather - the Gaffer - would redraw the boundary lines of the village, with pen and paper, but also through the remembrance of tales and timeless communal rituals, which keep the sheep safe from the Devil. But as the farmers of the Endlands bury the Gaffer, and prepare to gather the sheep, they begin to wonder whether they've let the Devil in after all. From the Costa winning author of "The Loney".
