Black Chalk - Christopher J. Yates

One game. Six students. Five survivors.It was only ever meant to be a game. A game of consequences, of silly forfeits, childish dares. A game to be played by six best friends in their first year at Oxford University. But then the game changed: the stakes grew higher and the dares more personal, more humiliating, finally evolving into a vicious struggle with unpredictable and tragic results. Now, fourteen years later, the remaining players must meet again for the final round.
