The Last Horcrux (слэш)

Three years after the Battle of Hogwarts: The battle is over, Voldemort is dead, the last Horcrux destroyed, and a new sense of normality is slowly returning to the British wizarding world. But some wounds heal only very slowly, and others seem to have burned themselves into the memory of the world forever. Or into the backs of certain heroes.
