Reciprocity's Fallacy

It is four years after the Battle of Hogwarts, but in many minds the war is still far from over. Not all is well in Post-Voldemort Britain and as the struggling Wizarding society tries to rebuild itself, and a trend in pureblood killings is uncovered. AU, follows canon up until Battle for Hogwarts. No bashing, dark tone, mature themes, some romance and humor. Gritier Harry.
