Relentless - A Dramione FanFic

The war has ended. The golden trio were able to enjoy a rather normal summer holiday. Other than the month spent tracking down Hermoine's parents and restoring their memories, things were relaxed, comfortable, perfect, even. But they were headed back to Hogwarts for the 7th year they never had, and they knew better than to expect a completely smooth ride... hope, yes. Expect...Never. What they didn't anticipate was who else would return, and how he would tip their world upside down.
