Back for the First Time, Harry?

After a night of typical teen revelry, Harry wakes up with a hangover and a choice. Maybe he would've chose differently if his head wasn't killing him but it's too late now- it's 1974 and he's a pipsqueak again. The Knights of Walpurgis are making waves in the political arena... while in the shadows, a mysterious character that goes by the name Lord Voldemort is seeding revolution.
