My take on the classic "Harry meets Hermione first," trope.
Harry Potter is back in time at the end of his third year at Hogwarts. The list of people he trusts is short, and he knows how badly things can go, but he doesn't know where all the Horcruxes are. He's broken, and he's been charged with saving the world.
At the Yule Ball, Harry finds the courage to speak his mind to Ron. Some things change. two-shot, not Ron-bashing.
Hermione asks Harry for helping learning to break the Imperius Curse. Truths are spoken and forgotten. ONESHOT. COMPLETE.
Harry Potter is a geek, a nerd, a total dork whose favorite hobby is "transfiguring stuff." He doesn't understand what rules are, has no social skills, is barely sentient, and is very smart.
The power Harry knows and Voldemort does not. Oneshot. COMPLETE
Seeing as he's her closest living relative who isn't her mother, a Malfoy, or a prisoner of Azkaban, seventh-year student Nymphadora Tonks takes first-year student Harry Potter under her wing. Possible Harry/Tonks when Harry's older?
Creeped out by all the tombstones, Harry and Cedric leave the graveyard almost as soon as they arrive. As result, much is different. Not sure of pairings.
The Great Firebolt Debacle of Harry's third-year shakes out differently, and the whole year is affected. H/Hr. Mild Ron bashing.
Harry and Hermione seek to avert Armageddon by altering a small but oddly impactful moment.
Harry survived Voldemort's curse because his parents were badass magic researchers.
Harry can't date until Voldemort is defeated. Harry/Luna
