So I'm a closet yaoi fan. I'm addicted to Harry Potter but I think it should have ended differently. I really don't like Ginny or Ron at all but Fred and George are my favorite characters.
I love Dark Harry fics the best. Evil Harry is awesome. I honestly believe that Harry should have ended up in Slytherin.
My favorite slash pairings are:
Harry/Draco, Harry/Voldemort, Harry/Sirius, Harry/Remus, Harry/Severus, Harry/Lucius, Sirius/Remus, Remus/Severus, Dean/Seamus, Harry/Charlie, Harry/ Fenrir, Harry/Bill
For Het pairings: Neville/Luna, Harry/Daphne (if written well)
My all time favorite stories on this site are:
Out of the Night by Raining Ink (no pairing, Harry takes over his life after 5th year, leads a dual life, consorts with Dark Wizards, becomes one himself)
Paradise Lost by Neko-chan -Silvered Tongue (HP/LV pairing, Slytherin Harry, Dark Harry)
They haven't updated in a year but they are awesome.
Completed fics that I love:
Reparations by Sara's Girl (HP/DM pairing post Hogwarts, Healer-in-training Harry, Rehab counselor Draco, crazy coffee concoctions, nosy friends)
Foundations by Sara's Girl (Sequel to Reparations, more drama, Clive (the cutest little boy ever), Narcissa)
Lonely Moon by eleventy7 (HP/DM pairing, Professor Harry, Teddy, werewolf Scorpius, over all cuteness, crazy Ginny)
Black Truth by InferiorBeing (HP/DM pairing, creature Draco, reluctant Harry, drama)
