I was in the middle (I think) of reading a HP/DM fic on AFF, but I can't find it anywere.
I started it some years ago (as in maybe 10...!) and I saved the first 11 chapters to my computer, because I think I might have been supposed to beta it... my memory just doesn't go that far back, so I have no clue...
The story is/was called "Harry's Universe" and is/was written by some one called BGW.
Harry is severely mistreated by the Dursleys (as in starved, beaten bloody, raped...) and he finally manages to escape from them.
He goes to Muggle London and somehow gets his hands on a paper bag with a small bag of some drug or other (might have been heroin), a syringe and a little note that tells him how to use the drug.
The drug makes him feel good, no pain - mentally og physically - and of course he gets hooked.
He gets his stuff back from the Dursleys, and goes to Hogwarts. While on the train he manages to take more of his drug, and he's so out of it, that he starts masturbating - and spunks Draco in the face.
When they all arrive at Hogwarts, they are told, that because there's so few of them left, everyone will be resorted, and Harry ends up in Slytherin.
This turns out to be really good for him, because the Slytherins accept him (maybe because Draco admits to them that he loves Harry), and they all try to help him beat his addiction.
Harry, Draco, Ron and Hermione goes Horcrux-hunting and they go to Godrics Hollow to find Lilly and James' old house. Here they find James' wand, which turns out to be a Horcrux that only Harry can touch without getting burned.
One night Harry gets an overdose when someone drugs him, and he goes into a coma for several months.
The culprit turns out to be Percy Weasley, who has joined Voldemort.
One day Harry suddenly collapses and goes back into a coma-like state, and he is in training with Dumbledore...
That's the last thing that I have, but it says "TBC" and you can't just leave it there...!
It's a pretty good story, and I really want to read the rest of it - I hope someone here can help me find it!
It might not have the same title anymore, or the author might have changed her name as well, but who knows?
