Disclaimer: If I were JK Rowling, you wouldn't see me posting stories on FFN, and I'd definitely have less grammar mistakes.
Possible parings: Harry/Hermione, Draco/Luna, Minerva/Sirius/Hannah/Tom, George/Tonks (We'll see as the story progresses)
Author note: I was too lazy to make these into chapters so I'm giving you a short summary on what's different between the AU world and the Canon.
Chapter 0: The past
Order of the Phoenix:
Ron is the one who died instead of Sirius at the Department of Mysteries. He is not ambushed by a pair of brains in a jar, Neville is. Ron takes the place of Neville and he rescues Harry from a stray killing curse (shot by Avery), and falls into the veil. Sirius is saved by Lupin, who stuns Bellatrix, and she gets captured together with all the other Death Eaters, including Petter Pettigrew. Voldemort escapes alone. Sirius's name is cleared and he becomes Harry's legal guardian.
Half-Blood Prince:
Dumbledore and Harry's trip to visit Slughorn never happened. Slughorn came to Dumbledore for help, and offered him the memory willingly. Bill and Fleur are not engaged. Harry is depressed over Ron's death and so doesn't take notice of Draco's journey to Nocturne Alley. He refuses to go to Slughorn's meeting on the train. He doesn't keep the Half Blood Prince's book, once he obtains a new one. Neville takes Ron's place in the trio's group along the year. Harry doesn't have his confrontation with Draco in Myrtle's bathroom. Having lived and found the locket in Regulus's room the last summer, Harry realizes the locket is a fake. Dumbledore never drank the potion, but is still killed by Snape.
Deathly Hallows:
Bill announces his engagement with Fleur, which Mrs. Weasley reluctantly accepts. Moody isn't killed by Voldemort since Harry is already living with Sirius. Voldemort takes control of the Ministry of Magic. Sirius and Moody, take charge of the Order. Harry, Hermione and Neville, set of to find the Horcruxes. Luna, Ginny and Draco (whose mother was killed by Voldemort because she was defiant) reestablish the DA at Hogwarts. Harry and Neville retrieve Gryffindor's sword from the lake and destroy the locket. Meanwhile Ginny, Luna and Draco are discovered by the Carrow brothers, who kill Ginny; they spare Luna because her father swore allegiance to Voldemort, but send her and Draco to Azkaban and Lucius is executed. The trio are caught while at the Lovegood's residence and Neville is tortured to insanity by Yaxley. Hermione would have suffered the same fate at the hands of Bellatrix had it not been for Dobby, who takes Harry and Hermione to nr 12 Grimmauld Place (losing his life in the process). Sirius tells them about the taboo on Voldemort's name and that Lupin and Moody were captured and sent to Azkaban because of it. The Order is preparing a rescue mission for those in Azkaban and Harry and Hermione decide to join them. After breaking into Azkaban they find out Remus has received the Dementor's Kiss. They rescue Moody, Luna and Draco, and Fred is killed by McNair. Harry is almost captured by Nott Sr., but Snape kills him and escapes with Harry. They arrive at nr 12 Grimmauld Place, but Harry say's Voldemort's name, while questioning Snape and the Snatchers ambush the place.

They restrain the Carrow and Snape takes Harry, Hermione, George, Draco and Luna to the headmaster's office. Dumbledore tells them about a time turner which could sent them years into the past instead of mere hours, and asks Slughorn to brew a potion that could turn them 11 again. He asks the kid's to go back to Tom Riddle's Hogwarts years and try to change him. Alecto Carrow manages to escape and notifies Voldemort of their presence at Hogwarts. Voldemort arrives and demands they surrender or face the consequences. And the story begins!
