A/N: Obviously the Harry Potter universe and the majority of characters do not belong to me. What do you expect when reading stories on a website called " " in any case?

I love this pairing for some reason, so am attempting to write a long time travel fic about it. I owe some of my ideas to other brilliant fan fiction writers, as well as J.K. Rowling.

Prologue

It is extraordinary how one single, silly action can change the entire course of not only the present, but also history. This action, or lack thereof, took place on a riverbank far away from Hogwarts School of Witchcraft and Wizardry. Harry Potter, Ron Weasley, and Hermione Granger, tired and disheartened after a long day of searching fruitlessly for places Tom Riddle may have thought to hide his horcruxes, forgot to cast a certain protective charm around their tent.

At this very point, one universe split into two.

In the one universe, you may be glad to know, nothing came of this minor mistake, and Harry, Ron and Hermione left the next morning without even noticing they had been partially unprotected. They went on to find and destroy all the Horcruxes, and Harry eventually defeated lord Voldemort at the Battle of Hogwarts.

In the other universe, Ginny Weasley had nothing left to live for, as her ex boyfriend, her brother and her best friend had been discovered by snatchers in the night and killed without even being taken to lord Voldemort first.

But Albus Dumbledore, the most brilliant wizard of the century, was nothing if not a good planner. He would never lack a backup plan, and this time, Ginny Weasley was to carry it out.

This was why four o'clock on an autumn afternoon,Ginny Weasley was to be found rushing down corridor after corridor heading for the headmaster's office. The rays of late afternoon sun coming through the wide windows she flashed passed caught the long red hair flying behind her, making it appear to be set aflame. In her, hand she held a single delappedated suitcase.

"Dumbledore!" she barked at the gargoil in front of what had once been Dumbledore's office, and sped up the moving staircase without waiting for it to carry her to the top. She knocked urgently at the griphin doornocker, and entered when she heard the voice of professor Snape answering from inside.

"Weasley," professor snape stopped pacing up and down behind his desk and faced Ginny. You are packed and ready I see."

"Yes Sir," said Ginny.

Only a few, short, agonising days ago, Ginny had learnt that her ex boyfriend, her brother and her best friend had been killed in their sleep by a group of snatchers on their mission to destroy lord Voldemort. Apparently they had wished to win Voldemort's favour, but Ginny felt that it couldn't have pleased him that someone other than himself had killed Harry Potter. She also learnt that Snape had always been on Dumbledore's side and that the latter's death had been planned between them. As if all this news had not already turned Ginny's life and everything she thought was real up side down, Snape had told her an hour ago that Dumbledore had had one last plan to save the wizarding world if Harry, Ron and Hermione were killed on their quest. She, Ginevra Weasley, was to go back in time to 1943 and prevent Tom Riddle from ever becoming lord Voldemort. How she would do this, she did not know, but on hearing this plan, she had desperately agreed. Perhaps her grief over the deaths of three people she loved

fiercely had made her wreckless, but she could no longer remain in a world where they had died, and for nothing, at that. She supposed she would have to kill Tom Riddle, which would be a difficult task, but she had been the top fighter in the DA after all. Snape had told her that the reason that she, Ginny Weasley, was chosen as the girl who would carry out the task was because she had the most experience with the teenaged Tom Riddle after Dumbledore, and she partly understood him, even if he had lied to her through the diary.

"You will take this letter to professor Dippet," said Snape, producing a manilla envelope. "It will partially explain your situation, with no mention of your actual task, of course. "And this one," he added, producing a white envelope, "you are to give to professor Dumbledore from his future self. You will introduce yourself as Ginevere O'Shara, an Irish exchange student. The O'Sharas are a pureblood family of travellors, but you will not meet any of them at Hogwarts in 1943. There were known to homeschool their children. Ginevere is also a name that has been passed down through generations in that family. You will restart your sixth year there."

Ginny had never been gladder that she had spent some time with Seamus Finnegan whilst she had been dating Dean Tomas. She had learnt to mimmick his Irish accent a little. At least, she hoped it would be passible.

"You will be sorted into a house," continued Snape, "And you will be in sixth year, as you are now."

Ginny gulped. "Yes Sir."

"Time turners are not ment to send people forward in time," Snape sneered slightly, and Ginny was reminded of the fact that, despite his loyalty to Dumbledore, he was still a rather unpleasant person. "You will probably not be able to get back when you have done your duty. Attempt to assimilate."

"There's not much left for me here anyway," said Ginny dryly, as she put the chain around her neck.

"Fifty three turns, Weasley; this particular time turner is used to go back in years, not hours," said Snape as if he hadn't heard her.

She started to turn the little hourglass, and watched the world around her melt into a blurr of different colours. Just before the tall, bat-like figure before her disappeared for good, she could have sworn she saw his lips form the words, "good luck".
