A/N I'm back! This is a story that has been filling my head lately and I had been wanting to get back to writing for a long time. Its a time travel story, mixed with a little bit of romance. I have been intrigued with the Harry/Katie stories that I have read lately so I decided to take a crack at it.

This story is A/u but the only things that differ from cannon are the things stated below. Cannon probably won't be followed in the rest of the story at all so sorry if this isn't your thing.

As always, I do not own the rights to Harry Potter. They belong to the brilliant J.K Rowling and I just happen to do this for fun!

P/S It would be nice to get some reviews for this. Lol.

"So your finally going to be a man today Potter? You're going to face your death? Timely isn't it? You're a Gryffindor, but yet you're a coward. Countless good people, people that "loved" you have died because you wouldn't come out of hiding. Poor Ginny Weasley, I tortured her for hours before her mind broke, she was a fool just like you."

"Shut up!" Harry screamed loudly tossing and turning as he slept, painfully reliving his darkest days.

"Her mother and father were the same, loyal to you until the very end, never giving up any information on your whereabouts. I admit I was frustrated, I didn't mean to kill them so soon."

"No!" Harry shouted, flipping violently to his other side. It was at that moment that she decided to wake him up. He must have forgotten to take his dreamless sleep potion.

"It was a great surprise when Ron showed up. He was angry. It wasn't his fault he died really; he had walked in on me killing his parents and his little sister. He earned his stripes though, he wasn't a coward like you, he tried to fight."

"Ron…" Harry choked out weakly. He was crying now, and their bed was soaked with the sweat that was pouring out of his pores like rain from the clouds, and she tried to shake him awake, tried to call his name. Nothing was working

"Then finally that filthy mudblood Hermione. While you faked being dead, she tried to fight me. She was so angry; I had taken everything from her. Bellatrix killed her with ease, just like she did your godfather."

She ran to the kitchen and filled up a cup with water, hopefully that would wake him up.

"You have lost everything Harry Potter. Avada Kedavra"

He sat straight up, eyes fully open, mind fully aware of his surroundings. He noticed his wife carrying a cup of water, which she dropped and ran over a crushed him with a hug. It made him a little sad, knowing that today was the day. She wouldn't see him after today anymore, but technically she wouldn't exist in her current state because none of this would have ever happened.

"You have got to remember to take your potions Harry" she told him as she lightly kissed him on his lips.

He nodded slowly and got up to stand next to the window. He would definitely miss this about Katie; she always was so loving and caring. After the war and everything was over she helped him cope with the loss of his friends, just like he helped her with the loss of hers. They never got married or had any kids, but he had grown attached to her and couldn't imagine life without her. Maybe this time, this time he could give her a proper life.

"Look the sun is rising" he said softly. It was beautiful, just like she was. Mark that on the list of positives about going back, he would get to fall for her again, hopefully she would fall for him again too.

She went to stand next to him, holding him in a tight embrace as they watched the sun rise above the darkness together. Harry sighed heavily, he wasn't going to tell her his plan, and truth was that he was actually planning this from ever since he killed Voldemort in the first place. Katie just kind of came up and threw a wrench in all his plans. Never in a million years would he think that he would be able to love again, ironic the thing that Dumbledore said was his greatest strength, turned out to be something he wasn't able to do for a long time.

Then she came along, broken and battered just like he was. Angelina and Alicia, her own best friends, were murdered in the final battle. Her mother and father tortured for information just like the Weasleys. Somehow, they had found comfort in each other's sorrow, somehow they found happiness.

He could save them, he could save them all. Ever since the war was over he was doing research on time travel and he, along with the other Unspeakables, found a way to send his mind back using the brains that once attacked Ron so long ago. Before that, they found a way to send a person's body back but that wasn't good enough for Harry. He did however take advantage of it.

With the help of an expensive test subject named Trevor Bacon, he had to pay the kid 200,000 galleons which was chump change compared to what the minister gave him for the war, he was able to send back loads of money, books, and evidence that Trevor buried in the Dursley's back yard. Now, he had everything needed to change the world because in the end, his goal wasn't only to save his and Katie's friends.

"I have to go to work soon" Harry whispered as he softly ran his fingers through her hair. He didn't want to wait too long, or else he would probably get cold feet. She didn't say anything; she just nodded, but kept her hold on him. He waited until she let go, and walked into the bathroom to take a shower and get dressed.

He walked slowly toward the door, where she was waiting for him with a smile. She hugged him one last time, and gave him a light yet passionate kiss.

"Promise you will always love me Harry" she said suddenly, it was almost like she knew that it was the last time she would ever see him again.

"Until the end of time."

It had taken them thirteen years to finish this project. They had found out through a lot of research that the brains located in the department of ministry could hold all the information in your mind, and using this along with the creation of the time machine that the Unspeakables in the department of time created they could send a person's brain back in time to a specific point with a very high accuracy.

The process however was long and hard. To achieve this, they had to get a brain before it could absorb the aggressiveness and brutality of the other brains. The smaller brain, like a baby, would absorb information like a sponge, and the information that was absorbed happened to be the first thing that it could stick its tendrils too. It took four brains in total to transfer everything from Harry's mind that he needed for the trip.

"Are you ready Potter?" a man named Gordon Brown asked him. He was sitting in a slightly arched chair that was connected to four brains. On his right was a dial that was set to the day before he turned eleven. If everything went according to plan, he would wake up under the cupboard at the Dursley's with all of his memories intact.

"As ready as I'll ever be, sir" Harry replied eagerly. Gordon flipped began preforming the ritual, pouring magic into the brains. Soon, Harry fell asleep but Gordon kept going. He began to chant, and dance around Harry's a sleep body before something went terribly wrong. The machine that they were using began to overfill itself with magic, which caused one of the brains to disconnect but Gordon could not stop. They had tested this on hundreds of rats, and every time they didn't complete the ritual the rat died, so he kept going.

Finally when he was done, the sensor went off to tell him that he had completed his task and Harry's mind had been sent back. Twelve lab aids rushed into the room at once and began to magically collect the brains for further test and to analyze what went wrong.

"What in the hell happened I want a full report!"

"It seems as if the runes we used were too powerful. It caused this brain to detach. Fortunately it was only most recent memories. I'm afraid when Harry wakes up, he will have forgotten the last ten years of his life."

A/N: So what do you guys think? You know what I think? I think that you should review!
