Disclaimer: Harry Potter isn't mine, but I sure like writing about it!

Author's Note: I have a fondness for Time Travel Fix-It stories, a tried and true trope. Hermione and Luna are my two favorite characters, as well as my OTP, and frustratingly there are not very many fics that include both of these. That said, this story has been influenced by many a time travel fix-it, namely Faery Heroes by Silently Watches (FFN) and Dodging Prison and Stealing Witches by LeadVonE (FFN & AO3). Hermione Granger and the Serpent's Renaissance by epsi10n (FFN) and The Arithmancer/Lady Archimedes by White Squirrel (FFN) were also major influences. As this story goes on, I'll be making fic recommendations every chapter. The summaries for these four will be at the author's note at the end of the first chapter. Thank you to cyborg_goddess for beta reading this. Now on with the show!

Everything was going to plan. After reclaiming Grimmauld place, with the consent of Kreacher this time, they had been able to find a hidden ritual room. Harry, never having taken Arithmancy or ancient runes, wasn't very interested. But Hermione, well, Hermione was interested in everything. And when the war started to pick up again, she started looking in earnest.

It all started with the battle of Hogwarts. Or rather, that's when they started to see it. McGonagall ordered that all the Slytherins be put in the dungeon. Some of them were only eleven years old! Hermione fumed to herself, ten years later and still bitter. Maybe if we hadn't all treated them like scum they wouldn't have done the same to us. Shaking her head, Hermione refocused on her rune work. She had to get it just so, or it would all be for nothing. She won't leave me behind, and I won't leave her. It was the same argument over and over. The ritual called for two travelers and an anchor, and Harry had to go. He was the Chosen one, and they were just loony and the mudblood. Hermione decided to stay behind. Unless I can fix this. I have to fix this. Harry was the one to suggest that they go without him, and so really all of them wanted to be the one to stay behind. And none of the others was having it.

Which is why Hermione had been working in the ritual room for so long. It had been two years since they decided to do this, one year since they found something that would work, and six months since they came to this ridiculous stalemate. And all the while there were 'aurors' outside Grimmauld Place. Oh, Voldemort was definitely dead. And so was Kingsley, and McGonagall, and Andromeda, and Teddy, and anyone with the last name Weasley. The three of them were the last ones left and the only person that would have anything to do with them was oddly enough Draco Malfoy; who was the only reason they still had food. Undesirables 1, 2 and 3 meant that they couldn't leave without risking death. Draco snuck them food, and newspapers, and books, but that was about it unless they wanted to go in the muggle world, and even that wasn't safe anymore, now that they tracked magic. The three of them were at each other's throats half the time, and studying the other half.

"I think we should bring in Draco."

Hermione jumped at the voice she hadn't heard behind her. "Harry! Don't do that, do you even know what could happen by scaring someone in a ritual room?"

Acting as if he hadn't heard her, Harry continued. "I know I'm not as smart as you, Hermione, but I took a look at the rune schema. We can send three people as long as there is a fourth anchor. I think we should bring in Draco. And Luna agrees with me."

Hermione paused, and weighed his words. "It would be awfully risky…"

"So is doing this in the first place. We are talking about rewriting a decade of history. That doesn't come without some risk and the longer we wait the harder this is going to be."

Hermione bit her lip. He did have a point about waiting too long. There was only so far they could go back, especially when accounting for the fact that three people was an even larger strain on the timeline. "Give me a night to think it over, and I want to talk to Luna about this myself."

"Hermione -"

"Whether we've been talking recently isn't the point. She's my wife, and we have to talk to each other at some point." Hermione sighed. "I'm not going to get any more work done tonight, and if I agree to this it will require changing a lot of this any way." Hermione stood up and stretched. She had been hunched over for she didn't know how long.

"Thanks Hermione." She made to pass him and he grabbed her arm. "Please Hermione I -"

"I know Harry. I know."

Hermione didn't need to give it as much thought as she expected. Weighing the pros and cons and possibilities as she looked for Luna, it all stopped in her mind as she finally found her, sleeping on one of the armchairs in the library, book almost falling out of her hand. By God she loved this woman, and knew in an instant that she wasn't letting her go for anything. Leaning over, she gently took the book from Luna's limp hands, placing a nearby bookmark inside before placing it on the table. She tucked a stray strand of blonde hair behind Luna's ear and smiled when she shifted in the armchair and slowly opened her eyes.

"Hi."

"Hi."

"I'm sorry," they both said it at the same time and then giggled.

"Harry asked me if -"

"Yes. It will work I looked it over and the wrackspurts are all gone now."

Hermione's smile widened. The creatures she had once scoffed at now became a source of comfort for her.

"Let's do it."

Things were not as simple as they hoped. Draco was amicable, but not being versed in runes or arithmancy, it took him a while to fully understand the process. Three days before the scheduled time of departure he stumbled into the house at one in the morning, interrupting Harry's sleep and Luna and Hermione's nightly activities. They all rushed down the stairs, anxious and wands ready.

"We have to do it now. They're on to me, they're coming. I don't know how, but they found out."

"We're not ready!" Hermione's mind flew in a hundred different directions before Harry caught her arm and brought her back to reality.

"We have to be."

Hermione Jean Lovegood woke up to the sound of her mother's voice. "-And don't forget to brush your teeth!" For a moment she was still, before she sat up with a start, her heart beating fast. The last thing she remembered was holding on tightly to the hands of Harry and Luna as the house shook around them, and Draco's face of pained horror as someone behind him shouted Avada Kedavra.

Taking deep breaths Hermione observed her surroundings. She was in her bedroom at her parents' house. It was with horror that Hermione realized her walls were pink. She had painted them blue the summer after second year. How young was she? This was not the plan. This was not the plan! In the back of her mind she heard Harry's voice "When have any of our plans actually worked?" Smiling at the memory of her friend her heart sped up again as she thought of her brother and her wife, and whether or not they had made it back. Climbing out of bed, Hermione dug through her desk drawer until she found her diary. The last entry was from June 31st, a Tuesday. She never went more than a day or two without writing in it, so it had to be sometime in the beginning of July, probably Friday or Saturday. It felt almost wrong to read it - she was twenty-eight, not 13.

Dear Diary,

We're leaving for France next week, and I wanted to call Harry, but Ron said that Harry's uncle was really angry when he called. I do hope that he didn't do anything to make him angry. I know Harry said his uncle shouts a lot. I don't want to get Harry into more trouble by calling him, but I would like to talk to him before we leave. Owls will have a harder time getting over the border I expect.

I've been finishing up my muggle work for this term. I've already completed my Hogwarts homework of course, but I was completely behind on my muggle work since they don't really accept petrification as an excused absence from finishing things on time. I believe my parents told them I had a very bad case of pneumonia.

I've convinced mum and dad to drop me off at Diagon Alley tomorrow; I want to explore more in Flourish and Blotts to see if there are any interesting magic books before we leave the country. Mum and dad said they'll give me a little bit of money, but I can't spend it all on books as I have to make sure I get lunch. Honestly, I know I like reading, but I'm not about to forget to eat.

-Hermione

Hermione laughed at her younger self, knowing full well that she had managed to forget to eat many a time while reading a book. That said, she now knew what day it was. And even better, she knew that calling Harry would be a perfectly safe, and indeed the first thing she did upon leaving her room (with the exception of brushing her teeth of course.

Harry woke to the sound of Hedwig barking. Like lightning he was up and petting her gently through the bars of her cage. His first friend, but not the first, nor the last to give their life for his. No more.

The phone rang downstairs.

Luna and her father were sitting on the roof of the rookery. They had watched the sunrise together, but neither bothered to go back inside when it had already been up for so long. She made a slow blink, and suddenly she felt rather more like twenty-seven than twelve.

"Daddy?"

"Yes my moonbeam?"

"Can I go to the alley today? I want to see about meeting some of my friends from school."

"I thought you said they were all infested with wrackspurts?"

"All but two. It took a while, but they managed to shake them off."

"Grab your cloak, we can get breakfast at the Cauldron."

Luna had on a wide smile as they climbed down into the rookery.

What better way to start the day but with a sunrise and sixteen years of memories?

Author's Note 2: I made a few big changes to canon. Among them are that Luna travelled with the Golden Trio on the Horcrux hunt, that Harry never dated Cho or Ginny (my Harry is asexual) and that money will actually make something resembling sense. There are other changes too, but they're smaller and I don't want to spoil anything.

Fic Recomndations:

Faery Heroes by Silently Watches (FFN)

Response to Paladeus's challenge "Champions of Lilith". Harry, Hermione, and Luna get a chance to travel back in time and prevent the hell that England became under Voldemort's rule, and maybe line their pockets while they're at it. Lunar Harmony; plenty of innuendo, dark humor, some bashing included; manipulative!Dumbles; jerk!Snape; bad!Molly, Ron, Ginny

Dodging Prison and Stealing Witches by LeadVonE (FFN & AO3).

Harry Potter has been banged up for ten years in the hellhole brig of Azkaban for a crime he didn't commit, and his traitorous brother, the not-really-boy-who-lived, has royally messed things up. After meeting Fate and Death, Harry is given a second chance to squash Voldemort, dodge a thousand years in prison, and snatch everything his hated brother holds dear. H/Hr/LL/DG/GW.

Hermione Granger and the Serpent's Renaissance by epsi10n (FFN)

They didn't question why Hermione Granger was able to cast every spell in the first class, or why she seemed to know Hogwarts: A History by heart. They never really noticed her resourcefulness, determination or cunning. A Gryffindor meant for Ravenclaw, they called her- and yet...Who would've thought that once upon a time, her name was Salazar? Reincarnation fic
