Some Secrets Are Meant To Be Kept- or otherwise known as Leila Potter, the Twin Who Lived

Summary: AU. Leila Potter is just an ordinary girl. Okay, that's a lie. Leila Potter isn't an ordinary girl. She's the twin sister of the BWL, a best friend and a girl friend of a Black (formally Malfoy), and the entire country of Britain thinks she's a liar. She's been fighting for her life since she was nine, and ended up getting chosen by Hogwarts. But when seven books about her life arrive from the future, things really start getting messed up. The dead come back to life, the future travels to past, and worst of all, her secrets are revealed to the world. Beware Hogwarts, because some secrets are meant to be kept...

AN: This is an AU story, which means that it will vary from Canon. In this fanfiction, Harry Potter has a twin sister named Leila Potter, who is ten minutes older than Harry. Nymphadora Tonks also has a younger sister named Reyna Tonks, who is currently in fifth year. Terry Boot will be a muggleborn. There will also be other Original Characters that I have created. The explanations about them will come up in later chapters. I realize that a lot of things that happen in this story definitely did not happen in Canon, and I am not trying to say that it did. If there is anything that you do not recognize from Canon, they are all a figment of my imagination. This is a 'reading the books' fanfiction, a 'Harry has a twin sister' fanfiction, and the 'wrong Boy Who Lived' fanfiction all rolled into one. I hope you enjoy.

Note: This chapter has gone through editing, and now (hopefully) contains less grammatical errors, plot holes and various other mistakes. (Dated: November 9, 2014)

Leila Potter slammed her head down against the table inside the Great Hall during breakfast one Monday morning. In one hand, she was holding yet another Daily Prophet newspaper with slanders against her all across the front page, this time titled, "The Sister of the Boy Who Lived- an attention seeking liar". However, that wasn't the worst part. Leila kept staring at the name Percy Weasley mentioned in the article- apparently he had given a statement saying Leila had lied constantly, caused chaos and manipulated everyone and even has been sleeping around during his time at Hogwarts- even attempting to sleep with him a few times. That was a lie of course, but it didn't stop from hurting so much.

"Are you okay, Leila?" Neville's voice asked. She had bitten down on her lips too hard, it seemed. She could taste the blood in her mouth.

"Do you want to go see Madame Pomfrey?" Neville sounded worried.

"No, Neville." She said. "I'll be fine. I'm just tired, that's all." Her voice sounded fake, even to her ears.

Leila couldn't help it. She had been having a horrible headache curtsey of Voldemort for weeks now. No potions or muggle medication would help with the pain and the best she could do was just grit her teeth and suck it up. She'd had another detention with the Toad last night, her hand was still stinging, the scars were only covered beneath layers of muggle concealer, and glamours.

Umbridge had threatened to use the cruciatus curse on her in her next detention, waving away her claim that it was illegal by saying nothing that Fudge doesn't know won't hurt him. She had also threatened consequences in case she told anyone, as no one had any power over her currently. Sadly, Leila knew every single of her threats were true. Umbridge didn't look it but she was dangerous and no matter what, she had a lot of influence and power on her side that could destroy anyone she wanted to.

Leila could feel Draco's concerned gaze on her and she nodded to him as if to say that she was okay. She knew Draco wouldn't believe it but he would leave it alone for now. Just as she took a piece of toast and began to nibble on it, the High Inquisitor entered the hall in all her pink, gag-inducing glory. She stood up, and cleared her throat, making many students and teachers look at her in disgust.

"Hem, hem. Students and teachers, if I could please have your attention please?" Merlin and Morganna, what did the toady want now? Slowly and grudgingly, the students began to turn their attention to the pink toad.

"Good morning, Hogwarts!" she exclaimed brightly.

Silence. Umbridge frowned.

"I would like you to say to me; good morning, Professor Umbridge, please. Let's try this again, good morning, Hogwarts!" she said patronizingly, like she was speaking to a group of five year olds.

"Good morning, professor Umbridge." The students murmured back half-heartedly. Umbridge grinned, and Leila turned herself away momentarily from the sickening sight. She caught sight of Reyna, making gagging faces at her from the Hufflepuff table. Leila smiled, feeling a bit better and turned back towards the front as Umbridge began to speak again.

"I have an interesting announcement to make to you, students. Last night, I was in my office after a detention with one of the students." Leila scowled. She was talking about her. "And I received a very... special delivery."

"A love letter from Filch?" Fred muttered. The Gryffindors around him held back a smile.

"The delivery, was a series of books... from the future." There was a few gasps at that, but most students looked like they didn't believe her. Leila though, began to get a bad feeling in her gut.

"The books, seven in total, is about one of the students here and yes, I am talking about you Miss Potter. There was a letter that was delivered along with the letter and it said that it will reveal the truth about all the lies that you have been telling this year. The books are written in Miss Potter's point of view, detailing every year of Hogwarts that Miss Potter has been studying. And I, after much consideration, have decided to read this out to the whole school and invite a few special guests along with us." Some students gasps, others sceptical and some, particularly Parkinson and Smith, gleeful.

Terry stood up. "You can't do that, can she professors? This is an invasion of privacy." He protested, others nodding, especially the members of the Army of Hogwarts, and few of the Gryffindors and Slytherins.

"I am afraid not, Mister Boot. If the facts are true, which can be checked by a truth charm, there is no law prohibiting this. Unless Miss Potter is afraid to reveal the truth about the lies she has been telling, it is perfectly legal. I have checked them several times with all the truth charms I know and all the professors are free to check them as well." Umbridge sounded absolutely delighted.

And meanwhile, Leila was cornered. If she accepted, every single secret she has had, every single rule-breaking and pranks she had done, even all the laws she broke would be revealed. Everyone would know about her past; her life at the Dursleys, Patrick. All of her secrets, private moments, weaknesses.

However, it would prove to everyone that Voldemort was indeed back and reveal Sirius's innocence and Hagrid's unjust expulsion, amongst many other things. She glanced at her twin and saw him looking at her straight in the eye, for once in a very long time. She saw pleading in his face, as well as hope. She knew why Harry wanted her to do this. If she agreed, the whole school would know of Sirius's innocence and he would be able to live with his godfather. And no matter how much she didn't want to, she had never been able to refuse her twin anything, even if he still hated her.

She needed to check for the proofs though, so she stood up and asked.

"I agree to read, but I need answers to some questions first. Who sent them? You said a letter arrived with the books. Could you let Professor McGonagall read it out to the hall?"

Umbridge scowled at her, but nonetheless took out a crispy folded piece of parchment and handed it to Professor McGonagall, who was seated next to her. McGonagall began to read.

"To Professor Dolores Umbridge

Senior Undersecretary to the Minister of Magic.

Professor of Defence Against Dark Arts

High Inquisitor

Year of 1996

Hello

My name is G.P.B, and I am from the year 2018.

I have sent you a package, containing this letter and seven books titled Leila Potter, the Twin Who Lived.

The books contain details of Potter's years in Hogwarts, all seven of them. They are complete truths, and they were made by a team of Unspeakables.

Two of the books will show the future and the books will reveal the truth of the stories about Voldemort, amongst others.

The books will prove they are true if you use a truth charm on them.

Please read the books out loud in the great hall with all the students, teachers and the guests whose names are provided in the list below assembled.

You must take turns reading the books, and you must read all of them.

No punishments will be given from what the books reveal until the very end.

Please hold any judgements until all seven books are finished.

Thank You,

G.P.B, A.R.B, A.L.B

There will be few more special guests arriving shortly once everyone on the list is present.

Umbridge then performed a few different truth charms on them verifying their truth, then motioned for all the teachers to do the same. One by one, McGonagall, Flitwick, Sprout, Snape and all other teachers performed complex truth charms, every single one turning up positive. Umbridge sent her a smug look as if to say, see?

Umbridge spoke again. "The classes are cancelled for now. You may go get changed into more comfortable clothes and we will assemble back here at nine o' clock, sharp. You have one hour. We will, then begin the reading."

One hour later, everyone was seated at the Great Hall with the exception of two people; Leila Potter, whom this book was actually about and Draco Black (Formally Malfoy), her best friend and boyfriend. The two in question were currently standing outside the doors to the Great Hall, the red headed witch taking deep breaths, trying to calm herself down and the blonde haired wizard waiting for her patiently.

Leila had changed out of her Hogwarts robes and was now wearing her regular outfit- dark comfortable pants, a t-shirt, her leather jacket and her silver belt, with her knife sheathed as usual. Her curly hair was down, hanging to her waist like it usually was outside of class. At her feet was Kairo, her wolf-dog, who usually accompanied her everywhere out of class.

Draco was also wearing muggle jeans and a grey sweater, and in her opinion, looking very good as usual though she'd never ever tell him that. He had his arm around her shoulders, silently lending her strength and giving her something to focus on other than the panic she had initially felt.

Leila smiled at him slightly, then looked back at the doors and squared her shoulders. Straightening her spine, she controlled her facial expressions, adjusting it back to the cold, stoic look most people saw when they looked at the red-haired Queen of Hogwarts. Clenching her teeth, she took a final breath and ignoring her instinct that warned her that this was a horrible idea, she shook off Draco's arm, quickly squeezing his hand then reached forward, opening the doors and stepped inside.

The Great Hall had gone through a major transformation. Instead of the four house tables, someone (most likely McGonagall, the Transfiguration professor) had pushed away the long tables and instead in its place, conjured many small-to-medium sized tables around the big room with soft and comfortable looking armchairs around them. The only thing that remained unchanged was the long staff table at the front of the room, with all the professors already seated before it.

None of the occupants of the Hall looked too happy about their delay but if they were going to read a book about her private thoughts, Leila figured they could afford to wait a little anyway. Keeping her face blank, she, accompanied by Draco and her dog, walked to the medium sized table that could hold around eight people at the very back of the room. Terry and Reyna were already seated, holding the table for them. They sat, Leila facing Reyna and Draco on her left facing Terry. Kairo curled around her feet, as they waited for someone to speak.

"Well then," began Umbridge, her annoyingly sugary voice dripping like poison, "now that Ms Potter decided to grace us with her presence, we will now be able to begin revealing the truth soon. The guests are arriving now as we speak and this situation has already been explained to them. I have also been informed-" and here she was cut off by the doors opening yet again.

In walked all the guests specified in the letter. Cornelius Fudge and Amelia Bones led the crowd, Fudge looking pompous with Amelia looking stern. Behind them followed Percy Weasley, not even glancing at Leila and Leila breathing in sharply as the person who she had looked up to as an older brother walked by ignoring her. Of course, he had also spread all her secrets and many lies about her to the press and had called her names to her face a few months ago. Some older brother he was, let alone a friend.

Behind them, followed the Order of Phoenix, Dumbledore leading them and many students let out a cheer at seeing their old headmaster back again although Leila was not one of them. The vibrant, orange-red hair of Weasleys also passed, Bill and Charlie sending a friendly smile at her and Reyna, which she responded with a nod. Mr. Weasley waved his hand at her and Terry.

Nymphadora walked in with them, with her hair pink as usual. She stopped by their table to give her sister a quick hug, winked at Leila and Draco before moving on. Er... attempting to walk on, before she tripped and almost face planted. Terry quickly caught his girlfriend's sister as she thanked him with a slight grin, embarrassed.

Lupin and Sirius Black also entered the hall, causing the students to scream at the sight of the infamous Azkaban prisoner until Dumbledore spoke up and promised them that they were not in danger. After all, if Dumbledore said it was safe, who were they to question? (Note the sarcasm.)

Fleur Delacour and Viktor Krum also walked in, both sending a warm smile to their formal fellow tri-wizard competitor. Gabrielle, bouncing next to her sister, gave her and Draco a quick hug, before moving on and sitting down next to Fleur and her sister's boyfriend, Bill.

Umbridge was scowling at how long that had taken.

"Hem, Hem. As I was saying, I had been informed by Mr. G.P.B that there will be a few more special guests arriving after the first chapter. So if we may now begin?" The pink toad demanded. Umbridge picked up the first book and floated it to Leila, who was glaring at her.

"The first book is called Leila Potter and the Philosopher's stone. If Miss Potter would like to begin?"

"I'd rather not, ma'am." Leila answered.

"Well, Miss Potter, it appears you have no choice. Unless you'd like to get another detention, you may now begin." Leila imagined burning a hole into her forehead but when Umbitch raised her eyebrows at her, she had no choice but to begin, her left hand still stinging from last night.

Leila sighed. "Chapter One, the Twins Who Lived."

AN: I wasn't planning to start this before I updated the Power He Never Knew, but as I seemed to be stuck in a writer's block for my other story, I decided to start a new fanfiction. As I mentioned earlier, this fanfiction will be a combination of several of HP fanfiction clichés, but with a twist (or several) to them.

I know there are several of these kinds of stories, but please give this one a try. If you have any questions, please leave them in a review, and I'll try to answer the ones I can in ANs, or within the story.

As I will be writing this with the Power He Never Knew, the updates will be slow, so please just keep watching! I will get back to the PHNK as soon as I get out of this little pesky writer's block. I'm sorry for those of you who are waiting for it.

Just in case any of you were wondering, the main character Leila in this fanfiction is in no way modelled after me, even though she shares the same name as my pseudonym.

I hope all of you had a Merry Christmas (or any other holidays you might celebrate), and Happy New Year!

Love,

Leila xo
