A/N: Okay, first some notes.

1. This is not really BASED on PLL, it just has the same idea.

2. The person blackmailing them is not going to be a secret.

3. There will be killing, so if you don't like that:

a). Too bad.

b). Why are you reading Harry Potter OR PLL?

Now for the disclaimer. I don't own Harry Potter or Pretty Little Liars. I think you all know who does.

Finally, read and review!

Luna Lovegood and Draco Malfoy cuddled and held hands as they sat in the room of requirement. It was the only place they could, you see, because if the secret of their relationship got out, it would be the end of the Malfoys as they knew them.

The year Draco was born, the Parkinson family had a little baby girl, named Pansy. Mr. and Mrs. Parkinson, like the Malfoys, wanted to ensure that their child's spouse came from noble stock, so a marriage was arranged.

When Draco and Pansy were both twenty-one, they would be wed, and everyone would be happy.

Except Draco.

He didn't love Pansy. She was an okay friend, but, he loved Luna. Yes, you heard him correctly. He loved her.

Draco didn't just fancy her, or like her a lot, he was in love with the girl most people considered crazy.

But it hurt, to have act mean to Luna, in front of his friends. Draco pulled her closer to him, and kissed the top of her head.

"Love, I have to go to Quidditch practice. Do you want to come back after dinner?" Draco asked, standing up.

Luna nodded. "I'd like that Draco. Have fun at practice."

As they got up to leave, Luna heard a tap at the window. Outside, sat a tawny owl, striking the window repeatedly with its beak.

Luna opened the pane to let the bird in, and took the letter attached. Luna did not recognize the penmanship.

Wouldn't it be terrible if Pansy found out who her fiancé is dating? No where in the song does it say we snakes can keep secrets...

-A

Luna looked around the room, half-expecting to find someone in a hidden alcove. When she didn't, Luna bit her lip nervously, tightly gripping the butterbeer cork necklace clasped around her neck.

Draco had already left, so he probably didn't see the owl. Luna released it out of the window, and watched it fly away.

Then she began to assess the situation at hand. Someone was blackmailing her; someone who knew about her and Draco dating. Luna reread the letter and smiled.

She knew it was a Slytherin, because it said 'we snakes.' That was another clue. Luna stuffed the letter deep into her pocket, then started down to the dungeons.

She had some detective work to do.

Hermione Granger loved the library. It was her home away from home, and it was necessary that she spent as much time in the library as possible.

She didn't want a repeat of her first year. It was the year before she met Ron and Harry, before the business with the sorcerer's stone, they year 1990.

It was the year Hermione Puckle attended Hogwarts School of Witchcraft and Wizardry, and she didn't care.

Hermione Puckle was careless, and only studied if someone forced her. The trolls piles up , and the dreadfuls added up as well. And then, Hermione Puckle got the letter.

The letter that said she had failed her first year, and could repeat it if she desired. But Hermione Puckle was embarrassed. What would her friends say?

So Professor Dumbledore gave her another option, which Hermione Puckle quickly accepted.

'Hermione Puckle' moved to Bulgaria, and Hermione Granger attended Hogwarts in her place, entering first year.

Although no one knew about her secret failure, Hermione's greatest fear was that she would fail again, and be humiliated.

So, she studied as hard as she could, in hopes that Hermione Puckle would forever be in her past.

The secret was buried, and Hermione had buried herself in the library, studying. She saw other students, and didn't think anything of it when she saw a piece of paper on the floor. At least not until she saw her name.

Kind of.

The note was addressed to Hermione P, and she knew what the P stood for. Cautiously, the Gryffindor read the letter.

How's seventh year going? Wait, you're only in six year. Does everyone know why? How would it seem if 'the smartest witch of her generation' wasn't so smart after all?

-A

Hermione swallowed harshly, and glanced around the library. Who sent her this letter? A Slytherin girl she didn't recognize winked at Hermione, stood up and left the library. Was the wink her way of saying it was her? Hermione wondered.

Sighing, Hermione stuffed the note in her bag, and left the library.

She had a lot of thinking to do.

Ginny Weasley was upset. She clenched a piece of parchment in her hand angrily, as she yelled at the fourth year girl in front of her. The Weasley girl's bright red hair was rivaled by her face, red from anger.

"I'm going to ask you again, Astoria. How did you come across my birth certificate?" Ginny cried.

Astoria Greengrass smiled wickedly at her schoolmate.

"I have my ways, Weasley. What, are you afraid of what will happen if someone finds out that you're nothing but a filthy mudblood?" she asked sweetly.

Ginny reached out and slapped the Slytherin. "Tell me! Or I'll enlarge your bogies and make them fly around your head!"

"I don't think you're in any position to be threatening me, Ginevra Weasley. Or whatever your real last name is. You know, the one your muggle parents gave you!"

Ginny swallowed, but she couldn't get rid of the lump in her throat.

When her parents (Molly and Arthur) had first gotten married, they had wanted a baby girl very badly, so they tried. And Bill was born. They tried again. Charlie. They kept trying, and Percy, Fred, George, and Ron were born. Still no baby girl.

Molly and Arthur decided to adopt a muggle girl, ready to pretend Ginevra was a squib. They were overjoyed when she showed signs of magical powers.

But that didn't stop the fact that Ginny was a muggleborn. The Weasleys were not pro-pureblood, but it might cause problems if people knew the youngest Weasley's blood status.

So Ginny silently lowered the hand that, just moments before, had been prepared to once again, slap Astoria.

The fourth year Slytherin smiled evilly at Ginny, who shuddered.

"There's a good mud blood. Now, here's what I want you to do."
