Disclaimer: Unfortunately for me, and fortunately for everybody else, I am not J.K. Rowling and I do not own the Harry Potter series.

AN: This story is canon up to the fourth book. Just a random idea I had. Review to tell me if I should continue. This chapter is really short because it's the prologue, the next chapters will be longer.

"This is no use," Hermione said, snapping shut Weird Wizarding Dilemmas. "Who on earth wants to make their nose hair grow into ringlets?"

"I wouldn't mind," said Fred Weasley's voice. "Be a talking point, wouldn't it?"

Harry, Ron, and Hermione looked up. Fred and George had just emerged from behind some bookshelves.

"What're you two doing here?" Ron asked.

"Looking for you," said George. "McGonagall wants you, Ron. And Dumbledore sent a message for Harry."

"Why?" said Harry, surprised.

"Dunno," said Fred, shrugging.

"Well…" said Ron, "wouldn't want to keep McGonagall waiting." He slouched off. Fred and George followed him out.

"Aren't you going to open the note, Harry?" asked Hermione.

"Wha- oh, yeah." He unfurled the tightly rolled paper.

Harry,

Would you and Ms. Granger be so kind as to join me at my office at your earliest convenience?

Albus Dumbledore

P.S. I like Chocolate Frogs.

Wordlessly, Harry showed the note to Hermione, who immediately jumped up. Harry followed her out of the library. As soon as they were out of the library and Mrs. Pince could no longer swoop down on them, Harry began to talk. "Why does he want to see both of us??"

"I don't know…if he doesn't want to see Ron too, then there's nothing that we've done…maybe he figured out I helped you on the first task. I'm still trying to figure out the postsript. Why chocolate frogs?"

"You just taught me a spell - Accio. Nothing much. I think chocolate frogs is the password." They had reached the huge, ugly stone gargoyle guarding Dumbledore's office.

"Chocolate frogs!" declared Harry, confidently. The gargoyle moved to the side. Hermione stepped onto the staircase and pulled Harry after her. The staircase spiraled upwards. Hermione clutched Harry's hand tightly, in fear. They had reached the door to Dumbledore's office. Hermione raised a hand to knock, but the door swung open before she had the chance.

"Ah, Mr. Potter, Ms. Granger, please have a seat." Dumbledore was sitting at his desk, beaming. Harry shot a look at Hermione, then sat in one of the chairs Dumbledore had indicated.

"Now, you must be wondering why I've called you here." Hermione opened her mouth to answer, but Dumbledore cut her off. "There is something the two of you must know. You may tell anyone you wish about this, but please exercise caution. You see, Hermione, your parents are not who you think they are…you were adopted."

"What?!?"

"It seems shocking, and indeed it must be to you, but we – I – have decided it is time to tell you the truth. Lily and James knew that twins were very powerful, that Voldemort might go after twins, so they gave one up for adoption. It was one of the hardest decisions they ever made…"

"So Hermione is -"

"Yes. Hermione is your twin sister."

"Um, sir, if I may ask something…" Dumbledore nodded. "Why are you telling us this now?"

"Dark forces are stirring, Harry, family is the most important thing we have right now…Harry, the second task is tomorrow, so I suggest you get some rest. And know that none of what has been said here tonight is known to the rest of the world - it is imperative that you keep that in mind. I'm truly sorry for the deception, and my abruptness. Ms. Granger?"

Hermione, who had been looking down at her feet to hide the tears that were pouring down her face, looked up.

"I'm sorry. I believe Professor McGonagall would like to see you." Hermione nodded. "Good luck, Mr. Potter." And with that, they were dismissed.

As they went down Harry opened his mouth to speak, then closed it again. How could you say anything when someone had just found out that their whole life was a lie. Instead, he put his arm around Hermione and hugged her. He still couldn't believe that she was his twin sister…
