Author's Note: I wrote this in for SaphirePhoenix's challenge, The Sex-Change.

RULES:
-Harry Potter must be born a girl, but no one knows except her parents, obviously the Dursleys, Dumbledore, and any select person you may choose.
-Harry (pick any girl name you want, preferably something that could be mistaken for 'Harry')
-She must pretend to be a boy for a select period of time. You choose why, although I doubt anyone can understand Dumbledore's crazy schemes.
-She can be in any of the four houses,I'm partial to Gryffindor or Slytherin.
-She must gradually become friends with Draco Malfoy; it could evolve into a relationship from there if you want.
-People WILL find out the truth eventually. Let a few learn her secret at first, then the whole wizarding world can find out.
-And finally, NO HET or SLASH. Implying that someone has a crush on 'Harry' Potter is okay, as long as the real (female) Potter isn't attracted to any other girls.

Summary: Harry Potter was born as a girl named Hayden Potter. She defeated the Dark Lord Voldemort, only to be reminded as the Boy-Who-Lived, Harry Potter not the Girl-Who-Lived, Hayden Potter. She was then sent to the Dursleys', where she's uncared for, unloved and unwanted. (Mentions child absue. Has Manipulative Dumbledore, Dumbledore Bashing, Weasley Bashing.)

Disclaimer: I don't own Harry Potter, J.K. Rowling does, along with a bush of other people. This is not being sold or making money of any kind. I'm only writing this fanfic for fun.

Kept Secrets, Hidden Truths, New Worlds
Prologue: You're Beautiful

You're beautiful. You're beautiful.
You're beautiful, it's true,
I saw your face in a crowded place,
And I don't know what to do,
Cause I'll never be with you.
-James Blunt from Back to Bedlam

James Potter, Sirius Black, and Remus Lupin all crowded around the hospital bed of Lily Potter looking at the bundle in her arms. In her arms laid a baby girl, no more than a few hours old, in a pink blanket. James sat up by Lily with his arms rapped around her waist. Sirius stood next to him with Remus opposite James.

"Prongie," said Sirius after a few minutes, "I thought you said it was a boy, not a girl."

"That's what the Healer said," replied James

"What are going to name her?" asked Remus.

"While we were going to name him Harold James Potter, Harry for short," said James. "How we're back to square one."

"How about Rose?" asked Sirius.

"One of my aunts was named Rose, I didn't really like her," said Lily. "I really don't want her first name to be a flower either, maybe her middle name."

"How 'bout Yuri?" asked Remus. "It's Japanese for 'lily'."

"It excellent, Remus," said James. "Yuri Jamie Potter! Yuri after Lily and Jamie after me! Now we just need a first name."

"Something close to Harry," said Lily.

"Happy?" asked Sirius.

"No, Padfoot," said James, "or Harriet."

"Hayden," said Lily after a few minutes. "Hayden Yuri Jamie Potter."

"Sounds good, love," said James.

For there Sirius was named Hayden's Godfather and Remus the second Godfather incase anything should happen to Sirius. After Hayden was born, Albus Dumbledore told Lily and James about a prophecy linking Hayden a defeater of Voldmeort, even though she was 'she' not a 'he'. He made them go into hiding, even though James had a safer place than someplace with a Secret Keeper.

So the Potter family went into hiding with Sirius as their Secret Keeper, but later switched to Peter Pettigrew, another family friend, since everyone thought Sirius would be the Secret Keeper and people thought Remus was a spy from Voldemort. But on Halloween, Lord Voldemort came to their house and killed Lily and James Potter. He then tried to kill Hayden, but when the evil wizard shot the deadly curse, it backfired on him.

Sirius then went after Peter, to confront him for what he did to Lily and James. He found Peter in a muggle street, but Peter told everyone Sirius betrayed Lily and James to Voldemort. Peter then cut of his own finger, shot a curse, which killed twelve muggles, and transformed into a rat and fled.

Hayden was later picked up by Rubeus Hagrid and brought to Number Four Private Drive to live with her last remaining relatives, the Dursleys'. Which were her Aunt Petunia, Lily's older sister, her Uncle Vernon, Petuntia's husband and her cousin Dudley, their son. There Hayden Potter grew up not knowing who she truly was, while the wizarding world praised Harry Potter the Boy-Who-Lived, it was all according to what Albus Dumbledore told them.

Hayden: It can be a boy or girl name and it's close to Harry.
Yuri: It's the Japanese form of lily
Jamie: More of a feminine version of James
