A/N: Okay to start with this story will contain a trans Harry, as you saw from the summary. If your not comfortable with that this won't be the story for you. Now this story wasn't just done by me it was done with a very close friend of mine. We where up late together one night and started writing it. As you know if you read any other of my work I'm not the best with grammar, so I apologies in advance for that. Nor is my friend or I'd have got them to beta it when we where working on it. But if you'd like to beta this please message me. Now after saying all that I hope you enjoy :) All rights to respectful owners.

Harry Greengrass Potter. Adopted child of the Greengrass family was in line, with his adoptive sister Daphne Greengrass waiting to be sorted.

But I think we're getting ahead of our selfs. Harry Potter was not the boy who lived. Harry is the son of James Potter and Rosie Potter nee Greengrass. Harry's parents where not supports of the Dark Lord, but nor did they support Dumbledores cause either. Rosie being a Greengrass by birth always knew to play the neutral role in times of war. But let's say that always kept you safe from the Dark Lord if you where of the right sort and did not oppose the Dark Lord you where safe. But that did not make you safe from certain Dumbledore supporters. They had the view of you where either with the Dark Lord or against him, and Harry's parents had been killed in an attack. Harry luckily was whisked to safety by his Mother through an illegal portkey. Thus Harry was taken in by his kind uncle and his equally kind mother.

The Dark Lord had attacked Frank Longbottom and his wife Lilly Longbottom. But he failed to kill their son Neville, and the killing curse meant for the small boy had rebounded.

Harry grew up with his cousin and best friend Daphne. She was great and Her and Harry were inseparable. Harry had never really had any make friends. He was good friends with two other girls tho. Pansy Parkinson and Tracy Davies. Noted they had never treated Harry any different and Harry was always the most comfortable around them. Harry didn't like to admit to to much but when the girls gave each other make overs, and always got Harry to join in he sort of liked it. He never really liked his hair cut either. It took him a while but him with Daphne's help manged to get his blonde her tamed. He may have the traditional Greengrass blonde hair and blue eyes, but he had his fathers untameable now tamed wild hair. Noted it took him allot of work every few days tho. He didn't look,like the average boy either. He was rather slim but not underweight as he was never starved, nor treated with neglect. His aunt and uncle treated him just the same as they, treated Daphne and his younger cousin Astoria. She also occasionally joined in playing with Harry and the girls. All in all Harry had a good childhood.

Harry had just watched a girl by the name of Millicent Bulstrode get sorted into Hufflepuff.

Harry wasn't paying much attention to the sorting, well that was tell one of his best friends was bellow the hat. It took a while but the Hat declared her a Slytherin.

Very soon after this the stern witch was saying the name. "Greengrass Daphne."

The hat also soon declared her a Slytherin.

Then the witch called out. "Greengrass Harry."

Harry heard things like. "Aww she's cute and so small." Or "Why does such a cute girl have a boys name."

Harry had a mask on tho, it was common with the agree grasses not to show emotion in public.

The words people where saying Harry paid it no heed. In all honesty he did not know how he felt about him self. But one thing was sure he'd know when he knew.

"Hello" Harry thought.

"Hello to you too." The hat Whispered back.

"Now where to put you. Your mother was a Slytherin. But your father he was a Ravenclaw."

"Wherever you think is best." Harry thought.

The hat chuckled in his ear. "Much more logical than your father. He begged me to put him in Gryffindor like your grandfather on his side. But alas he favoured Ravenclaw and he did great. Like him you don't belong in Gryffindor and I can see you don't want to go there any way. Your loyal, intelligent and recourseful. Your sister is very close with you I see it in both your heads. You may need her with what's to come. But I can't put you there just for that, but it's clear you belong their either way. So like your mother you belonging in SLYTHERIN!" The hat yelled the last words.

The Slytherin table burst into applause.

Harry got up and neatly placed the Hat back on the stall.

Harry soon found him self sitting next to Daphne.

"People being telling me how cute my little sister is." Daphne whispered in Harry's ear.

Harry's mask slipping. "Y-yo-you corrected them right!" Harry exclaimed quietly.

Daphne giggled. "What's the point it's not far off."

"I'm a boy Daphne." Harry said in a wary voice.

"Physically maybe."

"Yes physically!" Harry snapped.

Luckily no one overheard their conversation.

"Will talk more tonight in the common room, okay sis?" Daphne teased.

Harry nodded but did not say a word. Daphne just giggled at the indignant look on Harry's face.

Their other friend Pansy also joined them in Slytherin.

That night in their common room, their head of house Severus Snape gave them a spach. It was about how Slytherin puts up a united front out side the common room, and that any issues are to be resolved within theses walls.

Harry had made to go up to the Slytherin boys dorms, when the fifth year male prefect stopped him.

"Think you got the wrong door young lady." The boy Marcus Flint smiled at him.

Harry was about to say something when Daphne came over. "Oh sorry about her she's very tired." Before Harry could protest, Daphne had led him away.

"Daphne what do you think you are doing!" Harry hissed at his sister.

"Oh ain't it obvious we room in twos. Pansy has agreed to share with Tracy. Meaning you and I can share a room. The magic of the dorms will create an extra bed and have your trunk their."

"One issue."

"What's that Harry?"

"I'm not a girl!" Harry whispered harshly.

"Physically." Daphne said as she led Harry down the girls corridor."

"Whatever." Harry said as they arrived at a door that said Greengrass and Greengrass first year. They entered the room and as soon as they did Daphne locked the door, and put up a silencing charm.

"There now you can yell tell your harts content. But before you do up you read Hogwarts and History too. Well we where both forced to. Only girls can go down the girls dormitory entrances." Daphne said calmly.

Harry opened his mouth and closed it again. But then he finally spoke. "What does this mean?"

"Well Harry it means Hogwarts recognises you as a girl."

Harry gaped in shock.

Daphne gestured towards to arm chairs by a window that looked out onto into the lake.

"Harry look you know as well as I do, it's not even cared about if a person feels they are physically the wrong gender. In fact it happens a lot. But it tends to happen before the young person goes to Hogwarts. Mummy and Daddy would not care and you know they won't. Give it a think over the year you might feel you are a girl. You enjoyed doing all the girly activities with us growing up right?"

Harry nodded.

"We didn't force you to did we you joined in because you wanted to?"

Again Harry nodded.

"Oh and you still can claim what your parents left you when your of age, so,that's nothing to fear their is it?"

Again Harry nodded.

"So will you give it a think over the year, and spend it with your big sis in our dorm room?"

"Sure sis il give it a think and a try." Harry said quietly.

"That's all I ask for."

Harry then spoke. "But to be on the safe side. I call on the power of Lady Hogwarts, I Harry James Greengrass Potter declare to Hogwarts, my name is now Harriet Jessica Greengrass Potter tell I declare otherwise."

Daphne looked confused. "What was that about?"

"You read Hogwarts a history but I shall explain, it's a big and boring box after all. For students who feel born in the wrong body. Or for children from troubled backgrounds or disowned. They can call on Hogwarts to recognise them as a name they see fit, the book of admittance will then read their new chosen name and all the registers and records will, change to show that. I chose Harry as people will just think, McGongal may have shortened my name to get through the sorting quicker. Teacher know not to question students who have changed their names, as it's illegal to ask them. Well unless the teacher a close family friend or family. Also it seems less likely to cause an issue me sharing a dorm room with you then."

"Very Slytherin of you sis." Daphne said.

For some reason He was fine with her calling him that. He still wasn't fully sure if he was a boy or a girl. But Daphne calling sis was fine with him.

"Thanks Daph."

"Oh I got something. You don't have to take it but let's say you end up in the hospital wing, it may be prudent you take it. Another good cover in case people get suspicious about us sharing a room." She had gone over a trunk and pulled out a box. It was full of vials full of a purple potion.

"What does it do?" Harriet asked questioningly.

"Let's just say it rearranges down there." She pointed to Harriet's private area.

"Does it hurt?" Harry questioned.

"Don't know to be honest. I got them for you behind mummy and daddy's back, just in case anything like this did happen this year." Daphne said.

Harriet did not know what to say. It was strange Daphne had been so forward thinking. But did she know Harry never truly felt right as a boy but no clue what them feelings meant.

"How long does it last?" Harriet questioned.

"Three days there a terms supply in there." I think if you take one before it runs out, it is like the pollyjuice potion it extends it and doesn't make the transformation have to happen again."

Harriet didn't think it could hurt trying it. Daphne wouldn't ever do anything to hurt him. He uncorked a vial but handing Daphne the rest of them first. then he downed it in one. It was painfully thank magic Daphne had put up silencing charms. Harry screamed a lot. Daphne putting the box down, quickly ran over to her cousin and embraced them.

"Shh shh." She comforted Harriet. "It's alright I'm so sorry I didn't know how painful it would be."

"It's fine." Harriet rasped out.

Daphne smiled at her cousin. "Did it work?" She questioned.

Harry checking in his trousers under his robes nodded. "Think so."mother both laughed. Daphne's eventually spoke again.

"Good well as long as you re take the potion regularly it should not hurt next time."

Harry nodded.

"Oh yeah and I don't think girls are allowed to wear trousers, but don't worry I got plenty of spare skirts I can lend you, and a spare pair of girls school shoes."

The small figure in Daphne's arms burned with embaresment.

"Oh what's the difference doing it with me and the girls when we played dress up, with dresses and skirts."

"What if someone works out I'm physically a boy. Even though I'm not so sure what I am. To be honest I haven't for a while."

"Well we correct them." Daphne said in a matter of fact tone.

"We?"

"Yes we sis. Boy or girl il love you either way."

"Thanks Daph."

"No problem Har."

Harriet giggled.

Now they had dealt with the issue at hand the looks around their room. It was comfortable. To queen sized beds with green velvet hangings and Canope. A walking wardrobe. A book shelf and a large work desk that could seat two. Their was also a roaring fire. Where they had sat before as well as the two arm chairs their was also a table with a chess set on it. There where a few cupboards for storage. By the fire there was also a sofa that could seat two made of emerald leather. With two arm chairs at either end made of the same leather. Their bathroom had two toilets and sinks. As well as a large area to get ready in the mornings. Their where two showers with many different features. Plus a small sunken pool that was a bath with many different taps and features as well. It wasn't colossal but it was clear you could relax in it and maybe even swim. Their was also a window that looked out into the lake as well.

The pair deciding they'd unpack in the morning. Daphne had cancelled the silencing charm and the pair got ready for bed.

The bed was so soft and plush with many different pillows and cushions. Harriet was asleep as soon as her head hit the pillow.

A/N: So I am guessing if your here you made it all the way through. I hope you enjoyed it and you'd read more of this. I have no clue who I'm going to pair Harriet with yet but am open to suggestions. One last thing Harriet doesn't wear glasses. Her eye sight was corrected when she was younger.
