Chapter 1 – Mary Augusta Potter
He hated many things in his world. One of them were children, especially teenage girls who just reached puberty. Their giggles gave him headaches. He shuddered at the memory of his classmates. Making sure that his sleeves were down, he went into the night.
Mary always knew that she was pretty. People kept telling her that she was special and it only gave her more confidence. She wasn't afraid of many things and she loved evening walks. She heard that it helped her complexion stay unblemished.
She reached the road leading to her house, tired after long day. The lights were off on the street. Strange.
She hadn't much time to think as a man emerged from shadows, moonlight illuminated his face, twisted into ugly sneer.
She hadn't time to scream as he grabbed her roughly and shoved behind the corner. Then her world turned black and she knew no more.
Harry, Ron and Hermione were discussing Durmstrang. Well, more like Hermione explained everything she knew to them, as the door of their compartment slid open. There was a girl standing there and the boys' jaw's dropped slightly.
They weren't sure if it was because her jet black hair, or full, pink lips or big, brown eyes. For Hermione it looked like the girl liked the reaction she caused and she spoke after a moment.
"I was hoping to find you," she said in sweet voice, smiling at them. Well, mostly smiling at Harry, but did it matter?
"Oh, um…why?" asked Harry.
"May I come in?"
"Of course," blurted out Ron, causing Hermione to roll her eyes. She didn't like the look he send to that big-breasted girl.
"I'm Mary Augusta Potter," she said, again waiting for reaction to Hermione's irritation.
"Potter?" asked boys simultaneously.
"I- yes, Potter. Are you Harry?"
Harry cleared his throat. "Yes, I am Harry Potter."
"Can you tell me what's this strange coincidence with the same surnames?" asked Hermione, as eager as ever to find out what was going on.
"Yes, yes," said Mary quickly. "I'm a daughter of James Potter. It's a shame to admit, but my existence is a result of his infidelity."
"So you're my sister?" asked Harry, astonished. His eyebrows were nearly blended with his hairline, he raised them so high.
"Well, yes I am. I can't believe that I was finally attend Hogwarts," said Mary, lowering her head. When she lifted it again, her cheeks were flushed. "I hope that we will be good friends."
She smiled sweetly at them and then door slid open again, revealing Seamus, Neville and Dean.
Mary was introduced to boys who looked at her shyly. She seemed shy and confident; it switched back and forth in Hermione's opinion. She also often used the loo.
Some time later Draco Malfoy made an appearance and Mary proudly showed association with Harry and his friends, sending daring looks towards the blonde.
Draco seemed to not be immune to her charms as he was less nasty than usual, practically not taking his eyes off her.
"You should take the boat," said Hermione to Mary, as they stepped out of train. The bushy-haired girl gritted her teeth from the cold rain
"I do not think so," replied Mary, as sweetly as before.
She flicked her wand and after that her clothes seemed to be repelling rain drops. Of course, she was immune to Peeves' water bombs which made Ron completely drenched. Hermione didn't know that spell, but it could provide useful in situations like this one.
Professor McGonagall escorted Mary to the Great Hall and she was sorted first.
The black haired girl, who was supposed to be Harry's half sister had spent a ridiculous amount of time with the sorting hat on.
Finally it shouted "GRYFFINDOR," and Mary approached their table, grinning.
As before, all eyes were set on her until she plopped on seat, next to Neville Longbottom.
"What took you so long?" asked Dean, who was sitting on her other side.
"Oh, the Hat couldn't decide which house I should be in. It wanted to put me everywhere at once," answered Mary, giggling.
After the feast, Dumbledore explained to Harry, Hermione and Ron that Mary Augusta Potter was indeed his half sister and lived in hiding. Harry seemed doubtful; mostly because it meant that he couldn't date this girl.
"Professor Dumbledore told us that she's your family, Harry, and he's the wisest wizard alive! How can we doubt in what's he's telling us?" reasoned Hermione, who was completely convinced that Dumbledore's words were always right.
They went to the Gryffindor tower together.
Parvati and Lavender had a great giggling session, when Mary turned out to be so shy that she magicked her curtains shut.
Of course the girls tried to peek in, but the spell charmed the material to be completely impenetrable. Probably also soundproof, as there was no noise from inside.
"Stop being mean, girls," instructed them Hermione and rolled her eyes. It was just rude to treat a new person like that. Especially the one which was the only living family of her friend.
A/N: Thanks to Artemis J. Halk for beta reading this chapter :)
I couldn't stop myself from posting a Mary-Suish character with a twist. Things are not as simple as they appear to be and I hope that you'll stay with me for some time to learn about it :)
