A/N: So...I'm not sure about the name I gave my main character...but this idea's been growing in my mind for a really long time now. I finally decided to write it down, so here it is ^^

Leave a comment? Review? Are the characters OOC? You feel like flaming me? I just want to know what you guys think about this ^^ if anyone really likes it, I'll continue writing...if not...I guess it depends on my mood whether or not I continue writing it.

Disclaimer: I'm gonna put this here but the disclaimer is on my profile anyway. I don't own Harry Potter. Anything you don't recognize though (ex: Icy)...that's mine ^^

awaiting your reviews~ Aoi-kun

They weren't related. Not really. They knew that. After all, they didn't look alike at all, but still, they were the closest siblings around. Icy and Harry that is. Harry was a skinny kid with unkempt black hair that refused to lie neat no matter what he did to it, glasses, emerald-green eyes, and a lightning shaped scar on his forehead. Icy was a thin girl with slightly wavy black hair with a blue-ish tint to it that fell down to about mid-back cut into three layers (straight bangs, then to chin-length, and finally the rest of her hair that just hung down her back), glasses, and silvery-white eyes.

When they were younger, Aunt Petunia and Uncle Vernon had told them that Icy had been adopted by the Potter's before they had died in the car crash. It hadn't come as a surprise to the two children; they had doubted that they were blood-related since they could remember anyway. Instead of tearing them apart though, that fact just seemed to bring them closer.

Harry was the older of the two, by almost two years. Icy was the more innocent of the two, Harry having shielded her from most bullies at school and torments of living with the Dursley's. And Icy was also severely dependent on her older brother. She wasn't shy, no, far from it, but she chose not to speak. She was also very smart for her age, seeing things and understanding things at a faster pace than many of the others around her, even adults at times were astounded by her perceptive skills. This only helped to fuel Harry's overprotective nature. The adults wanted to take Icy away, to study her, to see what made her so smart…but he refused to let them. He knew Icy was scared. She told him so oftentimes enough.

She confided in him what she couldn't to others and he was like her lifeline, supporting the small girl even when he could barely support himself. So, when a series of strange events started to happen around the two of them, the two found themselves needing each other more than ever.

Then the letters started appearing.

It had started off normal enough. Ever since getting his uniform Dudley had taken around to carrying around his Smelting's walking stick, banging it on anything he could reach. Harry was on the receiving end of many of those hits, between the ones aimed at himself and the one's aimed at Icy, Harry really had to have fast reflexes.

So, when they entered the kitchen for breakfast, Harry was quick to pull Icy out of the way as the walking stick whistled through the air, right where Icy's arm would have been had Harry not moved her. Icy's small fingers curled into the back of Harry's shirt as she peered over Harry's shoulder. Her black-rimmed glasses were starting to slide off the end of her nose and she ducked back behind harry to fix them.

Harry sat down at the table, Icy sliding into a chair next to him. The family ate in silence after Aunt Petunia set the table. A soft thump came from the front hallway.

"Dudley. Go get the mail." Uncle Vernon told his son.

"Make Harry get it."

"Harry, go get the mail."

"Make Dudley get it."

"Hit him with your Smelting's stick Dudley."

Harry ducked the swing, grabbing Icy's hand and pulling her out with him. Icy stumbled a few steps behind Harry, who slowed down to make sure she was okay before the pair approached the small pile of letters on the floor. As the two bent to pick up the envelopes, the each gathered half in their hands. They straightened back up before sifting through the mail. They froze simultaneously.

In Harry's hand was a letter with his exact address, right down to his cupboard. And in Icy's hand was the same thing, only it had her name instead of Harry's. The two blinked in surprise at each other. Who would send letters to them? Least of all know where they slept?

Harry took the rest of the mail from Ivy's hand and took her free hand as she continued to stare at her letter unblinkingly.

"Wait Harry we shou-" She stopped speaking as soon as they entered the kitchen. Her mouth just snapped shut. Harry turned his head to give her a questioning glance as he handed the mail over to Uncle Vernon. She shook her head and slid back into her seat, Harry doing the same. As Uncle Vernon listed off what was in the mail, Harry began opening his letter, Icy chose to slide her's into the pocket of the overlarge pullover that she wore. And not a moment too soon either.

"Dad! Dad! Harry's got a letter."

Uncle Vernon looked up and quickly took the letter away from Harry. "Who would write to you boy?" he sneered. As Harry demanded that he give it back though, Uncle Vernon had already turned the letter over and had caught sight of the seal. His face immediately turned an ugly shade of purple as he spluttered.

"P-Petunia! P-Petunia!"

Icy took Harry's hand into her's and shook her head minutely. He understood what she meant and when Uncle Vernon threatened to throw them out if they didn't leave, he quickly pulled Icy out behind him. She patted her pocket to make sure her letter was still there as Dudley pressed his eye to the keyhole. She'd open it later.

At that moment the door opened again and Uncle Vernon glared at Harry and Icy. "Go to your cupboard. Dudley…just get out." Harry looked like he was going to protest but Icy pulled on his shirt before he could. They retreated into the small space that had been designated as their's.

"Why wouldn't you let me get my letter back Icy?" Harry inquired with a slightly irritated expression on his face. Icy blinked her almond-shaped eyes and shook her head. "Whoever sent you that letter had to have sent me the same one right?" Harry realized that Icy's letter hadn't been confiscated when his was and he nodded.

Icy took her letter back out of her pocket and slit it open neatly. Inside were three pieces of heavy looking paper…parchment maybe? She pulled them all out and unfolded the first one. Her eyes skimming over it.

"School of…" She trailed off as she continued to read.

"Special case…" she murmured. Harry studied his sister's expression as she read in the dim lighting and his curiosity mounted as her brow furrowed.

"Is that what everything that happened was…?"

Now he was lost. What was she talking to herself about? She moved onto the next piece of parchment, only skimming it before putting the two down and opening the third one.

Harry picked up the two she had put down and his eyes were instantly attracted to the parchment header.

"Hogwarts School of Witchcraft and Wizardry…" His eyes narrowed at the parchment before he put it back down, not even bothering to read the rest. As he looked back up, Icy was still staring at the third piece of parchment. The only change in her stance was the hand that had crawled up and wrapped around the ring she always wore on a chain around her neck.

"What is that Icy?" Harry reached out to take it from her but before his fingers could even brush the parchment, Icy had folded it up and tucked it into the pocket of her jeans. "That one was personal…" she whispered, a strange emotion clogging her voice. Harry couldn't place what it was though.

He let it slide though as he waved the other two pieces of parchment. "Can you believe this? Are they joking? Do they actually expect us to fall for such a stupid joke?" Icy's eyes flashed slightly, Harry couldn't have been sure though in the dark space.

"A joke…is that what you think this is Harry?"

Icy's serious tone, even softened as it was by her childish innocence, made Harry pause momentarily. Then he shook his head. "Icy…you know better than this, the Dursley's are probably just trying to make fools of us."

Icy averted her eyes and nodded. The sound of paper ripping had her jerking her head up quickly though.

"Harry-!"

There was no point though. It was too late. He had already shredded her letters. Well…at least she still had the one in her pocket.

"You overlooked an important fact though Harry…Uncle Vernon seemed just as surprised as we did when he saw the letter. We both know he isn't that good of an actor." Icy murmured before gathering up the bits and pieces of her letter and dropping them all into the trash bin.

Harry was silent as the information sunk in. "Oh…I'm sorry Icy…I hadn't thought-"

"It's fine Harry." Icy closed her eyes and lay down, curling into a small ball. Harry placed a hand on her head and ruffled her hair lightly. "We'll be fine Icy. We'll get out of here someday."

Yet, even if Harry had claimed that it was all a joke, he couldn't deny his own curiosity, especially whenever he would catch Icy sneaking glances down at the pocket he knew she kept the third part of her letter in. She still hadn't told him what it was about, but it made him wonder what could have possibly been within his own letter. That's when things started going crazy.

Letters for Harry and Icy kept coming. Through slits in the doorway, rolled into eggs, you name it. Finally it was the weekend. More specifically, it was Sunday. And as they all knew, there was no post on Sundays. Uncle Vernon seemed especially pleased of that fact as he sat smiling to himself in his armchair. Or at least until he got smacked right in the face by a letter that had whizzed down the chimney.

And it all went downhill from there. For Uncle Vernon that is. Letter after letter kept shooting out of the chimney. Uncle Vernon gave a mighty roar and had to literally throw Harry out of the room, Icy following after, to keep them from grabbing any letters. As he slammed the door to the living room shut, Icy sat on the floor, her legs to her sides, rubbing at a spot on her head that she had bumped when Uncle Vernon had tossed her out after Harry.

"It's useless." She murmured. As Harry stared at the door to the living room, he wasn't sure if it was him she was talking to, or if it was Uncle Vernon. It was one of those things that she seemed to do a lot, speak in ambiguous sentences.

Even as he wondered about the meaning behind Icy's words, Uncle Vernon wrenched the door back open, scaring Harry, Dudley, and Aunt Petunia in the process. He did look awfully frightening, half his moustache having been pulled out in his frustration. Icy merely regarded him with an unreadable expression on her face.

"Go. Pack some bags. We're going out." He managed out. The four other members of the family exchanged looks before parting to quickly do what had been commanded.

A half hour later, all five were packed into Uncle Vernon's car, Dudley sniffling. His father had yelled at him for holding them up as he tried to stuff electronics into a duffel bag. All was silent as Uncle Vernon drove on. He didn't seem to have a clear destination in mind though, as he kept taking random turns, muttering to himself in the process. After watching the scenery pass by for an hour or two, Icy's head fell onto her brother's shoulder and she fell asleep.

She was awoken by someone shaking her shoulder.

"Icy, wake up."

Icy cracked her eyes open to meet Harry's eyes. He quickly moved his head back so that she could sit up to see where they were. It was a small hotel inn kind of thing. Uncle Vernon got them a room and Harry and Icy ended up sleeping on the floor. Dudley having gotten one bed while Aunt Petunia and Uncle Vernon shared the other. It wasn't all that uncomfortable though, at least they had a few blankets to use.

During breakfast the next day, the manager approached the group as they sat eating a cold breakfast of toast and tinned tomatoes.

" 'scuse me, but any of you's 'arry and Icy Potter?"

The two children jerked their heads up.

"Only, I gots about a 'undred of these by the fron' desk."

Then he held up an envelope. Harry jumped up for it at the same time as Uncle Vernon did. The big man knocked Harry's arm aside and cleared his throat, the manager's eyes nearly bugging out of their sockets. "I-I'll take them."

Harry sat next to Icy, once again back in the car, grumbling under his breath. Icy softly took one of Harry's hands into both of her own, lacing their fingers together before smiling sweetly up at him. His fury melted away and he returned her smile, raising a hand to ruffle her hair once again. "Thanks Icy…"

The next time they stopped they were next to what appeared to be an ocean. Spray from the waves hit them as they all clambered into a small waterlogged boat. Uncle Vernon picked up the oars, setting the long thin package he was carrying down under his seat. Icy stared at the horizon as the made their way towards the house precariously perched on rocks in the middle of the body of water.

"Here."

Each person was given a bag of chips and a banana for dinner. After that, Aunt Petunia and Uncle Vernon retreated to the "master" bedroom to sleep on the only bed in the house. Dudley was given the couch with the warmest blankets that Aunt Petunia could find. Icy and Harry were given a single moth-bitten blanket to share between them.

Together they found the softest bit of ground they could before lying down. Icy cuddled into Harry for warmth, the small boy looping his arms protectively around his sister as the two lay, awake, under the thin blanket. None of them could have explained it, why the both of them remained awake, just staring up at the dark ceiling.

There was a small light, barely a glow, coming from Dudley's watch, which hung over the edge of the couch's armrest. Judging from that, it was almost Harry's birthday. Icy made a thoughtful sound before turning onto her stomach, breaking the hold Harry had on her and reaching past the blanket with a small hand, dragging a small finger through the dirt. It took a few seconds before Harry joined her, blinking at what she was drawing.

It was a simple cake really; the one Icy drew in the dirt. She carefully wrote the words 'Happy Birthday Harry' on the cake before drawing eleven candles with flames on it. Then the two children turned their eyes to the watch, counting down the seconds to Harry's eleventh birthday.

"Make a wish Harry…" Icy whispered. Harry met her gaze before smiling softly at her and then blowing at the candles.

A bang reverberated through the entire house, causing Harry and Icy to sit up, Dudley falling off his couch, while Aunt Petunia and Uncle Vernon ran out of the other room. Uncle Vernon had a rifle clutched in his meaty hands that explained the thin package from before. Another bang. And then another and the front door fell in to reveal a rather large man standing in the now gaping hole, the storm raging behind him.

He stooped to enter, bending over to pick up the door and setting it back in its frame before turning back to the five occupants of the room.

"Hello."

Silence. Just for a moment. Enough for Icy to stand and tilt her head slightly, her pale gaze assessing the big man as Harry scrambled up to place a hand on her shoulder. "Who are you?" she asked in a soft voice.

The man's beetle black eyes met hers and she could see the kindness radiating off of them. He moved closer and sat down on the couch, Dudley making a sound of fright as he ran to his parents. "Harry an' Icy… Las' time I saw you two, you was only babies." He moved his gaze to Harry. "Yeh look a lot like yer dad, but yeh've got yer mom's eyes."

Uncle Vernon made a funny sound. "Get out of here! This is breaking and entering sir!" Uncle Vernon suddenly shouted, waving his gun around. The man turned and reached out a hand, easily twisting the gun out of Uncle Vernon's hands and twisting it into a knot.

"Ah, shut up Dursley, yeh great prune."

He then returned his attention to the children before him, this time addressing Icy. "You, on the other hand, look a lot like yer mum. I would've thought you was her if I didn't know better." As Icy took the time to process this information, the great man reached into his pockets and started emptying things out of his pockets, mentioning something about having a present for Harry, it being his birthday and all.

He finally produced a somewhat squashed box and handed it to Harry. Harry opened the box hesitantly and examined the sticky chocolate cake, birthday wishes written on it in green ink. When Harry looked up, Icy could see the confusion dancing in his eyes. He probably meant to thank the giant but instead he asked, "Who are you?"

The giant chuckled before introducing himself as Rubeus Hagrid, Keeper of Keys and Grounds at Hogwarts. Hogwarts…Icy glanced down at her pocket again, sliding a small hand into the pocket and withdrawing the letter, holding it loosely in her hands as she tuned out the rest of Harry's and Hagrid's conversation.

Hogwarts… maybe she'd get some answers there. Who her parents truly were…why they hadn't wanted her…and how she had ended up with the Potter's. Everything she'd always wondered about and that she'd never get answers too... and maybe… she could find out who that boy was. The boy whose name was etched into the inside of the ring she wore on her necklace. Harry didn't know about it of course. She'd found it by pure accident actually. Icy was prone to playing with the ring whenever she found her hands idle, so she found the irregular feeling on the inside of the ring while she was playing, it was nearly invisible to the naked eye but Icy had been able to somehow read the name etched into the band. She'd never brought it up with the Dursley's though. Don't ask questions…that was one of the many rules she'd been quick to pick up on during her stay in the Dursley household.

"ALL WHAT?" Hagrid's voice suddenly thundered, breaking Icy from her musings. He leapt off the couch and turned on the Dursley's who had taken to cowering against the wall. Icy edged closer to her brother, grabbing a handful of his shirt and holding on loosely. She zoned out again as Hagrid continued to roar at the Dursley's before explaining things to Harry. Things that Icy had already figured out when she'd first read her letter.

Once again she was broken from her musings, this time by a letter being held out in front of her. She accepted it with a small smile to the giant and opened it simultaneously with Harry. It was her acceptance letter. A new one.

"What do they mean by "we await your owl"?" Harry asked curiously.

Hagrid clapped a hand to his forehead before pulling several items out of his pocket. A live owl was among those items. Icy reached out a hand cautiously and pet the bird as Hagrid scribbled out a letter that Harry was reading upside down. After he was finished with his letter, Hagrid gave it to the owl before throwing it out the door and into the raging storm. Icy felt a small pang of sympathy for the small bird as she thought about how its journey through the raging storm would most definitely not be a pleasant one.

As Uncle Vernon stepped forward to voice his objections, Aunt Petunia to shriek about her sister, and Hagrid to thunder over all of them, Icy once again took her brother's hand and ran her fingers over the back of it, the conversation… rather, the shouting match… taking a backseat in her mind, just a small buzz in the back of her consciousness.

She listened with faint interest as Hagrid went on and on about Voldemort, or You-Know-Who, and about how he had been the greatest dark wizard of his time and how he had fallen by Harry's hands. "I told you you were great…" Icy murmured, standing slightly on tiptoe to reach Harry's ear. Hagrid gave her a funny look before continuing on with his speech about Hogwarts and how Harry would fit right in.

That is until Uncle Vernon interrupted again. Icy sighed as Uncle Vernon exploded. That man never could learn when to just shut up. It was then that Icy was given the first glimpse of magic she was actually paying attention to. A large grin split her lips as Dudley howled in pain, clutching at his bottom, where a pig's tail had sprouted.

"Meant ter turn him into a pig…he was so much like a pig…wasn't much else left to do…" Hagrid said ruefully. Then he went into an explanation as to why he wasn't allowed to use magic. Icy would've paid attention but it was getting really late…in fact it was really early in the morning now. Her eyes started fluttering and despite all her best efforts she couldn't keep them open much longer. Her grip on Harry's hand loosened until her hand fell and she lost her balance, almost falling to the floor if not for Harry's fast reflexes. He caught his sister and slowly lowered her onto the floor. Hagrid took that as his cue.

"We've got lots ter do tomorrow and it's gettin' late." he took off his coat and threw it at Harry. "You two can kip under that. Don' mind if it wriggles. I got a couple o' dormice in one o' the pockets."
