Authors Note: Okay, after reading a few of these, I decided I'd try one of these myself XD. Probably won't be updated regularly though due to school commitments.

Disclaimer: I do not own the Harry Potter series or any characters therein; this is a non-for-profit fan work that is the result of one mildly insane teenage girl's love for the series (and her completely insane beta, who trims off the scary bits).

Thanks to my wonderful bet Lrona for all her help.

Summary: Harry has a twin sister Kaylee and after Harry's outburst at 'Aunt Marge' in the summer before their third year. Severus is sent to investigate what's happening in the Dursley house. What he finds is very disturbing. A Snape adopts Harry and Kaylee fic. Absolutely no slash. Warning: Child Abuse, Violence, CP, Other Cannon, AU.

List of Events:

Year 1:Same except when fighting the troll, Kaylee was comforting Hermione and they both told Professor McGonnagall they had gone after the troll, both find mirror of erised and both fight Quirrel etc. Both take an instant dislike towards Snape.

Year 2: Same except Harry and Kaylee both go down into the chamber where Kaylee is knocked unconscious and wakes up to her injured brother trying to stab the diary and she stabs it.

Extra Information: Kaylee doesn't like flying that much, they share a bed while at the Dursleys. They both have a magical connection (the feel each others consciousness and sometimes pain [only if the other twin wants them to feel it], but can't communicate with other), both also have scars.

Chapter 1: Punishment

'I shouldn't have done it Kaylee, I shouldn't have lost control like that, I know, but I just...snapped! I'm going to be kicked out of Hogwarts for sure! I blew up Aunt Marge for crying out loud! Now they'll come, snap my wand and I will be stuck here in this horrible place all on my own while you go off to school. How could I have been so stupid?'

Harry and Kaylee were sitting in their room, they had tried to run away once Harry had blown up Aunt Marge but Vernon had grabbed hold of Kaylee as they were running out the door so Harry was forced to stay behind, he just couldn't leave his sister to their mercy. Uncle Vernon had quite literally thrown them into their room and locked the padlock on the door behind him, there was no escaping. Even if Harry had had the time to pick the lock, their uncle would be able to grab one of them easily as soon ass they made it down the stairs. As their uncle had left the room he had promised them that they would pay for what they had done. The twins didn't like the sound of that. They knew what Uncle Vernon's punishments were like, and knew that how ever much regret they were feeling now, they would be regretting it even more when he uncle came back.

'Calm down, Harry,' soothed Kaylee, 'everything is going to be okay. I'll tell the ministry that it was me who blew up Aunt Marge; I've never used underage magic before so they'll probably just give me a warning like they did when Dobby levitated that cake. And as for Uncle Vernon, we've lived through his punishments before; we can live through it again!'

Harry started to calm down, but the calm did not last long for either twin. They both heard the unmistakable sound of their Uncle trudging up the stairs. In the backs of their mind they had been mentally preparing for this. They had even gone as fare as to worry what was taking him so long, he was usually prompt with their punishments.

'Kaylee, stay behind me. This whole thing is my fault; I don't want you getting hurt for this.'

'But Harry! You took it for me last night!' Kaylee begun but her brother silenced her argument telling her that if he had had enough he would tell her and that if they kept talking now, it was just going to make their uncle angrier. They arranged themselves as planned and mentally prepared for what was to come.

The door swung open with a resounding bang and the smell of whiskey wafted into the room. The twins knew what this meant and cringed inwardly, it was going to be worse than they had originally thought.

'Freaks!' he spat at the twins, his voice dripping with venom, quiet but deadly. 'No! It's not enough that you used your freakishness on my dear sister! But then, you just had to take it one step further!' The twins looked at each other fearfully. What was going on? What had they possibly done while being locked on their room?! 'You come into my house, you ungrateful little brats, and we feed you, clothe you, give you a place to stay out of the goodness of our hearts and this is how you repay us! You use your freaky little voodoo magic to get me fired! Well I'm telling you both. You'll pay for this; you'll pay for this dearly!'

At this point, Vernon grabbed harry around the neck, punching him in the face and throwing him to the ground. From there he started kicking and punching him while Harry rolled up into a little ball, trying to protect his head. Harry remained silent throughout all of this. They knew from experience that if they made a sound during their punishments it only made it worse. After all, it wouldn't do for the neighbours to hear, they might start asking uncomfortable questions.

As the shower of blows rained down on Harry, Kaylee sat there until she could take it no more. The connection she shared with her brother let her feel that he was starting to loose consciousness. She had known when Harry had said it that he had no intention on asking her to step in, he would rather remain being beaten while unconscious than let her hurt. To hell with what he wanted, she threw herself in front of Harry, protecting him from the never-ending blows. She felt a sharp pain in her right arm and over the sound of steel capped boots hitting her soft flesh she heard a distinctive snap. She knew it had broken. She still did not make a sound. As the blows kept raining down on her, she cradled her injured arm as best she could and slowly followed her brother into the depths of unconsciousness.
