A/N: This is my second fan fiction, but my first for Harry Potter. My laptop had to go away and get repaired, resulting in a new hard drive being installed; meaning that I lost all my files and pictures and everything. I haven't been able to get back into the swing of rewriting the chapters for my other story, so I thought I would try writing a new one instead. I got this idea when I was at college doing my business plan (why we need to do a business plan in animal care I will never know); I had to write it down, and I haven't been able to get it out of my head since. Enough of the rambling; I hope people will like this story more than my other one.

Thank you to my two beta's court2010 and lovegoodpotter (I would also like to thank my new beta Lastnights regret)

I do not own anything Harry Potter related or anything that is otherwise publically recognizable.

Summary

Harry is The-Boy-Who-Lived, but he also has a non-identical twin sister, Harriet, who is also The-Girl-Who-Lived, who went missing the night that Voldemort attacked the Potter's home. What will happen when her and Harry both arrive at Hogwarts? Will their upbringing make them the best of friends or the worst of enemies? And what happened to Harriet all those years that she was missing.

Prologue

In the aftermath of the attack of Lord Voldemort, on the tragic Halloween night in Godric's Hollow, there amongst the ruins, were the cries of two infants—one boy and one girl. They were both siting side by side holding onto each other. The boy had a hold of his sister's sleeve, and he had a finger caught in the bracelet around her wrist, he wore an identical bracelet. The girl was holding onto her brother's top in a way of reassuring each other that they were not alone. They both sat in the collapsed mess of their large cot*. A big smoky mess filled the air around them instead of their brightly coloured room which they were used to. The bodies of their parents lay discarded; their father on the stairs, and their mother in the same room as them; both parents were dead.

There was a shuffling and crunching noise of someone walking through the rubble towards the cries, and a woman of around 28 years old appeared from around the crumbling wall; she wore a nurse's outfit as her Halloween costume, and her auburn hair was held back in a long ponytail. She looked around and spotted the two crying children; instantly she rushed over to them, careful to avoid their dead mother.

Quickly, she checked over them, other than a lightning bold shaped wound on opposite sides of their heads (the boy on the right side of his forehead, the girl on the left side of her forehead) they seemed alright. She never took the time to think about how odd it was for both infants to share the same shaped wound of identical sizes and depths.

The woman lifted the little girl from the crib first, untangling the little fists, knowing that she would be unable to carry both children at the same time over the dangerous rubble; she did not want to risk the chance of falling and not being able to catch herself without hurting the children. She decided to take the girl and come back for the boy as soon as she had given the girl to her husband, who was making his way over at that very moment; it would only be a minute that she was away from her brother. Taking a last look at the little boy, with a brief whisper promising she would be back she disappeared behind the wall again.

By the time the woman had turned the corner and her husband was insight, she gave him the little girl; she had been unaware that a man had appeared at the fallen house. The man was slender with dark hair, and he was dressed in a dark cloak; he rushed into the house as soon as he arrived, stopping first to check the pulse of the man lying on the stairs, when he found no pulse he cursed and ran up the stairs. After checking in a couple of rooms he arrived at what used to be the children's bedroom, seeing the woman on the floor her ran to her, and went through the same process as he had for the man on the stairs, with the same results he then stood and looked around the room.

He noticed the now silent little boy in his crib; he rushed over to the boy and checked him quickly for any major injuries, finding only the cut on his head, he gently picked the boy up hugging him to his chest, trying to stifle a sob of relief that at least one of the family of four had survived. Shifting the boys weight into one arm, the man started searching frantically for any sign of the little girl who he knew must have been there somewhere, after a while he stood silently listening for any breathing. Not a cry was heard; he was met with only silence.

Walking back out to the street, the man sat heavily on the curb, hugging the small child to him as if he was scared that the little boy was going to disappear. A second man appeared this man was the largest man you probably would ever see; he stood much taller than any other normal person, and was wider as well. He had a tangled beard and tangled dark hair, though despite his massive appearance, he did not seem scary, or intimidating quit the opposite actually. The giant of a man sat down next to the man and child and they seemed to be having a conversation.

By this time the woman had turned back and was just heading around the corner to return to the house. She ducked back, peering around the corner from her hiding place. From the angle in which the woman could see the two men from, she did not want to approach the house again. She feared that these people would notice her; these men could be the killers that just destroyed the house and killed the twin's parents!

She stood watching around the corning, the giant of a man jumped to his feet and bounded into the house and from the movements, she could see from him through the blown out windows, and from the collapsed walls she managed to determine that the man was searching, probably for the little girl who was now sleeping soundly in her husband's arms.

With a sigh of resignation and a whispered apology towards the boy still in the crib, the woman turned and headed back towards her husband, giving a quick explanation of why they were leaving without the second child. Before they both turned their backs on the ruins, the little boy and the two men walked away, never to look back on the house at the edge of the town, and to not talk about the house or the people who were there for many years to come.

A/N

Ok so I've decided to add a list of all of the British and Scottish words or phrases that have been used just in case anyone who is not British does not understand. I've had help from one of my beta's, court2010, who is not British, so we should get them all. This should be happening at the bottom of every chapter. So please let me know what you think and if it helps at all.
