Katrina Lauren Weasley was not your average child. She lived with the Weasley's, and was the same age as Ron, however, she was adopted at a young age by the Weasley's at Molly's wish for a daughter, although they later had Ginny anyway. It was evident that she was adopted, as unlike the other Weasley children, she had jet black hair, which was quite a contrast to their bright red hair, she had skin that seemed to change colour from fairly pale to a dark olive, as did her eyes. One day they would be a deep ocean blue, the next, dark and menacing. Slightly green and brown, then an odd shade of orange and pink. She later found out that she happened to be a metamorphagus, able to change her appearance at will. This of course took time to control, and she had not managed to change the colour of her hair, just the length and shape. Naturally though, her hair was a wavy jet black that went to about 5cm below her armpit.
Another reason she knew that she was adopted was because on her 4th birthday, being the highly intelligent and inquisitive girl that she is, she saw her picture on her Dad's desk. Opening the file, she read all she needed to know. She confronted her Mother, and Molly Weasley did not deny it. Ever since, she has been know as 'Just another Wealsey' but she knew different. The whole household did, but she, unlike some others might have been if in her situation, was not upset. She understood about You-Know-Who, and understood that her real parents would never be found or identified, as they were most likely dead. It was a harsh reality, but still a reality.
So Katrina (more well known as Kat), continued her life as a Weasley. Kat was smart, intelligent, resourceful, and many positive attributes. However, as Molly would often point out,
"Katrina, your flaws outweigh your positive traits by a margin. I have said it once and I will say it again, it is not fun, nor entertaining, to pull pranks on other people! You and Fred and George are in massive trouble!"
As she would be brewing a potion to cure drowsiness, a simple, but effective potion that was placed in Percy's morning pumpkin juice.
Kat was always in trouble, whether it be for pulling pranks with Fred and George, 'accidentally' letting Charlie's pet toad loose, making fun of Ginny, or even spending too much time in her room. Therefore, Kat learnt to leave the house altogether, and walk a short 10 minute walk over the hills to a nearby clearing, with a small creak and trees for shade. It was here that she would write in her diary, sing, or even take a nap. It was here safe spot, where she could let the unruly magic inside of her do as it pleased.
But now, Kat was older. 10 years old to be exact, but not much had changed. Tomorrow, though, would be the one day of the year that was about her. Her birthday. Today was the 6th of July, and she had already planned the perfect day in her head. There were a list of things that she wanted to do, such as prank the family pranksters with her own, tar flavoured Bertie Bots Bean, write in her diary, set a snake loose in Percy's bedroom, and place Charlie's spider in Ron's room- a double whammy she'd say. But the one thing that she really wanted to do, was receive her Hogwarts letter.
Ron had received his on his Birthday, and they didn't say anything at the time, however Kat was sure that her parents were unsure as to if she would receive one or not, due to the fact that there was pretty much no record of her existence at all. They were worried and curious, but mostly worried of her reaction if it didn't arrive.
Finally, it was the morning of her birthday. She got up out of bed at 7:00am. An extremely rare occurrence, as she usually gets up at 10:00am. She went downstairs to the kitchen and added the final piece to a contraption she had spent a week on. She silently picked up her mother's wand and whispered a spell to set of the harmless, but noisy explosives. Colourful, loud fireworks went off, making their way up the stairs, resulting in some screaming, groaning and shrieking from different members of the family. She even swore she heard a loud yelp from Fred and George. Molly and Arthur apparated downstairs in an instant to a very smug looking Kat. Their breathing slowed and Arthur called to the upstairs children that everything was alright. Multiple feet could be heard making their way down the rickety stairs. Turning their attention back to Kat, Molly was the first to speak.
"Katrina Weasley, you scared all of us half to death! We didn't know what it was, who it was, where you were, but of course, it was just one of your little jokes! I..." She was abruptly stopped by the fact that Erroll, the family owl, had face-planted into Arthur's muggle coo coo clock, making it start to chime.
"So that's it's purpose! To chime that ridiculously annoying sound! Crazy thinkers these muggles..."
Kat however, was not interested in the clock. she was interested in what had fallen onto the floor, next to the twitching owl. An odd coloured parchment, almost yellow, with green ink sprawled on it reading;
Miss Katrina Lauren Weasley,
The oddly adjoining room on the 3rd level of,
Ottery St. Catchpole,
Kat turned it over and saw the Hogwarts logo printed into the parchment, as well as imprinted in the ink stamp. She smiled the biggest smile with pure joy as she opened the letter and began to read;
Hogwarts School of Witchcraft and Wizardry
Headmaster: Albus Dumbledore
(Order of Merlin, First Class, Grand Sorc, Chf Warlock, Supreme Mugwump, International Confed. of Wizards)

We are pleased to inform you that you have been accepted into
Hogwarts School of Witchcraft and Wizardry. Please find the enclosed list of all necessary books and equipment.

Looking at the list of books and equipment, she began to squeal with glee. Somehow, she had gotten in to Hogwarts. she did a little gig, of which Fred and George joined in. Molly, completely forgetting about why they were all downstairs in the first place, made a sudden announcement of a trip to Diagon Alley.
