Sup! I'm Pansy (not Parkinson I promise) and this is my first fanfiction! It 's based around my OC, Calla Lily Potter, who is Harry's twin sister (and her name is a flower pun kinda! I love flowers :). I really hope you enjoy this story, it's basically my life right now. But even if you don't (or even if you do) like it, please go check out the other stories by myself and my friends on this account please! We each have different ideas and writing styles and ways we interpret characters and blah, so you never know if you'll like one of the others!

Disclaimer: I am under the power of veritaserum and cannot tell a lie — I am not JK Rowling and do not own the characters or plot except for Calla and the changes I make.

LILY EVANS RULES! ~Pansy

The Grangers were a very happy, perfectly normal, little family. Mr. and Mrs. Granger were both dentists. They loved their job and made enough money to support their family.

They had one daughter by blood, Hermione Jean Granger. She was a normal little girl, who loved reading and learning things. She had bushy brown hair and brown eyes that were filled with wonder and beautiful brown skin. She was born to them on September 19 of 1979, and they loved her very much.

They also had adopted twins, Harry James Potter and Calla Lily Potter. They had messy black hair, bright green eyes, light brown skin, and each had a lightning scar on their forehead. They had arrived on their doorstep along with a note on November 1, 1981. The note said that their parents had died in an automobile crash and they had no relations left to care for them, so would Mr. and Mrs. Granger please do it. The note had also included their names and their birthday (July 31, 1980) and other perfectly normal and useful things to know.

Now, Mr. Granger had always wanted a baby boy, who he would be able to teach sports to and give his old Hot Wheels collection to. He did love Hermione very much, of course, but there was something about having a child of the same gender.

And Mrs. Granger, who was very compassionate and caring, immediately wanted to help these poor children. They had enough room in their house and they made enough money to support two extra children. Besides, Hermione had no friends, and siblings would be good for her.

So, the Potter twins became the Granger twins. Of course, the Grangers would never lie to them, so they grew up knowing how they came to live with the Grangers and what happened to their parents. But they loved their little family, and wanted nothing to change.

But, when their tenth birthday rolled around, life threw them a curveball.

KNOCK, KNOCK, KNOCK!

"Hermione, would you be a dear and get the door?" Mrs. Granger called from the kitchen.

"Yes, Mum!"

Hermione went and opened the front door, surprised to see a man with a long white beard standing there. Though his bright blue eyes looked angry, he gave her a smile.

"Hello, do Harry and Calla Potter reside here?"

"Mum!" Hermione called, without taking her eyes off of the strangely dressed man.

"Hermione, what's — Oh, hello," Mrs. Granger said, looking the man over. "May I help you?"

"My name is Albus Dumbledore. I am head of the adoption agency. I'm here for Harry James Potter and Calla Lily Potter. We have found that they have existing relatives."

Mrs. Granger felt her heart skip a beat. "E-existing relatives?"

"Yes," Dumbledore smiled. "A Mr. and Mrs. Vernon Dursley. Mrs. Dursley is their mother's sister. They have a son who is their age, and they are very eager to meet their niece and nephew."

Mrs. Granger didn't seem in control of her actions. She felt herself say, "I'll fetch the twins for you."

Then she felt her feet move through the house, up the stairs, to where Harry and Calla were playing an intense game of UNO in Harry's room. How could this man just come and take her children from her? But, she supposed she had to give them to their rightful family . . .

"Harry, Calla," she said quietly. "There's a man here to see you."

The twins exchanged confused glances — nobody ever came to see them! — but followed their adoptive mother back downstairs and where the man stood, talking with Hermione.

"Mum, you can't let him take them!" Hermione sobbed, running up to hug her mother tightly.

"Wait, this guy's taking us?" Harry asked, his voice laced with confusion.

"What's going on here?"

Mr. Granger had arrived home from work, and was confused by the scene before him. There was an old man in long robes standing just inside the doorway, and Hermione was crying and hugging her mother so tightly that she couldn't move. Harry and Calla stood off to the side, looking just as confused as Mr. Granger.

"Can I help you?" Mr. Granger asked the strange man, coming into the house and standing in front of his family.

Dumbledore was getting tired of explaining this, but he did once more. "I am head of the adoption agency, and Harry and Calla's aunt and uncle have been found. They now are in the care of their relatives. I am here to take them away."

"No!" Calla cried indignantly. "I won't go with you!"

"Calla," Harry said wearily. He obviously dealt with this a lot. "We can't just defy authority."

"And why can't we? I'm excellent at defying authority!"

"Harry, Calla, calm down," Mr. Granger said, trying to stop the twins from dueling.

Dumbledore wasn't really paying attention to what the family was saying. He was still angry that Minerva would do such a thing. When he had dropped the twins off on the Dursleys doorstep, he had never thought they wouldn't be there when he came to check nine years later. But apparently Minerva had moved them to a home she claimed was 'more fit to care for children' after he had left. Now he had to bring them back to their real family before they turned eleven.

He cleared his throat, causing the family to suddenly turn back to him. "Perhaps Harry and Calla should gather their things."

Hermione burst into fresh tears as her parents' shoulders sagged. Harry, not one for getting in trouble, began to ascend the staircase, but Calla stood her ground, glaring into the man's eyes. She looked like she would explode at any second.

Mrs. Granger put at hand on her shoulder. "Calla, we'll come visit. Now don't make trouble. After all —"

"Trouble doesn't make friends, I know," Calla sighed, flashing one last glare in Dumbledore's direction before stomping upstairs.

Petunia wasn't quite sure how, after nine years of her sister and brother-in-law being dead, she had suddenly been forced to take in her niece and nephew.

They had arrived, disgruntled, on her doorstep, along with an old wizard named Dumbledore, who explained everything. He had explained why this Granger family could no longer care for the twins, and why her family had to. He also explained that she had to care for them until they were seventeen, and then they weren't her problem.

Reluctantly, she agreed and even more reluctantly, Vernon agreed. They cleaned out the spare room, and the attic (you can't have a boy and a girl sleeping in the same room after all), and put a bed in each, and suddenly they had two more children.

Dudley put up a fight about keeping them, but he had no say in the matter. When he found that he could easily pick on Harry, his spirits perked up. Calla wasn't so easy. In fact, he steered clear of her. For a girl, she was downright scary.

Neither the Dursleys, nor the Grangers, had any idea that Harry and Calla would only have one year left of staying at Number Four Privet Drive. But just before the twins turned eleven, they would receive the surprise of a lifetime.
