Disclaimer: I do not own the Harry Potter books That's what J.K. Rowling is for.
It was a bright, sunny, August day in New York City. I was getting my school things ready for my fifth year at Gothica School of Witchcraft and Wizardry when my adopted father Sirius Black came into my room.
My dad was a very handsome man. With the cover story that the Order of the Phoenix was using my dad had to temporarily age his face. Apparently twelve years in Azkaban did a lot to one's youth, at least, that's what Mad-Eye said.
"Well, seems as if there's been a change of plans, sweetheart," he said as he surveyed the mess growing on my bedroom floor. "The Order has decided that you being in hiding is beginning to be pointless and they, we, want you to finally meet your brother." He smiled as I got up from my organizing with a huge grin on my face.
"You mean I'm going to meet Harry?" He confirmed my question with a nod and I ran to hug him. He returned my hug and kissed my on top of my head. He knew I'd been waiting for this my whole life.
It all started when Voldemort targeted my family. My mother and father were Lily and James Potter. From what my dad tells me they were brilliant. Well, when my parents found out about our family being in danger, my mother was pregnant. Not just with Harry like everyone thought, but with twins. On the night my brother and I were born, we were christened right away. We became Harry James Potter and Aurora Lily Black. My parents saw it important that they gave me to Sirius and named him Harry's godfather since Voldemort was only after "a boy born at the end of July", even though me and Harry looked exactly alike as infants; same jet black hair, same emerald green eyes. So Sirius and I went into hiding in the most highly populated city in America, and Harry and my parents waited to die in Godric's Hollow. Obviously my brother was the only one that didn't die and everyone knows the rest.
Dumbledore and the rest of the Order devised a cover story that Sirius went after the rat that betrayed my parents Peter Pettigrew, and they sent him to "Azkaban". The person that really went there was Sirius's brother Regulus to protect him from Voldemort when he switched sides.
Now, I've always known I had a brother and Sirius always made sure that I knew who my parents were and what wonderful people they were. I was always reminded that I looked like a complete mixture of my parents with my father's jet-black hair with with my mother's curls along with her gem-green eyes. I had a happy life living with Sirius in our lavish apartment on Park Avenue (AN: Link on profile page). When I was eleven I got my letter from Gothica as expected and I'd been going there up until the last day of my fourth year.
At Gothica there were no houses. We all wore one uniform in one color scheme (AN: Link on profile of A's uniform), and there were no rivalries. It was nice. Our uniforms were made to look like common private school uniforms because the school was located in the heart of New England where there was Muggles galore. At school I was good at many subjects, specifically potions thanks to my private mentor Severus Snape, much to the dismay of Sirius.
"So, continue packing your things, and let me know when you're finished so we can head to London." My dad said gesturing towards my mess.
"Is Harry already at the manor?" I asked, still completely excited.
"Yes, he's been there for a few days now. Just remember Aurora; he has no clue that you're his sister. I'm sure he'll get a good idea once he sees you, but stay on the down low until I tell you it's time. Got it?" He gave me a stern look. He knew about the mischievous streak I inherited from my biological father.
"But Dad, does he know that Azkaban and everything was a hoax?" he looked at me exasperated for a moment, but still answered my question.
"Yes, he just doesn't know why. Now that Regulus is free and my name's been cleared, it's safe for him to know. Now answer my question, young lady." I couldn't help but smirk at his expression because he was having trouble suppressing a grin himself.
"Of course, Daddy. I don't want to mess things up, anyway. You all have gone through too much trouble already." With that my dad left me to finish packing as I daydreamed of what my brother was like.
A/N: So I hope you like it! The idea's been in my head for a few days now and I just felt the need to write it! REVIEWS are greatly welcomed!
