A.N. Hi everyone, this is my first story so take it easy on me. I wrote it for fun and thats all. If you have some constructive critism I will take it in stride but if you review to just be plain mean I won't even look. If you have any questions about the story, that I will try to answer in a later chapter. Also if you need a visual on Andi's looks, just imagine the Switched at Birth actress Vanessa Marano, only with blue eyes. She would definitely be the person to play my character if she was real. Okay then enjoy the story.

Disclaimer: I do not own Harry Potter or Charmed, or even Andi's looks. The only thing I own is the plot and Andi (well her character).

Andi's Powers: Telekinesis, Astral Projection (can use powers even in astral form), freezing time (advanced to freezing good witches), molecular combustion, premonitions, empathy, flight, force field and hydro kinetic.

July 1st

It was a bright and sunny summer day in San Francisco. All was peaceful, especially in Halliwell manor, home of the Charmed Ones. In one of the bedrooms, a girl was fast asleep. The door opened and a four-year-old girl ran in. She climbed on the bed and started to jump on the sleeping female.

"Wake up! Wake up!" The child shouted between jumps. With a start the older girl awoke. Suddenly with a flick of her hands the little girl froze in midair. When the other girl realized what she had done she quickly flicked her hands again.

"For Pete's sake, Melinda Halliwell! What did you do that for? You're lucky I just froze you." The older girl scolded as Melinda landed on her bed with a thump.

"Sorry Andi, I just wanted to be the first to wish you a happy birthday." Melinda apologized. Andi smiled and hugged Melinda.

"Okay, I will let it slide this time 'little sister'. Now get out of my room so I can get dressed." At this Andi gave Melinda a shove towards the door.

"Okay, just hurry up and come down so we can eat. Mom's making all of your favorite foods."

"Alright I'm hurrying!" Andi laughed as she pushed Melinda out the door and closed it after her. She crossed the room to her dresser and looked in her mirror. An eleven year old girl stared back at her. She had neat curly black hair past her shoulders, bright blue eyes, and a soft milky complexion. The only thing odd about Andi was her size. Instead of the size of normal children her age she was the size of a small eight year old. 'Happy Birthday to me.' She thought. She quickly changed into a white t-shirt with the words 'Too cool for you' on it, blue jeans, white socks, and white sneakers. She then reached into her jewelry box for her gold necklace that said Adrianne, which was her name. Andi was just her nickname which you got when you took out some of the letters.

After she put on the necklace she ran downstairs to the kitchen. Her aunt Piper was cooking. Her uncle Leo was at the table reading today's newspaper. Her 'brothers' eight-year-old Wyatt and seven-year-old Chris were wrestling in the living while Melinda was reading a book nearby.

Wyatt, Chris, and Melinda weren't really her siblings. They were her cousins. Andi's mother Prue was originally the oldest of the Charmed Ones, but she died in a demon attack when Andi was only one. Her father Andy Trudeau died before she was born. Since their deaths her aunts Piper, Phoebe, and Paige had helped raise her. Since she lived in the manor with Piper's family she was closer to Piper's children, considering them siblings instead of cousins. Leo was the first to spot her.

"Hey, there's the birthday girl, good morning Andi." He greeted.

"Wyatt, Chris, stop fighting and wish your cousin a happy birthday." Piper instructed. The two ignored her and continued fighting. Andi smiled and when they rolled towards her she jumped into the fray easily subduing the two in a matter of minutes.

"Don't you two have ears? Listen to your mother." She ordered.

"Sorry Mom. Happy Birthday Andi." The two said at the same time.

"It's alright boys. Andi, nice job getting things to listen, you'll make a great leader of the next generation of Charmed Ones one day." Piper complimented.

"Thanks, Aunt Piper." Andi said. Suddenly there was a flurry of blue lights and a big red heart. When those faded standing there was more of the family members. Phoebe and her husband Coop, with their children, five-year old Prudence, three-year old Chloe, and two-year old Emmy. Next were Paige and her husband Henry, along with three- year-old Henry Jr., and one-year old twins Patricia and Penelope. Also with them was Piper and Phoebe's father Victor and Billie, a family friend.

"Happy Birthday!" they all chorused.

"Thank you!" Andi replied.

"Breakfast!" Piper called and the family all headed to the dining room to eat.

Later that day everyone was in the living room chatting and waiting for the birthday cake. Andi had already opened her presents. From Piper's family it was a set of books and jewelry, from Phoebe's family it was a dark purple messenger bag with the triquatra symbol in silver studs on it in the front and two sketchbooks, from Paige's family it was new clothes including accessories, from Victor it was a new set of art supplies and stand for her art work, and from Billie it was a silver butterfly clip and a lot of accessories for her hair.

Suddenly there was tapping by the window near Andi's head. She turned around to see a brown barn owl at the window with a letter in its beak. She opened the window and the owl flew in. She took the letter out of its mouth. It was addressed to her and had a strange seal on it. The owl flew off but went unnoticed. She opened the letter.

Hogwarts School of Witchcraft and Wizardry

Headmaster: Albus Dumbledore

(Order of Merlin, First Class, Grand Sorc., Chf. Warlock, Supreme Mugwump, International Confed. of Wizards)

Dear Miss Halliwell,

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

Term begins on September 1st. We await your owl no later than July 31st.

Yours sincerely,

Minerva McGonagall

Deputy Headmistress

After reading through the letter and skimming through the supplies list, Andi looked up at her family and asked, "What's Hogwarts?"

"We don't know." Piper answered, "This is the first we've heard of it."

"I'll go check with the Elders." Leo said and orbed away after everyone nodded. Soon after, he returned. "Okay, according to them we are not the only magical world out there. There is another that has wizards and witches and some of the creatures we have seen over the years but they are different. Wizards and witches are different there; they use mostly wands to channel their magic. Hogwarts is one of the schools young witches and wizards can go to for seven years to learn how to control their magic."

"You mean like Magic School?" Prue asked.

"Yes, and it's apparently one of the best. But…" Here Leo trailed off.

"But what?" Phoebe asked.

"It's not here, it's in Europe, Scotland to be precise.."

"What?!" Everyone who could understand exclaimed.

"But why would I be invited then?" Andi asked confused.

"Because our two worlds know each other exists, but we are not close. The heads of the magical communities there have spoken to the Elders and they think that if a witch from our world could go there on a trial basis it might be a step in bring our worlds closer together. Apparently you, Andi were chosen for two reasons. One because of your powers you possess great magical potential. And two because you are not the only member of the Warren line to be invited to attend,"

"Who was the other?" Billie asked.

"Melinda Warren was invited and she attended through all her seven years and stayed there for a few years after." Leo answered.

"So this is obviously a big decision for you, Andi." Victor told the girl.

"Yeah, it is." She answered thinking.

"Well do you want to go?" Paige asked.

"Aunt Piper?"

"Sweetie, I maybe your guardian by legalities but Phoebe and Paige are too, and even by that we have always let you have the freedom to make your own decisions. If you want to go it is your choice and we will support you." Andi thought for another moment.

"Well, I think that this is a chance to learn about something other than what I have known my whole life. I would probably be crazy to try to give it up, I want to go. For at least a school year."

"Okay, you can go." Piper agreed.

(3 weeks later)

"Hi, Aunt Paige!" Andi greeted her favorite aunt as she opened the door. It had been a couple of weeks since Andi had gotten the letter. Today she and Paige where going shopping for her school supplies.

"Hi Andi, are you ready?" Paige asked.

"Yep!" Andi responded, today she was wearing a yellow dress with a brown woven belt at the middle, a blue short-sleeved denim jacket, and woven brown flats. In her hair she had a bright yellow head band with a daisy on the side, her necklace, and a yellow anklet on her right ankle.

"Okay let's go," Paige told her, she grabbed Andi's shoulder and orbed them to Diagon Alley. They appeared next to a shop and walked onto the street.

"Wow." Andi breathed astonished. She had never seen anything like this before.

"You said it." Paige agreed; she then began walking with Andi keeping up next to her. "Let's go open an account for you." The two walked into Gringott's bank. As they walked they looked at the goblins writing on paper.

"May I help you?" The bored looking goblin at the front desk asked.

"Yes, she needs money for school supplies." Paige answered.

"Does she have a vault?"

"No."

"Then she will have to open one, wait here while I get the paper work." Before the goblin could move a key appeared in front of Andi. She held out her hand and the key fell right into it.

"I thought you said she didn't have a vault." The shocked goblin finally spoke.

"She doesn't. There must be some mistake." Paige countered astonished.

"May I see the key please?" Andi handed the key to the goblin feeling a little nervous since she had never dealt with these kinds of goblins. The goblin examined it before calling another goblin over. The other goblin studied it then gave it back to Andi.

"There is no mistake. This young lady is the heir to the Warren vault."

"Aunt Paige?" Andi asked confused.

"I'm sorry the Warren vault?" Paige asked the goblin.

"Yes, you see that vault belonged to the greatest witch of her age, Melinda Warren. She was an auror for a few years before she moved back to America. But before she went back she put all of her remaining money into her vault and cast a spell on the key before giving it to us. She said that one day one of her descendants would come to Hogwarts and be the heir to the vault. When that happened the key would appear before them so that we would know exactly who it was. So the vault belongs to her."

"So would you like to make a withdrawal?" the first goblin asked. All Andi could do was only nod.

After withdrawing money from the enormous vault the duo went all around the alley getting supplies. After a while Paige checked the list.

"Okay, we still need your books, wand and pet, whichever one you picked." She read off. "I will go and get your books while you get the other stuff. Kay?"

"Okay." Andi answered. Paige gave her some of the money and split up. Andi set off for the wand shop called Ollivander's as she walked up the streets a boy about her age bumped into her and knocked her down.

"Watch where you're going." He snapped at her. Andi narrowed her eyes and quickly got up.

"Watch where I'm going?!" She shrieked. "You bumped into me!"

"I don't have time for this!" The boy growled and pushed past her.

"What, no apology?!" She called after him. She then rolled her eyes and walked forwards towards her destination.

"Whoa, looks like a tornado ripped through here." Andi commented as she entered. An elderly man came out the back and smiled at her.

"You're half right miss, and welcome to my shop, I am Ollivander. Now am I right to assume you are here for your first wand?" Andi smiled and nodded.

"Yes sir." Ollivander measured her with magical measuring tape and went in the back room quickly returning with a box. He opened it and pulled out a black wand.

"Here you are try this one." Andi took the wand and gave it a wave, the shelves suddenly were blown off.

"Sorry!" Andi apologized, Ollivander quickly took the wand back and went back to the back room. He came back with another box and handed Andi another wand. She took it and gave it a quick flick. A blast of wind nearly knocked her off her feet. She handed the wand back to Ollivander who thought for a moment before snapping his fingers. He went into the back room and returned with a box.

"Now let's try this one." Andi pulled a sleek brown and straight wand from the box that looked to be the perfect size for her. She gave it a wave and gold and silver sparkles shot out. Ollivander clapped.

"Wonderful, simply wonderful! Well there you go an 8" mahogany wand with a unicorn hair core. The perfect wand for you. Now that shall be five galleons." Andi walked over to the counter, handed over the money and took the wand case.

"Thank you sir, may I ask you something before I go?"

"Of course!" Ollivander said with a smile, "Anything for a polite young lady such as yourself. You are much more well-behaved most of the young children who come in here. Why, Draco Malfoy was in here a few minutes ago and was absolutely dreadful." Andi smiled.

"Thank you! Now, do you know where the pet shop is?"

"Of course the Menagerie is just a few doors up from here you can't miss it."

"Thank you, goodbye sir."

"Goodbye miss, and good luck at Hogwarts."

Andi quickly reached the shop and made a move to enter. But before she could someone bumped into her, she looked up to see a man who was taller than anyone of her uncles. He was carrying an owl cage with a snow-white owl.

"I-I-I'm so sorry sir." Andi stammered getting up. The man gave her a kind smile and she felt nothing but good waves from him.

"Don't be missy, it was an accident." He held out a giant hand, "Rhubeus Hagrid." Andi put her smaller hand in his to shake.

"Adrianne Halliwell."

"Wonderful to meet you, are you going to Hogwarts this year?" Andi smiled.

"Yep."

"Well then it looks like we shall be seeing each other again real soon. I am the groundskeeper at Hogwarts."

"Cool." Andi responded.

"Well nice meeting you, but I really should go and deliver this birthday present. See you at Hogwarts."

"All right nice meeting you too." Andi said and Hagrid hurried off. After he left Andi entered the shop. There where animals everywhere as she looked around in awe she saw one of the workers arguing with what looked like the owner.

"Shut it up!" The owner commanded, Andi sensed frustration from him and moved closer to listen in on the argument.

"I've tried!" the employee said who was leaking of desperation. "Blasted owl won't be quiet." Here he pointed to the owl cage.

"Well petrify it then. I won't have it scaring away all my customers." The owner finally said. As they discussed how to do it Andi approached the cage with the noisy owl. It was a beautiful owl in her opinion, it was small like her, black with grew specks on the back and wings. It stopped screeching when she reached the cage.

"You're not bad at all aren't you?" She asked reaching her fingers through the cage to stroke the owl. "You just want some freedom; I bet you've been stuck in this cage for ages. You don't deserve to be petrified, whatever that is, for wanting something so natural." As she spoke and petted the owl it hooted softly and leaned into her touch.

"Well, I'll be." Said a voice from behind Andi, she turned to find the store owner and the worker behind her looking amazed.

"We've tried for weeks to get that owl to quiet down and here you are doing it as if it was nothing." The employee commented. Andi shrugged at that.

"He just really needs a bit of love." The owner looked at her seriously.

"Tell you what; if you take that owl now with you, it won't cost you a thing. If you can keep him quiet you deserve him." Andi perked up.

"Deal." The assistant reached over and took a bag and handed it to her as she took the cage.

"And here is a bag of treats for you." Andi nodded and smiled.

"Thank you, good-bye." Andi left the shop and went to meet up with Paige, was waiting at the ice cream parlor and the two sat down for ice cream after orbing the rest of their purchases to the manor.

"I like your owl." Paige commented.

"Thanks." Andi replied.

"What's his name?"

"I think… Midnight, yeah Midnight sounds good." Andi finally answered after thinking for a few minutes. Paige nodded and the two finished their ice cream and orbed back to the manor.

Well you know what to do, review if you want to.
