Author's Note: Hello everyone! This is my first crossover, (and second fanfiction) so please forgive me if I make a few mistakes. I am really happy to write this because 1. It contains my OTP (Percabeth!) and 2. I have always loved Hogwarts. Thank you for reading and I hope you enjoy it.

Chapter 1: The Boy with Black Hair

Annabeth's POV:

"What an idiot!" Annabeth exclaimed stomping down the hallway that led to the Ravenclaw common room. Penelope nodded her head in agreement while Padma and Pavarti chorused with sounds of sympathy.

"He spilled ink all over my favorite sweater! And he just laughed about it. He didn't even apologize," she grumbled. "That Percy Jackson has been on my nerves since last year when we met during the sorting hat ceremony. I was so glad when the hat put him in Gryffindor."

Penelope patted Annabeth's shoulder. "Don't worry Annabeth. A simple spell should help get that ink out. And Percy probably just likes you. Studies show that 78% of boys tend to try and annoy those who they are smitten with," she recited from memory.

Annabeth scoffed. "Percy doesn't like me. Have you seen him? He could get any girl he wants, many of which are much prettier than me. I mean, he's stupid, but he's not ugly. Besides, I have much higher standards. They include having an IQ higher than 20."

The girls all laughed at this, and arrived to the portrait that covered the entrance to the common room.

They answered the riddle that was given to them and stepped inside.

The Ravenclaw common room was filled with blue and bronze items, the colors of the house. It was almost empty, except for a few students that were studying in front of the fire. Padma and Pavarti headed towards the girl's dormitory while Penelope and Annabeth collapsed in to armchairs.

"Are you excited for classes tomorrow?" Penelope asked. Annabeth forgot all about Percy, and started talking eagerly with Penelope.

"Of course! I heard this year that we get to learn all new sorts of defense spells…" Annabeth began talking about charms class.

Percy's POV:

"… so annoying," Percy spewed to Ron and Harry. "Then she made it seem like it was all my fault. She's the one who ran into me, not the other way around. She's the one who needs to watch where they're going. It's like Annabeth solely exists to spite me."

Ron laughed. "I dunno, Percy. It seems like you kind of like Annabeth." Harry shrugged in agreement.

"Like her!? Please I despise her. She's such a know it all. She might be cute, but her personality has lengths to go before it even resembles something I would date," Percy retorted.

"Whatever Percy. Hey, are you trying out for Qudditch this year?" Ron asked. Percy started talking eagerly about sports with Ron.

Annabeth's POV:

The next day after classes Annabeth headed down to the lake with Luna. The early Fall air was crisp and cold, and the leaves on the trees were starting to turn color and fall off.

Annabeth had changed out of her wizard robes and was wearing a large red and white striped sweater with grey knit stockings tucked into her boots.

When Luna and Annabeth reached the lake the girls saw Percy along with Fred and George. They were trying to get the sea squid to appear by tossing large chunks of what looked like meat.

As Annabeth neared the water, Percy saw her and narrowed his eyes. He then proceeded to try and chase her with his meat-slime covered hands.

"That's disgusting, Percy!" she yelled at him, while he chased her along the shoreline. "If you get any of that on my clothes, I will put a curse on you. It took ages to get that ink out!"

Percy responded by laughing and saying, "Well you better run Annabeth, because I'm planning on getting this all over that pretty little outfit of yours."

Annabeth stopped abruptly, which caused Percy to charge straight passed her. He turned around, confused.

"Did you just call me pretty, Percy?" she asked slyly. He blushed crimson.

"Maybe I did, but I didn't mean anything by it, ok? You girls always overreact to everything," he quipped.

Annabeth's mouth fell open in offense. She whirled around and stalked over to Luna. "Let's go," she said. "These idiots have a giant squid to feed."

She huffed and marched back up the well worn path, Luna following closely in suit.

George and Fred looked back over at Percy. George started laughing.

"I don't think that's how you want to talk to a girl," Fred advised.

"Shut up," Percy muttered.

Annabeth picked at her dinner. She loved baked macaroni and cheese, but she was still upset about her confrontation with Percy. And even worse, he was starting to grow on her.

Sure he's an annoying jerk, but have you seen his eyes? Gorgeous. Not to mention his perfect hair, how it falls across his forehead in coal black waves… Annabeth snapped out of it. No. She couldn't fall prey to Percy's good looks. Too many other girls went down that path and it didn't end well for them. Besides, Percy wasn't that great, was he?

A week later, Annabeth was headed towards the library. She had spells to decipher, essays to write, and Percy to avoid. He had ignored her all week and Annabeth had safely assumed he disliked her as much as ever. But to be safe, she took the longer route to the library to keep her distance.

The library was filled with kids working and reading, but Annabeth finally found an empty table in the back of the library. She was well into her essay when she heard a book bag slam on the floor and the sound of someone collapsing in the chair across from her.

"Percy?" she asked in disbelief when she saw his face. "What are you doing at my table?"

He sighed in annoyance. "It's the only seat open, ok? If I was able to sit anywhere else, I would."

Annabeth's gaze narrowed. "Try the floor," she spit. But she moved aside some of her books so that he could use part of the desk. Percy took out a book and began whistling.

Annabeth tried to get back to her essay, which was due the next day. But Percy's whistling grew louder until Annabeth slammed her quill down.

"Could you shut up?" She screeched. Percy looked at her with his infamous half smirk, but didn't continue.

Annabeth started writing again, but soon Percy started drumming his fingers on the desk. Annabeth tried to block out the noise but finally she couldn't take it.

"I mean it!" She yelled, which received a glare and shushing from Madam Pince. "If you can't be quiet, just leave."

Percy leaned in close so that their noses were centimeters away. He smelled like mint and a touch of cologne, and Annabeth could feel her breath quicken.

"Am I annoying you?" he asked, each word rolling slowly out of his mouth. Annabeth's face grew red, but she managed to keep her composure.

"Yes," she said, her voice quavering. Percy leaned back into his chair, the smirk back on his face.

Normally, the smirk would have annoyed her so much that Annabeth would have liked to slap it off his face, but now, she seemed to almost like it. No, no, no, this would not do. She could not start liking Percy.

Her problem was solved for the moment because Percy picked up his book bag and walked out of the library. Annabeth let out a breath she didn't know she was holding.

Percy's POV:

Percy speed walked away from the library. How could Annabeth not see how red his face was?

He had done everything he could to try and study, but Annabeth was so damn distracting, so he couldn't focus. The way the candle's reflected off of her perfect hair. And how she stuck out her tongue when she was thinking was so cute. Percy had to get out of there. If Annabeth found out he liked her… oh man, he better not think about that.

But wow was she cute.

Thank You for reading. I didn't like that chapter very much, but I had to start somewhere. Thank you again, and please review!
