Thanks so much for clicking on my story! I suddenly got inspired to write this, and I hope that this is unlike most of the high school AUs that you've read. To get this out of the way:

I do not own PJO, or any of the characters mentioned. They are all products of Rick Riordan's brain. Not mine. I only own the plot.

Before you go, here's a little grade guide (for those that will absolutely be in the story):

Freshmen: Nico
Sophomores: Hazel, Frank
Juniors: Annabeth, Piper, Jason, Percy, Leo, Rachel, Will Solace
Seniors: Thalia, Calypso
And Luke is a sophomore in college

Sorry for taking up so much time. Hope you like it!

Chapter One - Parties are a Pain

"I don't wanna go if you're not there," Annabeth whined to Thalia, loudly slamming her locker shut. "It'll just be a bunch of rowdy teenagers making noise."

Thalia's little brother, Jason Grace, was throwing a party at their house while their parents were on a second honeymoon in Greece. Well, it was less Jason and more his best friend Leo that was throwing the party, but putting Jason's name on the invitation ensured that plenty of people would show up.

Either way, Thalia wouldn't be there, so Annabeth saw no reason for her to be there either.

"You'll have Piper," Thalia informed her as they began to walk towards their lunch hangout area.

"She'll be running after Jason all night." Annabeth sighed, thinking of her friend's years-old crush on the Grace brother.

Thalia scoffed at Annabeth's comment. "Jason will be running around like a chicken with its head cut off, trying to keep the house tidy. If anything gets messed up, our dad will have a heart attack."

"Can't you just come? Please?"

"No can do, Anna," Thalia said, sitting down on the bench behind the staircase—their usual spot. "This weekend is the only time I'll be able to sleep over in Luke's dorm without my parents having a stroke, and I'm taking advantage of it."

Annabeth rolled her eyes, taking out her bag lunch. "You and your stupid college boyfriend."

"You'll change your tune once you get your own boyfriend."

"Yeah, on the fifth of never."

"You never know." Thalia smirked, her eyes twinkling mischievously. "At least go for Piper; she'll need someone to talk to."

"Ugh, fine. I'll go. But I won't enjoy it," Annabeth groaned, taking a bite out of her sandwich. "Where is Piper, anyway?"

"He's so cute, though," Piper sighed, staring at Jason as he talked to random party guests. Leo Valdez was by his side, tinkering with some little toy in his hands. He was speaking animatedly as well, somehow able to work with mechanics and speak simultaneously.

"He's also a little dumb," Annabeth responded, absentmindedly scrolling through Twitter on her phone. "How can he not see how much you like him?"

"He's not dumb!" Piper defended him. "He's just oblivious. It's not his fault."

"This is so boring," Annabeth changed the topic, ignoring Piper's comment. They'd had that argument too many times before, and they'd reached a stalemate that Annabeth didn't feel like dredging back up.

"Everyone else seems to be having a good time," Piper noted.

"Everyone else is drunk."

"Maybe you need to get drunk. Ooh!" Piper suddenly squeaked, causing Annabeth to jump.

"What?"

"Jason is alone. Sorry, Anna, but I've gotta take advantage of this. I'll see you in a little while!" Without waiting to see if Annabeth was okay with being left alone, Piper sprinted off to go and be with Jason.

"Why did I come here again?" Annabeth muttered to herself, just as she felt someone new occupy the space where Piper had just been. Annabeth looked over at the other side of the couch and saw that the new person was a boy with messy black hair.

Oh, it's Percy Jackson, Annabeth thought. Percy Jackson was the captain of the swim & dive team, as well as one of the school's resident troublemakers. He and his best friend Grover Underwood were notorious for causing mischief around Olympus High.

"Is this seat taken?" Percy asked, his sea green eyes twinkling.

"Well, you've already sat down," Annabeth replied sassily, looking back at her phone.

"Someone's got a mouth on her," Percy said easily, not even slightly put off by her answer.

"So I've been told." Annabeth looked over at him again, noticing how his smile lit up his entire face. "Where's your partner in crime?"

"Who, Grover?" Percy laughed. "You're a bit behind. He transferred to a boarding school at the end of last year."

"Seriously?"

"Yep. He goes to Pan Academy now."

"I'm sorry. That must suck."

Percy shrugged. "It does. I miss him, but he's happy there. He said he wanted to be closer to nature. And it doesn't hurt that his girlfriend, Juniper, goes to the nearby all-girl school, Nymph Prep." Percy had to stifle a laugh. "It's such an awful name for a school; it sounds like a rehab for sex addicts."

"I thought that it was playing on the nymphs from certain ancient mythologies. You know, the nature spirits like dryads and such. The spirits were always women, so it makes sense that they'd name an all-girl school that, especially if the school was founded a long time ago and has a focus on the environment."

Percy's eyes had glazed over at some point during her lecture, and he was watching her with his mouth hanging slightly open. "Wow," he said, snapping back to reality once he realized that she'd finished. "That's a really good point."

"Do you even know what I just said?"

"No," he admitted, and Annabeth laughed despite herself. She didn't understand why. She always hated it when people didn't listen to her. So how was it so endearing when this random boy did it?

"Forget I said anything," she said once she'd recovered from her little bout of laughter.

"No problem. You're really smart, huh?"

"I'm a certified genius," Annabeth informed him, her chest swelling with pride.

"Well, you outrank me. I sometimes forget where my house is."

Before she knew it, Annabeth was cracking up again. She had forgotten all of her earlier qualms about going to the party.

Percy looked over her shoulder quickly before meeting her gaze again. "Sorry, but I think that my friend wants me." He stood up from the couch, placing a gentle hand on her shoulder. "It was nice talking to you, Annabeth."

"You know my name?"

"Of course! You used to be class president; it'd be hard to not know your name. See you later."

He walked off, and Annabeth couldn't help but smile after him as she watched him walk towards a redheaded girl. But as soon as she turned back around, her smile melted off of her face. Piper was staring at her, a grin worthy of the Cheshire cat adorning her face.

"What's wrong with your face?"

"Nothing," Piper said quickly, trying and failing to stop smiling.

"I thought that you were going to talk to Jason."

That erased Piper's smile. Her face fell, her eyes drifting over to where Jason was now frantically trying to calm down some of the other party guests. "He's just so busy."

Piper was the school's resident matchmaker, and she had gotten several couples together over the course of her three years in high school. Everyone at school coveted her relationship advice, especially since she was super easy to talk to, and hardly ever judged people.

In spite of all of this, Piper was just as much of a hopeless romantic as anyone else when it came to her own love life.

"Maybe you should just get over him," Annabeth suggested.

"If I could, I would, but getting over someone is easier said than done."

"Well, he's always been this busy, and he's always going to be this busy, even if he's in a relationship. You should keep that in mind."

Piper pouted at Annabeth's annoyingly true comment. If Jason was often too busy to pay attention to her as a friend, how would he ever be able to give her the attention that she'd require as a girlfriend? Maybe she should just get over him.

Still, easier said than done.

Did I portray the characters well? Review to let me know how you felt!

See you later! I'll try to update as soon as possible!
