Hey, how's it going? Just kidding, I'm not expecting a reply. You probably have something better to be doing. Anyways, this is going to be very AU. There's no god, goddess, demons, anything like that. In place of Mt. Olympus, we've got a super secret agency going on called Olympus 12 (I'm so creative, right?).

Anyways, this is just a fanfiction. I have no plans of making any profit off of this. Percy Jackson and the Olympians/Heroes of Olympus belongs to Rick Riordan, along with all of his original characters.

Artemis looked at her brother. Her brother with his golden blond hair, practically glowing. With his green V-neck shirt and khaki shorts. Girls were swooning all over him, and they still hadn't made it into the school yet. Artemis was simply thirteenth best compared to him because he took up the first twelve rankings. She was average, though kind of short for a sixteen year old. And she had terrible posture. She slouched all the time, making her look insecure and shorter than she really was.

"This is trash," Artemis muttered.

"What was that Arty?!" Apollo shouted over his ridiculously loud music.

"This is trash!"

"I thought it was a pretty accurate character description!"

"That's because you wrote it! I'm neither insecure nor short!" It was true. And she didn't slouch that much. It was barely noticeable now. Go back a few years and she would have had really bad posture. She was rather undeveloped, but she didn't care about that.

Honestly, she'd much rather have that than a bunch of idiot guys drooling all over her. This was the most ridiculous mission she had ever been sent on. And they just had to send her with her brother. Ever since the incident in Munich, Olympus 12 had been trying to keep her away from leaving headquarters.

You make one mistake and your career as an agent for a government-independent agency is practically destroyed. Now she was stuck going to high school, with her twin brother of all people. It was awful. She accidently got another Olympus 12 agent killed. She didn't expect the lizard to be so strong or for Zoe's father to kill his own daughter. But then, you could never count on anything anymore. But since it happened, Artemis Achristos was to blame. Artemis was there, so it was her fault. That's how Olympus 12 saw it.

"Don't blow our cover Arty."

"I won't." It was usually his fault that there cover was blown when they had to work together. He'd bed some girl, and he talked in his sleep… loudly. So the girl would typically ask what Olympus 12 was, and it would become Artemis's job to fix it all. Alter the girl's memories and make her forget about anything she might have heard about the agency. "Make sure you don't."

"Like I would. Come on." Apollo parked his car and got out. Automatically, girls were swooning over him. Artemis got out of the car and the comments changed immediately.

"Is that his girlfriend?"

"It's got to be his sister. There's no way she could be dating him."

"She's kind of cute in that drowned cat way."

School hadn't even started, and people already hated her because she got out of the car with her twin brother for school. People were just so infuriating. She hated them just as much as they hated her. When she was a full-fledged Olympus 12 agent, she had a squad all to herself. She was a prodigy, a genius. But Zoe died, so she was put on probation. It wasn't her fault.

Probation. It wasn't something she was supposed to be on. She was an officer. One mistake ruined everything she had been raised for. Fifteen and trained to kill, holding a "captain's" ranking. One year later, she was reduced to going to high school for a mission that her brother was in charge of. She didn't know what their objective was, for he decided not to tell her, saying that she didn't need to know yet.

Apollo had to check her schedule to see if they had any classes together. He seemed awfully excited for this whole experience of torturous exposure to a building full of annoying people their age, charged with hormones that made them ridiculously horny. Maybe because they would all be just like him, and then he wouldn't be the black sheep.

And then the stupid contraption on her locker wouldn't cooperate. 29-45-12. She had dealt with locks far more complex than this without even knowing the combination. Why couldn't she open a cheap locker made for an average teenager? This was pathetic.

"Want some help Arty?"

"No!" she snapped, not wanting Apollo to think that he was better at something than she was. But after seven minutes of complete failure, she relented and allowed her twin to unlock her locker for her. "Thanks."

"No problem, little sis."

"I'm older than you!" She went to close the locker now that she had put away what needed to be put away. It wouldn't close. She tried slamming it, but it just rebounded and hit her in the face. "What's wrong with it now?!"

"You accidently locked it while it was open." Somehow Apollo managed to sort out that fiasco. "Have fun in Chemistry, alright Arty?"

"Don't call me Arty."

"See ya during lunch."

She got lost heading to Chemistry. This map she had didn't match up with the actual layout of the school, and there weren't any labels on it anyways. How was she supposed to know where she was going if she couldn't read her map? This was ridiculous. Absolutely ridiculous.

"Are you the new student?" The old man was bald, had an awful lisp with a monotone voice at the same time. Artemis automatically knew that she wasn't going to even come close to experiencing a decent review of chemistry in this class.

"Yes sir."

"Would you like to introduce yourself to the class?" Introduce herself to the fools? That was juvenile. She shouldn't have to waste her time on introductions. She shouldn't have to waste her time here in high school.

"No sir."

"I'm sure they'd love to get to know you."

"I don't want them to know me." She knew she sounded like a child. Like she was the most immature being on the face of the planet. "But if I must, I must."

"Wonderful. Why don't you tell us all about yourself?" Artemis decided to be a smartass.

"My name is Artemis Achristos. I have a twin brother named Apollo. Our names aren't very creative. I never met my father, and my mother lives in Athens. I haven't seen her since I was two, and I have practically no recollection of my life in Greece. My surname Achristos translates to useless in English, and I find it to be the worst surname possible. I hate people, and most people hate me. I didn't want to attend high school, but I was forced to. My favorite color is silver. My favorite pastime is watching people suffer from afar. I find my brother to be annoying. I am a genius and could kill all of you in less than a minute if I found reason to. So you all are rather lucky I haven't found a legitimate reason yet. I am fond of the movie V for Vendetta. I hate fairytales. I have a record of hitting people that spontaneously begin singing songs from Frozen or other show tunes in general. In fact, I have yet to find any music I like. I hate poetry, particularly haikus."

"Miss Achristos, we don't-"

"I dislike meat pies, amputated body parts, and the thought of sexual intercourse. I am well learned in poisons, the method of decapitation, and how to avoid stupidity by attacking anyone who displays it." She went on and on, completely ignoring the teacher's pathetic attempts to interrupt her until he threatened to give her a detention. That was not something she would like to get on her first day of school. Even she had standards for something she hated to.

"You can sit behind Thalia."

"And that is?"

"Thalia, raise your hand please." No one raised their hand. No one looked inclined to raise their hand. And there were several empty seats, so Artemis couldn't just sit down in any one of them.

"That's Thalia," a student informed the short girl. Artemis nodded to acknowledge the black-haired boy that had pointed out Thalia. "And I'm Percy."

"Shut the fuck up Percy," the girl called Thalia snarled. Artemis really didn't like the position she was in, sitting behind Thalia and next to Percy. "She doesn't need to know everyone's name."

"That's Annabeth." He pointed at a blond girl, and then he pointed at a girl who looked like she had some sort of Native American background. "Over there's Piper."

"Very nice to meet you," Artemis said quickly. "But I think we should pay attention to the teacher."

"Fucking teacher doesn't even know what he's talking about." Thalia looked back at Artemis. "Yesterday he tried telling us that Na was iron. Anyone in AP Chemistry should know that Na is sodium, and iron is Fe, 'specially the teacher."

She was in AP Chemistry? With a guy that looked like he had no clue what was going on, a punk girl that's favorite word seemed to be fuck, a blonde that hadn't talked, and another girl that had smiled at her when Percy had tried introducing them? And the punk was saying that the teacher didn't know what he was teaching. What was this world coming to? Complete chaos, that's what.

Life was going to be a real nightmare.

The only good thing about high school was that Apollo couldn't bother her nonstop. He was in his classes and she was in hers. Artemis hadn't even seen him during lunch, but that might have been because Percy dragged her out into the courtyard so that she could meet a horde of teenagers that she shouldn't have minded meeting if she was a normal teenager.

There was Nico di Angelo and his older sister Bianca, who was suffering from sort of disease. Artemis wasn't really paying attention that much, though she felt bad for the girl. She was sick, and she had to deal with a brother that was kind of gloomy looking but was obsessed with some childish trading card game.

Piper McLean, the daughter of the famed Tristan McLean. They acted like Artemis should know who he was, so she pretended that she did. Piper was nice enough, kind of pretty. They had technically met in AP Chemistry, but Piper felt the need to re-introduce herself.

Annabeth Chase, an aspiring architect that had a debilitating fear of spiders. It seemed kind of pathetic, but Artemis kept her mouth closed.

Jason and Thalia. Thalia happened to be two years older than Jason but had been held back twice in elementary school due to her grades and terrible behavior. Jason however seemed to be the poster-child of good behavior with his neatly cut blond hair and nice casual clothes. Artemis noticed that he had a scar on his lip. And unlike Jason, Thalia had a mess of spiky black hair on top of her head, ripped black jeans and a Green Day shirt with the sleeves cut off.

Artemis wasn't sure what Green Day was, and she knew that she didn't want to ask Thalia what it was.

But other than that, school didn't seem too bad. Just classes full of material she already knew, silly homework that she had finished during class, and the boy, Percy Jackson, in all of her classes along with Thalia. And as the day went on, Artemis learned that Thalia was not as formidable as she had seemed during AP Chemistry. She was rather smart, but she also had a sense of humor. Fuck still seemed to be her favorite word though.

"Achristos," Thalia finally said in their English class. "D'ya speak Greek?"

"Yes." That was Artemis' quick, curt reply. She didn't want to get too far deep into a conversation. "Why?"

"You said you were from Greece, so I was wondering."

"Really? If I said I was a part of a secret society out on a secret mission would you believe me?" A mischievous grin had crossed Artemis' face. Of course, it was forced. She just wanted to see if her cover was strong enough.

"Nah, that's pretty hard to believe. You're just an immigrant whose mother did what was best for her kids." How nice. That was rather nice actually. Perhaps not all high school students were hormonal fools.

"You two in the back, Thalia and Artemis, you're going to have to be quiet if you want to stay in class." The English teacher obviously didn't know how to appreciate the bond between a trained liar and problem-child.
