A/N: Alrightio. So, I'm not sure where the tumblr post is or even really who started this AU, but I got inspired to write Annabeth and Reyna being swapped instead of Jason and Percy by a tumblr post a while back. It's taken me a while to get it to the point where I felt I knew both characters enough to narrate with them, and it took a lot of guts to try this, but I hope this does not disappoint. This is a massive undertaking, the way I've designed it, as I'm essentially rewriting the entire series, but I'm actually really excited. But, since this will be a big commitment, I'm going to ask you, my readers, something I've never asked before: if you like this story (or any of mine, really, if you'd like, but mostly this one) please tell people about it. If only ten people respond, I might not be able to make time to write it, as I am a junior in college about to start student teaching next semester, so I've got a lot on my plate. However, if people like this story, I am willing to, metaphorically, squash some things out of the way to make for a nice, big serving of Reynabeth Swap. So if you like this, tell your friends! And if you like this, review! Let me know what you like, what you don't, and I will do my best to keep this going if there is a demand.

Tl;dr, tell people and me if you like it!

Love you all and I hope I do this story, AU, characters, plotline, and the fans the honor they all deserve,

Sara

She was woken up by someone muttering nonsense and wrapping their arms around her waist. It took a moment – where was she?

Wait a second.

WHO was she?

She breathed deeply. Okay, that's a bra, accompanied by boobs. And those are underpants, not boxers accompanied with boy parts. She was definitely a girl. Yep, long hair. A girl. Well, female. Likely a girl.

Another deep breath. Her name. She had a name. Of course she had a name. And, gods be damned, she would make one up if she didn't. Wait. Gods? Whatever.

R-Rachel? Ray – Reyna! That was her name. She was Reyna.

Reyna blinked, slightly disoriented, and sat up. "Wh-what's going on?" she said. A slight, strangely yet astonishingly pretty brunette girl was half asleep in her lap. As if instinct, Reyna reached her hand down to brush some of the hair out of the girl's eyes. She sighed contentedly, snuggling in closer to Reyna, who suddenly began to realize how strange this whole situation was. Yes, a girl in her lap when she didn't know her own name. Something was missing here.

"Aw," said a kid in the seat in front of Reyna, looking over at the two of them. "You two are canoodling. Again." He frowned. "I know you two are dating and all but don't I get a cuddle every once in a while? Or a hug?" He exaggerated the frown. "You know, you guys used to like me."

"Excuse me?" Reyna asked. "I'm…" Reyna paused. It took her thirty seconds to remember her name. It took her thirty seconds to even be sure she was female, for gods' sake. It was stupid to assume she wasn't dating this girl. "What?"

The kid frowned. "You okay, Rey? You seem," he studied her face, "perplexed."

The girl in Reyna's lap fidgeted and sat up, rubbing bleary nap-blinded eyes with her fists. "Oh, don't mind me," she grumbled, "just trying to nap on my girlfriend here, I hope I'm not interrupting your babbling, Leo."

The boy, apparently called Leo, shot a grin over toward her. "You don't need that beauty sleep, Pipes, you've got it all anyway." He glanced over at Reyna. "This is the part where you usually tell the two of us to knock it off." He stared at her. She stared back.

"Dude, what's wrong with her, Piper?" Leo asked the girl in Reyna's lap. "Did you break her or something?"

Piper brushed her hair out of her face and shook her head. "She was fine about twenty minutes ago. She said she was tired, I mentioned that Coach wouldn't be able to yell at us for falling asleep, because, hello, like he could see over the seats, and we conked out."

"Coach?"

Piper nodded up to the front of the bus, and Reyna adjusted herself from the slouch to peer over the back of Leo's seat. "That's Coach Hedge," said Leo, "he –"

"Valdez!" barked the extremely short man in front of them, "shut up before I make you shut up! You kids back there don't want to volunteer for bus cleanup, do you?"

The three shook their heads. Reyna might barely remember her name, but she damned sure knew that the last thing she wanted to do was cleanup.

They slunk behind the seat again. "Piper, is he allowed to talk to us that way?" asked Reyna, feeling indignant. No one spoke to her that way, she thought with conviction. Why, of course, she felt like speaking that way to her was different to another was something she couldn't answer at that particular time.

Piper nodded. "The kids are the animals here." Piper turned to her, smiling, but Reyna had a strange feeling there was a joke she was missing, a smile from the past she was forgetting.

Reyna felt herself struggle to remember, struggle to think about something from her past. But nothing was there. "I don't think I'm supposed to be here," mumbled Reyna.

Piper looked like she had been punched. "I – don't let Isabel and them get to you," Piper said, her voice low but fierce. "I don't care what they've been saying about us. You're –" Piper paused. "I don't care that they call me horrible things. I don't care what they say." She took Reyna's hands, bewildering her. "And – and I don't think you should either."

Reyna was startled – people had been homophobic toward the two of them? Hell, Reyna didn't even know her last name, let alone her sexuality. And she definitely didn't remember bullying. This memory issue was becoming more and more complex as the seconds went by. Besides, the thought of anyone being rude to herself or Piper as borderline rage inducing.

"It's not that," said Reyna, "I really don't think I'm – I don't feel like I'm literally, actually supposed to be here on this bus."

Piper blinked and dropped Reyna's hands. "Oh," she said, "well, I, um, I guess that's…" She reached over the bus seat and, Reyna assumed, hit Leo over the head, because next thing Reyna knew, Leo was peering over the seat with a slightly displeased glare. "Don't hit me," he said, frowning, "it hurts my soul. And what?"

"There's something wrong with Reyna," said Piper, wringing her wrists and not meeting Leo's nor Reyna's eyes. "She – she doesn't remember. And I don't think," Piper looked up, looking into Reyna's eyes finally. "No. She doesn't know who I am."

"She knows you're Piper," said Leo, turning to stare at Reyna like the answer was written across her skin. "She definitely knows." He furrowed his brow. "You know she's Piper, right?"

Reyna, reluctantly, shook her head. "I know she's Piper," she began carefully, "but I don't know who Piper is. And I don't know who I am."

"You're Reyna!" said Leo with a grin, but it was clearly forced. "You love me and put up with all my stupidity. I put Jell-o in your pillow one night, and you responded by shoving the Jell-o and half of your pillowcase in my mouth." He sighed like it was a treasured memory. Reyna was sure she had to be insane to have him as a friend. "We're best friends," continued Leo, "You give me your deserts. And you clean my –"

"Leo," cautioned Piper.

He shrugged. "Well, we are your friends. Well, I am. Piper, on the other hand –"

Piper blushed. "Look, if she doesn't remember, we can't force her or anything. I just," Piper sighed. "I thought you were done with- with us and didn't want us to be…" Her sentence trailed off. "Never mind. That's not the important part right now. What questions do you have?" Piper frowned, which looked quizzical and adorable on her, as opposed to Leo, who looked as if he were struggling to breathe and needed help.

"Let's start off with where we are and why we're on a bus with a very small man who looks as if he wants to kill us all."

"We're students at the Wilderness School," said Piper. "It's not fun. Or pleasant. Or – useful, really. Everyone here is some sort of trouble maker."

Reyna blinked. For some reason, troublemaker didn't seem like the right thing for her. Weirdly enough, she felt more like she would make the rules than break them. "What did you guys do?" she asked.

"I'm a runaway," said Leo with a shrug. "And Piper, innocent as she looks, stole a car."

"I didn't!" exclaimed Piper.

"Sure, right, he gave it to you," Leo shot Reyna a look that clearly meant can you believe her? But, somehow, Reyna almost did. And she almost believed that she and Piper were together. And she almost believed that there was something about this place that felt familiar. Or someone.

But she wasn't sure of anything but the fact that she wasn't supposed to be there.

"I still don't think this is right," Reyna mumbled. "Something's wrong."

Piper sighed. "Well, we'll figure it out, okay?" She smiled at Reyna with something so pained behind it that Reyna almost knew that that kind of smile would only be cured with a kiss.

Where was this COMING from?!

"Cow goes moo!" called someone from the front of the bus.

"What on earth…?"

Leo snickered and pulled out a screwdriver. "I've got some highly marketable skills," he said with a wink. "I'm a special boy."

Piper laughed. "That's truer than anything should be."

The three of them walked out of the bus and made it halfway to the building before some girl yelled, "Hey, lesbo freak, got any relatives drinking up a storm on this property?" She smirked. "Because they'll probably kick you out now."

Reyna's jaw dropped. Did this girl SERIOUSLY just say that?

Piper, to Reyna's shock, just scoffed. "First of all, just because I'm dating a girl doesn't mean I'm a lesbian. Second of all, if you had any brain at all, Isabel, you'd know I'm Cherokee and this reservation is Hualapai. Of course, you'd need to think to understand the difference, so I can't exactly expect that from you."

Leo and Reyna snickered. Reyna had a feeling that, yep, this was why Reyna-with-a-memory was dating Piper.

"Oh, so you're not a lesbian?" replied Isabel, looking a little off kilter but still fighting for a breaking word. "So you're just playing gay pretend?"

"Even if she was 'pretending,' which she's not, that's better than pretending you're better than people because your rich mom and daddy don't care enough to take you home for the holidays," said Reyna before she really realized what she was saying. It was a guess, what she had said, but it really hit home.

Isabel swayed like Reyna had punched her. "I – they're at Sandals!" she exclaimed. "It's a couples resort!"

Piper rolled her eyes at Reyna as Isabel walked away.

"You don't have to do that," said Piper under her breath. "I can fight my own battles."

Reyna would have responded, but then Coach Hedge called, "The horse says NEIGH – I mean, stick with your partners!"

"Partners?" asked Reyna.

Leo nodded. "You're with me, and Piper's with –"

"Hey, babe," said a blonde guy with a disgustingly white smile. "You excited to be my partner?"

Piper glared at him. "If excited means I've never been more tempted to stab myself with Leo's screwdriver, than yes indeed."

Dylan laughed as if Piper weren't being horribly serious. "You're so cute, Pipes. I think that's got to be the whole attraction to me thing talking."

"Something that doesn't exist can't talk," Piper deadpanned. "And don't call me Pipes." Unfortunately, though, she couldn't move his arm and walked with her in the opposite direction.

"Should I have not said anything when that girl was taunting her?" Reyna asked.

Leo nodded. "That kind of was the thing that clinched it for me."

"Clinched what?"

"You'd never jump in for her battles if your memory was here, if you really knew what was going on – Piper's good with words. She's always the one to jump back with an insult."

Reyna nodded slowly.

When Leo went over to the bridge to look at some types of rock, Reyna was cough off guard but a hand on her shoulder.

"Alright," said Coach Hedge as he spun her around, "who are you?"

"What?"

"Are you that special package?" Hedge asked. "Because I'm supposed to be expecting some sort of special package that's going to be picked up later, and you're new, so I'm guessing it's you."

Reyna honestly couldn't come up with anything better to say than, "What?"

Hedge sighed. "Look, I'll figure this out. I'm assuming it's you, because you ended up with the other two demigods, so it's got to be you. Hopefully we get this figured out before –"

There was a crackle of lightning and a gust of wind so hard that it nearly made Hedge topple over his feet. "I had to say it," he grumbled."

The storm started abruptly, before Reyna could even blink. By the time she thought to help, Piper and Dylan were already herding the other students into the building, Piper and her coat nearly blowing away in the freezing air, but looking calm and collected.

That's when all hell broke loose.

"Good times, Piper," said Dylan, laugh like a tornado shredding a rooftop. "But these good times are going to end for you now."

"The what are going to who now?" said Piper, looking baffled.

Dylan smiled broadly and began to swirl, becoming something that Reyna recognized. "Ventus," Reyna said quietly. "You're a ventus."

Dylan whirled around to stare at her, even though he couldn't possibly have heard her with human ears. "How do you…?" He grinned. "Oh, I know who you are."

"Then why don't you tell me," said Reyna, striding toward him. "How do you know me?"

Dylan grinned, "Monsters know things, little demigod."

Dylan gestured downward, and air began to swirl on either side, two new venti forming next to him.

"Don't you come near any of my little cupcakes!" screamed Coach Hedge.

And suddenly, his pants were off and little goat legs appeared and Reyna thought she must have inhaled some sort of fume being excreted by the canyon because, hello, a student became a Roman storm spirit and a Coach became half goat. This was ridiculous. She had to be tripping or something. "Faun!" she shouted. "You're a faun!"

"Satyr!" he replied, looking offended. "I'm a satyr! Fauns are Roman!"

Not having any idea what that meant, Reyna decided the best option was to dart out of the way and hope something that she'd get an explanation within the next few seconds.

She didn't.

Coach Hedge made his way to the venti that used to be Dylan, pulling out a club from Reyna wasn't sure where. "Come here, you little monster!" he yelled. His club swung and passed through it like nothing, and the venti sucked him up and spat him out onto the ground. "I knew there was a reason I hated you!" he shouted, though muffled from the winds.

Piper and Reyna's eyes met, and in an instant Reyna created a distraction and Piper ran for the club.

"Pick on someone your own size!" shouted Reyna. "Yeah, that's right! Come and get me!" The ventus glared at her, moving toward her, until Piper appeared behind it, grinned at Reyna, and smashed it on the head until it collapsed.

That girl was, cute, smart, and violent – Reyna decided that, even if perhaps she wasn't actually dating Piper, she might want to consider making that a possibility.

While Piper was incapacitating the first ventus and Reyna was searching for the second, the third ventus attacked Piper, slamming into her and sucking her up into the strangest whirlwind Reyna had ever seen. Another ventus came out of nowhere and sucked Leo up, throwing him over the cliff. "HELP ME!" he shouted.

"Hedge, you get him!" exclaimed Reyna. "I've got Piper."

Hedge nodded at her, which was slightly confusing because, hello, when did she start giving the orders, but Reyna wasn't too worried about that yet.

"What the – Dylan! What in god's name are you doing?" Piper was doing some sort of dance, and Reyna thought for a moment and realized it looked strangely like a jazz square. "Get me out of him!" shrieked Piper, flailing still. "I don't care how weird that sounds, just – help!"

Reyna looked back and forth. Coach Hedge, the faun, no wait, satyr, was still trying to find Leo, the rest of the students were trapped inside the museum, and Piper, of course, was incapacitated.

Steadying herself, Reyna prepared herself and sprinted toward the venti. Instead of it disappearing with Piper, it was so startled that it simply let Reyna plow right through it, into Piper, and the two girls soared through the air briefly until they hit the ground.

Piper groaned.

"Sorry about that," said Reyna with a cough, "didn't mean for it to go – that way."

"Nope, no problem, really. But thanks for saving my life."

The two stared at each other for a moment. Though Reyna's were dark, black to the point where her pupils often meshed with her iris, Piper's eyes were so many colors Reyna could have spent hours counting them and only managed half.

Reyna realized she had been staring only after Piper broke eye contact and coughed a bit.

"Ack," mumbled Piper, tapping Reyna on the shoulder. "Kind of lying on top of me, Rey, mind getting up? I'm having trouble breathing."

Coughing awkwardly herself, Reyna rolled off of Piper and stood.

"Where – where are Leo and the satyr…Coach Hedge…Goat…thing?" asked Piper, brushing herself off.

"Not sure."

They were answered in moments when Leo came flying over the edge of the cliff, with Coach coming up behind him. Leo groaned. "Couldn't have been more gentle, goat boy?" he complained.

"Excuse me!" said Coach, holding his club tightly and his eyes locked on the venti regrouping in front of them. "I just saved your life, small boy. You call me goat boy one more time and I'm going to tell people about that time you got locked in the bathroom and fell into the toilet!"

"HEY!"

Reyna and Piper, despite the situation, both began laughing. Unfortunately, this triggered the attention of the venti.

"Oh, gods, you people are so dumb!" shouted the former Dylan. It launched itself at Reyna, but she dived out of the way in a moment, landing in a roll and nearly flying off the edge of the canyon. Piper dived in the opposite direction, rolling into the wall of the museum, and falling still when she hit her head hard.

With Piper out of commission, and Reyna halfway to falling off of the cliff, the venti was attacking Leo now.

Scrambling for purchase on the unstable ground, Reyna threw her legs onto the dirt and used the momentum to roll the right way, landing in a crouching position. "Move out of the way, Leo!" shouted Reyna. She allowed herself a brief look over to Piper who, still dazed, was now stirring. "Hedge, Piper!" The satyr nodded and took off for Piper, while Reyna looked around for some sort of weapon. She found nothing. "Oh, hellfire," she cursed.

While the venti was still paying attention to Leo, Reyna bolted over, and, without really thinking about what she was doing, slammed right into the venti before it could tell that she had hit it.

"Yo, girl," said the former Dylan, "is is not how the two of us were supposed to do this!"

"Yo, jackass," growled Reyna, reaching instinctively for her pocket and drawing out a dark green hair clip and flicking it open. It grew shockingly until she was holding a massive sword in her hand, and pressed it against Dylan's throat. "Still want to hit on me," she said, "again?"

Dylan froze in front of her until she pressed the sword even harder into his throat.

Dylan laughed, frozen and wispy like the worst of a windstorm. "You think a mere sword can scare me, daughter of war?"

The spirit disappeared, leading Reyna to drop to the ground on her stomach and land hard. She groaned. "Oh, mother of –"

And daughter of war? Was she really that violent?

She paused. Of course she was. She almost killed him with a sword that had been a hair clip the last time she'd really looked at it.

She stood and ran to Piper, with the sword in her hand, bending it slightly and being not surprised enough when it clicked into being a hair clip again. Piper was being cradled in Hedge's arms. The satyr looked up at Reyna. "She's not – well, she's not out, but she's not really sentient yet."

"Then what do we…?"

"Leave it to me!" shouted Hedge. He launched himself over to the venti, and, before Reyna could make even a single move, they swept him up in a furious cloud, and disappeared.

Leo stumbled over. "What the sweet hell just happened?" asked Leo.

Reyna shook her head, shifting Piper so that the other girl was supported in Reyna's lap. "I have no idea at all."

Leo looked down at Piper, who was still unresponsive. "Is she – is she okay?"

"Applesauce," said Piper, smiling a bit, "Dad likes applesauce. Got it for me when I was sick and he was home between shoots." She sighed, and dropped her head onto Reyna's shoulder as if she wasn't quite sure what she was doing or where she was. "Applesauce."

"This is not good."

Leo looked around for a moment, and pulled out a water bottle from his back pocket. "Here, give her some of this."

"Where did you get that?" Reyna asked suspiciously.

Leo shrugged. "You go on the run, you pick up some habits. Like snagging things that might become handy in situations." He frowned. "Usually, though, those situations don't involve killer wind." He paused. "That came out way wrong."

Piper and Reyna both managed a laugh, which surprised Reyna. "You're okay?" she asked Piper.

Piper nodded and sat up slowly. "Yeah – I, I'm fine. Just a bit dizzy."

"Drink this," said Reyna, holding the bottle up to Piper's mouth.

For a few moments there was silence as Piper drank, the three of them staring at the ground as they tried to process the day.

And then the silence was broken when a chariot began falling from the sky, clearly aiming to land in front of the three of them.

"Am I the only one who's confused?" asked Leo, looking between Reyna and Piper. "Or is that actually a badly driven chariot with two flying ponies as pilots."

"Nope," said Piper, eyes locked on the disaster unfolding in front of them. "Nope, I'm confused too."
