A.N So this is just a story I wanted to write. I really don't know how to clarify it. There's Percabeth, Leo/OC, and Jason/OC (Sorry Jasper fans) but it's mostly telling Lyric and Percy's story. Enjoy and Review!

Finding your sister.

Chapter 1: Going Under, Finding out

(A little after the Giant War)

Lyric

"Are you sure you don't want to go?"

"Positive, I don't really like the beach." My best friend, Emily said as we walked down the hall.

I stopped cold. "How do you not like the beach? It's like not liking puppies." I turned to her "Impossible."

"It's very possible to not like it." She laughed when I shook my head in disagreement.

"How so?"

"Maybe it's the sunburn… or the sand in places where it shouldn't be… or the fact that last time I went with you, I thought you died."

"I wasn't under that long."

"It was 10 minutes! I thought you drowned yourself."

"I didn't know I was out that long. I just like it underwater. The world seems less real."

"Whatever. Are you coming to the swim meet?" she asked.

"Can't. Horseback riding."

"Did you tell coach?"

"Yea, I told Hedge." I saw one of my other friends down the hall. "I'll catch you later, Emmy."

"Later, Pandore."

"Hey Grover." I said to the scrawny boy putting books into his locker. "Do you need help?" Grover had this Muscular Disorder or something, making him wear crutches for all his life.

"I'm fine, Lyric. Thanks for asking." He said in a quiet voice.

"So, are you coming to my competition on Saturday? It'll mean a lot if you came."

"Sure, I'll come." He smiled sheepishly. "I'll catch up with you later."

"Alright. Don't forget, it starts at one." I called after him.

I should probably explain who I am before I continue.

But I don't really know who I am.

I guess I'll start with the basics.

My name is Lyric Pandore. Some call me Pandore or Pancake or Sea Lion. But whatever you want to call me is fine. I've lived in San Diego all my life, Crystal Pier to be exact. My mom's an Oceanographer and Dad…

Well, Dad's a tricky story.

I never knew my dad. I think I remember little things about him. But mom said she was still pregnant when he died. She never really went into depth about it. Just said one day he went off sailing and never came back. You could tell it took a real chunk out of her heart because the way she talked about him and how he was her biggest inspiration to be an Oceanographer. She talked about how I may have looked like her but I had his eyes, and how if he saw me now he'd be proud.

What was there to be proud of? I had fairly decent grades. (A kid with ADHD and dyslexia can only get so far). I tried to make up for them by being involved. I cleaned up lakes every year, I'm captain of the swim team, and I even raise horses. But those were things I was just good at and they didn't really help with getting a job or into college. I'm not really sure I want to go to college.

Like I said, I'm not really sure who I am.

Percy

"Grover!" I said excitedly. It was rare when Annabeth and I got an IM from him. "How's the assignment?"

"It's okay. But I think I have some news you won't like."

"That is?"

"Well, remember how I got sent out here to protect one Half-Blood?"

"Yea?"

"Well, I may have found two."

"That's great!" Annabeth said.

"That's not all…"

"Well, what else is there?" I asked.

"I think she's your sister."

"I don't have a sister. I mean, Dad would've told me if I did, right?" I looked to Annabeth for reassurance. "Right?"

"Well…"

"You can't be serious."

"Well, he didn't tell you about Tyson."

"That's different."

"How so?"

"For one, Tyson's not a Half-blood, he's a Cyclopes." I said. "And after the Titan War he told me I didn't have any siblings."

"Did he say that specifically?"

"…No." I said warily.

"But how did she stay hidden so long?" Annabeth said, confused.

"Her mom's like Percy's, she's smart. Children of Poseidon are usually found because they have a natural smell of the sea. Lyric's lived on the beach all her life so monsters couldn't find her."

"What about the other half-blood?"

"Emily, I'm pretty sure she's a Hephaestus kid."

"How so?"

"President of TSA. Won 19 inventor's awards. 6.0 GPA, because of all the A.P technology classes."

"Oh. Well, when are you and Hedge bringing them to camp?"

"Saturday, after Lyric's competition."

"How are you going to get here? I mean, you have a Child of Poseidon, you can't fly."

"Haven't really thought of that." Grover squeaked.

"I'll bring them." I spoke up. Grover and Annabeth looked at me, shocked. "I'll bring Mrs. O'Leary. And make sure they get here safely."

"Grover? Are you ok?" I heard from the background. "That's Lyric. I have to go." He waved before swiping his hand across the image. I stared at where the image had been until Annabeth grabbed my hand.

"What're thinking about?" She asked me. I sighed.

"Why wouldn't dad tell me? I think I'm more upset about the fact he didn't claim her, even after both wars."

"So, what're you going to do?"

"I—I guess I don't know." I sighed.

"Hey Grover!" I said, walking through the crowd of people. He was standing with a girl with straw blonde hair and glasses. She had on a trust me, I'm a nerd shirt, with a pair of shorts and she was talking into a Bluetooth.

"Percy, this is Emily. Emily, Percy." I waved when she looked up. She turned a bright red, and laughed really nervously, and turned away and continued to talk in her Bluetooth.

"Emily's… shy." Grover explained. "Like around guys."

"Oh." I said. "So, where's Lyric?" Grover pointed in the direction of the stage.

On the stage was a girl wearing a pair of black swimming shorts and a pink bikini top. She was talking to a really muscular guy, who looked intimidated by her. She had long Raven hair with a turquoise streak, and gigantic sea green eyes. She turned to the side and right above her hip was a tattoo "Natus ex mare"

"Born of the sea." I translated quietly. "Does she know?" I asked Grover.

"No. She just likes Latin and the beach." He said. "I think when she finds out she'll be more happy then shocked."

"Lyric, Are you ready?" I heard Emily say into the Bluetooth. I looked onto the stage and saw Lyric talk into the starfish shaped hairclip. Emily pressed a button on the remote she was holding; Lyric's surfboard began to glow.

"Are you guys cheating?" I whispered Emily, who began hyperventilating.

"Perce, take a step back." Grover laughed. Emily blushed to her neck.

"We're not cheating, it's a safety precaution. Lyric doesn't know how to take it easy. So I put a magnet in her surfboard and her surf shoes so when they repeal, the polarity of the water won't let her drown." Emily said a little too fast.

"Huh?" was all I could say. Emily just snorted. I turned back to the stage but Lyric wasn't on it. She was on the water.

Going downward on a 10-foot wave.

She kept going down and down and down until…

She was underwater.

I heard Emily yelling something like "you said you'll be careful" in the Bluetooth. I watch as the wave rose and Lyric was still under. Then I saw a shape shoot out of the water. I focused on it until I realized it was Lyric she began to surf toward the shore on the wave as it began to crash. She was walking on the shore by the time the wave crashed. The crowd began to chant "Sea lion! Sea Lion!" As they handed her a trophy which she held in the air.

Lyric began to jog toward us as the crowd began to break apart. She held the massive 1st place trophy in her hand as she jogged to us.

"Hey guys!" she said smiling. "Who's this?" she said pointing at me. Grover was about to introduce me but was interrupted by Emily.

"You bitch!" she said punching Lyric in the arm. "You said you wouldn't do that again!"

Lyric sucked in a breath. "I lied?"

"Yea, no kidding!" Emily said punching her several more times.

"I got 500 dollars out of it though." She smiled "I'll buy you Starbucks."

Emily smiled. "Fine. But I'm still mad at you. You could've died."

"I wouldn't have died. I wouldn't have done it if I didn't know what I was doing."

"You're arrogant."

"I'm not arrogant, I just have a false sense of self-esteem." Lyric laughed. "So, who is this—"

We were interrupted by a crash and Emily fell to the floor with an "Oomph." She was hit with the butt of a sword. Holding that sword was a gorgon. I pulled out riptide and annihilated the monster at once. Lyric looked at me, shocked, her unconscious friend in her lap.

"Who are you?"

I held out my hand. "Percy, Percy Jackson."

Emily

I woke up to someone shoving what I thought was pudding in my mouth, though it tasted like potato chips. I looked up to see a blonde boy with soft blue eyes. He was hot.

Cue hyperventilation.

I tried to lean up but he stopped me. "Take it easy, you have a concussion. So, what's your name?"

I blinked at him, and then gulped.

"Don't expect a word out of her. She can't really talk to guys. Some insecurity complex." Lyric said walking in.

"Over-active Insecurity Complex." I said sheepishly. "I overthink everything and what I'd do if I say the wrong thing and then I end up saying nothing and hyperventilating."

"You should talk to the Aphrodite girls. They could help you break out of your shell." The Blonde boy, whose name was Will smiled.

"The who?"

"Oh, apparently we're Demigods." Lyric said excitedly.

"I'm not. I have a mom and my dad's dead." I said confused.

"Honey, your mom lied." Lyric said, semi-sympathetic.

"Ok, ok. This is a lot to process. So Greek gods are real?"

"Yes." Will answered.

"And they still have Children with humans?"

"Yup."

"And that's what I am?"

"Basically."

"Then who's my dad?"

"Well, you got claimed while you were unconscious. You're a Child of Hephaestus."

"Isn't that an STD?"

"Em, that's Hepatitis." Lyric laughed. "Hephaestus is the god of the Forges. You know, Blacksmiths, inventors, Pyromaniacs." Will snickered at her comment and I saw her wink.

"Ok, am I free to go?" I asked.

"Whenever you want to. Lyric, can show you to your Cabin."

"Lyric, if we're demigods then who's your dad?"

Lyric turned smug. "I wouldn't know. Undetermined." She said pointing to herself.

We walked around the camp for a while. Lyric showed me the things they showed her but it seemed everywhere we turned someone was whispering. Lyric grumbled.

"Why're they whispering?" I asked her.

"Just a petty rumor. Saying I'm a big three kid, whatever the fuck that means."

We stopped in front of a cabin that looked a little bit like a metal shop. The bronze colored 9, hung over the door.

"This is so cool!" I said, touching the etchings on the outside of the cabin.

"Coolest cabin in camp." I heard a voice come from the inside. "But that's because I'm the counselor. Leo Valdez." He said, holding out his hand.

"Emily Lanchester." I shook it happily. "And this is my friend, Lyric." I heard her stifle a gasp and her cheeks inflamed.

"Hi." She finally managed to squeak out. He smiled at her and she started to hyperventilate.

"Well, Emily. I'll introduce you to the others when you want to come inside." He said before walking back inside. I turned to Lyric and opened my mouth to say something.

"Don't you dare." She held up a finger.

"This is just the first time I ever saw you freeze up around a guy, it's like we switched roles." I said, then I gasped. "Oh my god, you like my brother."

"Shut up."

"Oh, Lyric. That's so cute—"

"Em, I'll kill you."

"If you do I'll scream it."

"No you wouldn't—"

"LYRIC LIKES—"

"SHUT UP!" She yelled before storming off.

"I love you!" I called after her.

"I'll murder everything you love." She responded.

Lyric

So apparently I'm a demigod.

Yay.

I would be more excited if I wasn't wandering like a stray puppy no one want's.

Today was a weird day. First I get attacked by snake ladies then I find out not only is Grover half-goat but so is my swim coach.

So here I was, sitting down in the middle of the camp on the grass. When a something started blocking the sun. I opened my eyes and saw someone standing over me.

"Ugh." I groaned.

"Get up, Punk." She said, venomously.

"Yea, I don't think so." I said adding equal amount of venom.

"Who does this girl think she is?" The girl said to her friends who laughed in agreement.

"Look, I'm already having a bad day and I don't need a bunch of steroid taking Barbies making it worse." I say. Next thing I know, I'm being yanked up by my hair.

"Someone's got to teach you manners." She said. People are already gathering around us, until I hear.

"Let her go, Clarisse." I look up to see it was Percy who said it. Standing next to him, was a blonde girl with startling gray eyes.

"No. someone's got to teach the newbie how to talk to people around her—" She was cut off by me, landing a perfect roundhouse kick to the side of her face. She let go of me and stumbled, then pulled what looked like an electric spear out. She tried to land a blow on me but I ducked and sent a kick to her feet causing her to fall over. By then the whole camp was crowding around the dispute. Chiron was running toward us. I grabbed the spear and pointed it at her jaw.

"Don't move." I said when she tried to get up.

"Lyric?" I heard Emily whisper.

"What?" I said, irritated. She pointed upward and over my head was a glowing, blue trident. Campers around me began kneeling, except Clarisse, who I realized still had a spear at her throat. I dropped it.

"Hail, Lyrical Pandore. Daughter of the Sea God."

"Shit." I heard Percy mutter under his breath.
