Chapter 1: Who is this?

Percy's POV

It's been a year since the Gaea "incident." Another year at Camp Half-Blood. I still can't believe I've been here for five years. Sure, every year was like a plot for a book series, with all the quests and baddies, but it's been fun... in a 'seeing your live flash before your eyes' kind of way. But every year, I can't help but feel guilty knowing that I did all of this without her by my side.

I zoned out looking at the younger demi-gods playing together. I can't help but see her and I playing just like they are. I sigh, softly, remembering how we didn't play that much together in public. 'I wish things could've been different.' I thought to myself. 'I should've been with her more, if I did then she wouldn't have-'

'You shouldn't blame yourself on something that happened years ago. It wasn't even your fault.'

I jump slightly and look around. "W-who was that?," I ask to no one in particular. After seeing no one next to me, I lay down and gaze at the sky through the camp's barrier. That voice... It sounded familiar. But why? Before I went deeper into my thoughts, I saw a beautiful girl with gorgeous blonde locks and gray pupils block the sun from my eyes.

"Hey, Wise girl." I say to the girl with a smile.

"What are you doing, Percy?," Annabeth asks, ignoring my greeting. "You do know we're supposed to watch the kids today, right?"

I give her a smile and a nod. "Of course, I know that. I was just, uh.. stretching." I chuckle nervously.

Annabeth looks at me, obviously unfazed at the excuse, as she sighed. "You were thinking about something."

"Well, uh..."

"It was about her, wasn't it?"

Well, that didn't take too long.

I saw her gaze at me grow concerned at my silence. She soon sat beside me, on the ground as I sat up. "You know, it's not you fault, right?," She asked. When I sighed, she started to rant, but I soon found myself listening to her voice. 'It wasn't her...'

Once again, my thoughts were interrupted as one of the kids caught our attention. "Um.. Percy, Annabeth?" We turned to see a little girl with dirty blonde hair, a daughter of Apollo probably.

"Is something wrong, Lilian?," Annabeth asked.

The little girl, Lilian, nodded as she pointed at the sky. "What's that?," She asked. We looked up at the sky to see something... falling?

Well, it's obviously not a bird.

"Really, Percy?" Annabeth rolled her eyes at me.

"What? Did I say that outloud?" I ask. Lilian chuckled.

Annabeth sighed and shook her head, before turning her attention back to the falling figure in the sky. "It looks like... a person," She said, "And if that's the case, we need to try and catch them!" She quickly got up and ran towards the center of the camp, with me following right behind her.

As the figure got closer to the ground, I notice the figure being a girl. "Are we going to make it in time to catch her?" I ask to myself. Maybe if I can get Blackjack!

Blackjack!

Sorry, Boss. I'm eating sugar cubes right now.

BLACKJACK!

Yesh, fine. I hear him sigh. I'm on the way, boss!

After a few moments, he flew by me. "Alright, I'll try to get her on Blackjack," I explain to Annabeth, as I get on Blackjack, "If I can't get her, try to catch her on the ground, okay?" When she gives me a nod, I go up in the air towards her.

"Okay, Blackjack. We need to be careful." I tell him. As we get closer, Blackjack stops and starts to hover in the air.

"What are you doing? Why did you stop?"

She told me to, boss.

What?

I look at the girl falling closer to the camp ground. I told Blackjack to land to where Annabeth was, who was around a crowd. "What happened?" She asked.

"Blackjack wouldn't get close enough to her for me to get her." I explained.

"What? Why?"

I shrugged, still looking up at the girl in the sky. When she was about to hit the ground, a net of water appeared and caught her. I blinked. Wait, what?!

"Percy, are you-?" Annabeth looked at me, confusion forming in her voice. I shake my head, in response.

"That's a smart move though." I say, admiring the water net.

As soon as the net appeared, it burst as the girl was gently on the ground. The crowd of teens suddenly surrounded the girl. Soon, laughter was heard in the middle of them. A genuine and cheerful laugh. When Annabeth and I finally got through the crowd. We saw the girl, laying on the ground, laughing and then start coughing after.

"I almost thought I didn't have enough energy to do that!" She said with a relieved sigh, after she caught her breath. She got off the ground, back turned in my direction, and patted away the dirt off of her. She noticed the crowd of people around her. "Um... Hi?," She said, nervously, looking around. I heard people gasp as she looked at them. I wonder why.

Then she turned to me. I took the time to get a good look at her. She had on a cyan to mint ombre colored tank top, that was ripped and torn, showing half of her stomach (and zeus almighty, you can grate gold on those abs). She had on dark ripped jeans too. Her hair was mid-back length, dark brown hair (that looked more manageable than mine) and her eyes. They were a bright sea green like mine. Could she be-

Suddenly a wave of water shot towards me. Shocked, my reflexes made me control the water to rush above me and the people behind me. She smiled and walked over to me. "So, you're a child of Poesidon?" I nodded. For some reason, I couldn't find my voice or confidence to speak. Her smile grew wider. "Percy Jackson, right?!," She said, her voice obviously helped show her excitement.

"Y-Yeah."

Silence

She suddenly hugged me. "It's so good to see you again! I thought I'd never see you again," She cried out, hugging me tighter. I looked over at Annabeth, who sent me a look that could kill any man.

"I'm sorry, but who are you?" I ask.

I felt her tense before letting me go. "You don't remember me?" I shook my head and saw her facial expression deflate slightly. "That makes sense, you were still a little shocked after what happened. I'd be surprised if you did remember me."

She let go and put her fist against my chest. "It's nice to finally get a chance to properly meet you, Percy Jackson. You can call me Lizabeth!"

"I'm guessing short for Elizabeth?"

She nodded with a smile, "Yep, but you can call me Liz or Beth."

I nodded and smiled back. Her smile is pretty contagious.

"Now, Do you know where Chiron is? I need to tell him something important," She told me, shifting the mood from cheerful to completely serious. I was about to say something until Annabeth came in.

"And what do you need Chiron for, Elizabeth?" She said, spitting venom when she said her name.

"Annabeth, good to see you again. You know i can't tell you my business with Chiron. It's only between him and I for reasons you wouldn't understand." Liz stated in a 'matter-of-fact' tone.

"LIZ!"

The tense atmosphere was broken by a bunch of kids, who all toppled themselves on the brunette. I mentally sighed in relief. I looked to see Liz on the ground laughing and talking to the kids. After a while, She got up and told them she had to see Chiron, making them disperse.

"Alright, Percy, let's go to Chiron!" She said, patting my shoulder. "Before I pass out." I heard her whisper. I nod and help her to Chiron.

Now that I think about it, Liz is a Daughter of Poseidon. I guess she's my half sister now. This summer will be intresting.
