A/N: So, I bought the PJO movie today, and while I was watching it, i had to write a story about Percy having a twin sister, I couldnt help it. I'm still working on my other stories, but want chapters to be longer, so its taking longer to update. If you review each chapter of this story, I'll give you a preview (if you say so in the review) of the chapter im working on of Worthy Of Athena, which is the same kind of story, except Bella Swan is Annabeth's sister. So, that rule will go throughout the story. BTW, im going by the book, but might do another, if you want, by the movie.

Disclaimer: I do not own Percy (the hot hunk who looks just like my cousin, but older, no joke) but i do own Alala, Percy's twin.

Chapter 1

My name is Alala, and me and my twin, Percy, never wanted to be half bloods. We are in huge danger, being the children of a god of the big. We watched many grusome things, and dont ever think you want to be a half blood.

Keep reading if you want, if you're into people dying in nasty ways. Hell, I encourage you too. It's pretty awesome for me, a girl who was named after the god of wars' sister. I now know why. And Percy, named after the greek hero, Perceus. The names fit our personalities, but then they totally dont at the same time. I make friends easy, but decide to hang out with Perc and Grover in school. I care for my brother and close friends, and dont pick fights as much as i'd like too. I like to scowl Percy from afar while he's in trouble, more than fight with him. Unless it's monsters or gods, i mean serious times, then I wont leave his side. Anyways, read on! And... hope you dont have nightmares.

I'm Alala Jessenia Jackson, and I'm 14, along with my twin Percy. We have dark brown hair and bright, bright green eyes. Mine is long, silky and straight with a little wave to it, and side bangs down to my brow. We went to Yancy Academy, a school for troubled kids. Yep, we're troubled.

I think I could start my story when we went to Metropolitan Museum of Art in Manhatten to look at Greek and Roman history. Personally, I love Greek, so i had high hopes, especially since was leading this trip. He's our Latin teacher, a middle aged man with curly brown hair and a wheel chair.

I think that on this field trip, Perc wouldnt get us in deep shit. Man, was I wrong!

The whole way there, Percy was trying not to yell at Nancy Bobofit, a red headed, freckled poor excuse of a child, as she threw pieces of her sandwich at Grover, our best friend. I watched her with a glare as I talked to Percy from the seat in front of him. I couldnt do anything more because Percy got us on probation already.

"I'm gonna kill her..." Perc muttered.

"Percy..."I warned in a strict voice.

I glared as Grover tried to catch a piece in his mouth, but ended up with it in his curly brown hair. Percy tried to get up, mumbling something about decking her, but I scolwed and Grover pulled him back down.

"Percy... you already have us on probation! This time, if anyone gets to hurt someone, its gonna be me." I told him.

"Alala..." Grover started, but the bus came to a halt, and I turned away, and got off the bus.

As Mr. Brunner led the tour, i was amazed by how old and... well... amazing it all was. I could tell Percy was trying to concentrate, as was I, but people kept talking and Mrs. Dodds was giving us the evil eye. I glared back till Perc was aked a question.

"Did you have a comment, Mr. Jackson?"

"What'd I miss?" I nuged Grover.

"Percy almost freaked on Nancy."

I glared at Percy.

"Will you tell us what this represents, Miss Jackson?"

"Uh, ya, sure. Thats Kronos eating his kids."

"And he did this why?"

Percy answered. Mr. Brunner nodded, as a girl said "Ewwwee!"

I rolled my eyes, as Mrs. Dodds led us outside. I got pushed twice by guys acting like idiots, and they all ended up on their asses. I smirked.

"Miss. Jackson, can you reconized this picture?" Mr. Brunner asked.

"Thats Ares, and his sister, Alala. She was pretty." I added, as some guy muttered something about Alala and Alala both having alot in common, like their hot looks. I ignored it, but he knew he was busted when I said that.

We continued outside. The class gathered around the steps as I watched the clouds above come in and turn darker. Percy and Grover sat next to me and ate their lunches, talking. I wasnt hungry, and was about to tell off the guy who was staring at me when Nancy came and dumped her lunch on Grover's lap.

"Opps!" Her and her friends snickered.

"Bitch." I said. She looked at me and I stood up, only to pulled down by Percy, who looked very, very angry. I heard a wave in my ear, and next thing I knew, me and Percy were glaring at Nancy, stanging up, as she flew into the fountain.

"Alala pushed me!" She screamed.

"I did not!"

Mrs. Dodds came in and looked at Percy. She may hate him, but she wont even look at me. "Mr. Jackson?"

"I pushed her." He said, looking at me. I stared.

She made sure Nancy was okay, then turned on Percy, looking like a kid on Christmas morning. "Come with me."

Percy stood again, as did Grover. "I pushed her!" He said. Grover was scared to death of her, why would he say that?

"No, you didnt Mr. Underwood."

"But.." We both protested.

"Zip it, Jackson. You will both stay here!"

Nancy smirked. Me and Percy gave her the twin you'll-get-it-later stare. "Now!" Mrs. Dodds screamed at Percy. He fist bumped me as I sighed and sat down, running after Mrs. Dodds.

As soon as I sat down, I had an uneasy feel in my stomach. I twisted and turned, and not because of my ADHD. Gover looked as worried as I felt. Looking around, I noticed Mr. Brunner wasnt around anymore, and I was the only one who looked actually scared about that. Why? Well, wasnt he supposed to be watching us?

I heard a very earpiercing screech from inside the museum, followed by a "Die, honey!"

I looked around, no one heard it, and Mr. Brunner was back in his spot. That didnt help, neither did the fact that Grover was looking at him, very worried. I jumped up and ran towards the continueous screech.

"Alala!" Grover yelled, but I kept running.

Run, a voice in my mind told me. Go! In the Greek and Roman section! The gallery with the Gods!

I ran harder, and my heart pounded. Sliding into the room after taking a corner, I saw a thing with yellow fangs, claws, and leathery wings lung at Percy. I froze, and suddenly knew that was Mrs. Dodds.

He uncapped a ballpoint pen, and stood the there, obviously in terror.

"Percy!" I screeched. She looked at me, and Percy swung. The blade went through her body, like it was made of water. I thought it wouldnt work, until she exploded into yellow powder.

We were alone, and Percy now held the ballpoint pen again. "Alala." He breathed, and ran to me. I hugged him as I let the tears fall from my eyes. What was that? It almost killed Percy. Why was it after him? It almost killed him...

"It almost killed you."

"So it wasnt a dream."

I shook my head, even though it was a question.

He pulled me back outside, his hands trembling. I went and sat by Grover, asking him where Mrs. Dodds was. He said he didnt know a Mrs. Dodds. As Percy went to give Mr. Brunner the pen, I asked around if anyone knew. I was starting to get freaked out, no one knew.

I started towards Percy. "Percy, there is no Mrs. Dodds. As far as I know, there was never a Mrs. Dodds in this school. Are you feeling alright?" Mr. Brunner asked.

We stared at eachother.
