A/N: I'm not sure, but I think I would make it up to the first five books, before quitting. I never wrote in first-person before, so forgive me for mistakes.

I got the idea from January Lily's fic: From the Edge of the Deep Green Sea.

The face-claim for Ariadne is Madison Davenport.

Chapter 1: My Math Teacher Is a Monster, Literally

Before I get to the part of my unfortunate, almost near death experiences, I'll give you some back-story about me.

Okay, my name is Ariadne Jackson, the twin sister to Percy Jackson. I'm younger than him by six hours. I also prefer to go by Aria, just like how my brother goes by Percy, instead of going by his full name, Perseus.

I don't think that's good enough.

All right, let's see...

I go to a school called Yancy Academy. Well, I used to go to a school called Yancy Academy, a school for troubled kids.

That's not good enough, either.

Okay, the whole Yancy Academy being for troubled kids is because, well, I am a troubled kid. I have ADHD and dyslexia, so I suppose that makes me troubled. I also think the fact that I listen to music like Metallica and Mötley Crüe, wearing all black clothes, and apparently having a bad attitude makes me a troubled kid. Maybe it's because most adults, except for my mother, don't understand my dry humor and sarcasm. I suppose that makes me a troubled kid. Okay, now onto the near death experiences...

It all started on a torturous field trip to Metropolitan Museum of Art, to look at Greek and Roman artifacts.

Our tour guide was Mr. Brunner, a thinning, scruffy bearded, frayed tweed jacket wearing, coffee-smelling, motorized wheelchair driving, middle-aged man. He also happened to be our Latin teacher.

He led us through the Greek and Roman exhibits. There was black-and-orange pottery that supposedly survived two to three thousand years. I suppose it was cool, if you enjoyed that type of thing.

I wasn't paying much attention, so I wasn't sure what happened, when I heard, "Will you shut up?" being echoed loudly in the museum. Everyone laughed, besides Mr. Brunner. It was Percy and I was sure that he wasn't talking to Mr. Brunner because he was the only teacher who Percy respected.

"Mr. Jackson, did you have a comment?" Mr. Brunner asked.

"No, sir," Percy replied. I looked over to see that Percy's face was bright red. I saw Nancy Bobofit and two out of three of her lackeys, Lindsey Stone, and Julia Costello, standing next to him, giggling. Probably over something stupid, I bet.

"Perhaps you'll tell us what this picture represents?" Mr. Brunner said, motioning to a stele.

"That's Kronos eating his kids, right?" Percy responded.

I tried to pay attention, but in my defense, it was kind of hard because my pre-algebra teacher was suddenly at my side, grabbing my arm roughly. Her fingers were digging into my arm, which was way to sharp to be considered normal.

Her name was Mrs. Dodds and she had this annoying habit of calling everyone honey. I have no clue who, in their right mind, would marry her. I don't recall seeing any pictures of her husband, although I'm sure that Mrs. Dodds killed him. She was from Georgia and she always wore this leather jacket, despite being ancient. All right, she was fifty and she was mean as hell. Once she made Percy erase answers out of text books and I once had to copy down an entire dictionary in composition notebooks. Sometimes composition notebooks haunt my nightmares. She showed up halfway through the year when our previous math teacher had a nervous breakdown.

"What?" I asked, trying to sound nice, in case she gives me detention and has me write the entirety of Harry Potter and the Order of the Phoenix in composition notebooks, or make me clean the chalkboard erasers.

"Let's go, honey," Mrs. Dodds said, tugging on me, as if trying to get me to leave the group.

"Why?" I asked, but Mrs. Dodds pulled on my arm. "Let. Go," I hissed, trying to tug my arm back.

Mrs. Dodds's hand tightened its hold on my arm, like she had a steal grip. I can feel her nails digging into my arm.

"Now, honey," Mrs. Dodds hissed back, trying to pull me back again.

"Stop it!" I shouted, my voice echoing in the chamber. It seemed like all eyes were now on me. However, Mrs. Dodds was standing right by Mr. Brunner, giving me the evil-eye. I looked down, trying to blink the embarrassment tears out of my eyes. I was sure I was as red as Percy was.

I looked back up to see that Mr. Brunner looked like he was going to say something. Mrs. Dodds was still death-glaring me. It was impossible that Mrs. Dodds was now standing over there by Mr. Brunner, as if she hadn't tried to kidnap me. She couldn't have moved that fast.

"It's time for lunch," Mr. Brunner said. "Mrs. Dodds, would you lead us back outside?"

We started walking away, when I heard, "Percy and Aria Jackson…"

At that, my heart started beating rapidly, and I got the feeling like I was going to throw up. My face was starting to burn and I just knew that he was going to say something about my behavior. I didn't want to talk about it, not when I seemed to be hallucinating. I did the most screwed up thing by running, shouting, "Emergency!" while at it. I ran straight to the nearest restroom and hid in the closest stall. I leaned against the door and tried to take some deep breaths to calm down.

I wasn't entirely sure what Mrs. Dodds wanted and why she tried to drag me away from the tour group. I didn't even know how Mrs. Dodds even ended up standing beside Mr. Brunner when she was next to me.

It's just what my mother needed, a daughter that hallucinates on to top of having ADHD and dyslexia.

I left the stall and went to the sink. I pulled my sleeves up on my long-sleeved shirt and noticed three dark red indents on my arm, like talon marks.

What the hell? I thought, looking at the indents. Mrs. Dodds must've made them when she was trying to kidnap me. I splashed water on my face, trying to refresh myself. I felt a lot better after that. I was drying my face off with a paper towel when the door to the restroom opened.

"Well, there you are," said a false sweet voice.

I rolled my eyes. It was Emily Lancaster, Nancy Bobofit's third lackey and second-in-command.

"What do you want, Lawson?" I purposely called her by the wrong last name, because I wanted to show her how insignificant she was too. Yeah, I was being petty.

I'll admit it. I used to be in Nancy's inner circle of friends. It lasted for three months. The reason why they kicked me out?

I saw Emily's 'boyfriend', Derek, an eighth grader, kissing some girl. I told Emily about her 'boyfriend' cheating on her. As a thank you, I ended up getting lunch dumped on me by Emily and Nancy. Emily claimed that I was just trying to break her and Derek up and still thinks that, despite me repeatedly claiming that I never liked Derek.

To be honest, I don't think Emily and Derek were in a relationship, because I never saw them together. Nancy took Emily's side because they've known each other longer. In return, Nancy bullied Percy, which extended to Percy's best friend Grover, while Emily bullied me.

"I saw your little freak out earlier," Emily continued in that false sweet voice. One thing about Emily is that she's a compulsive liar, which ended up creating the whole Derek Incident. She dropped the false sweet tone, "You just can't handle it when the attention is off of you, can't you?"

"I don't care if I'm not the center of attention, Emma," I snapped. I purposely called her the wrong name, just to show how insignificant she is to me.

"You're a dirty liar," Emily snarled back. She stomped up to me, causing me to back up into the wall. She was taller than me by two inches. I, personally, think that she had gotten held back a grade. "We both know that you and your brother stupid just want to be the center of attention. We both know that's why you both 'act out'."

I balled my hands into fists and glared up at Emily. I sort of blacked out at my brother being insulted. Emily's scream of surprise was what brought me back. I saw that Emily was soaked from water from the sink. The pipe was broken and I didn't stick around, because I ran outside to where the others were eating lunch.

I stopped and started to try to get my breathing back under control. I wanted to act like nothing happened. I spotted Percy standing on the fountain, waving me over to him.

We both had black hair and sea-foam green eyes.

I walked over, trying to avoid Mr. Brunner who sat at the base of the handicap ramp. He was eating celery and reading a book. He had a red umbrella out, giving him the impression that it was a motorized café table. I didn't want to run into him and have him give me some belated lecture.

I was trying to act like nothing happened, and sat next to Percy on the fountain. He was sitting with Grover, who also happened to be Percy's roommate.

I wasn't close with my roommate, Kate, because we butted heads so many times over the state of our dorm. I wanted everything to be neat and orderly, because I'm such a neat-freak, but she happened to be the runner up to the first place trophy of slobbiness, (is that even a word? Percy says it isn't,) after my step-dad, Gabe.

Kate let me clean up her side of the dorm, but it's like I turn my back on her for a second, only to find her side a mess again. I do love cleaning, but that's going too far. I think Kate did it because my fidgeting distracts her and cleaning helps distracts me, aside from my cross-stitching.

I exhaled blowing a strand of hair from my face and looked up at the sky. The sky was blacker than I had ever seen and it looked like a storm was brewing. The weather seemed troubled because one day we had massive snow storms and the next, we had floods. I held out my hand to Percy, "Lunch me." He slapped a sandwich in my hand. "Thanks. What did Mr. Brunner want?"

"To tell us that what we learn is vitally important to us and that he expects the best out of us," Percy said.

I groaned through a mouthful of peanut butter and jelly sandwich. "Of course he does." It's nice that Mr. Brunner wanted us to do better and that he pushes us to do our best. It's nice of him not to write Percy and me off as lost causes because of our ADHD and dyslexia, like our previous teachers did. However, it's frustrating at times because it seems like we can't keep up, especially we keep getting sidetracked and miss important facts. It also frustrates me when I almost fail, because it feels like I'm disappointing and failing him.

"What was going on with you in the museum? Why did you yelled 'stop it?' Was Emily bothering you?" Percy asked, as he got up to look for Emily.

Brothers are strange people to have. It's like, one minute, you're arguing with them and the next they have you laughing. One minute, it seems like they throw you under the bus, and the next, they're ready to defend you even though they know that you can take care of yourself.

I sighed, "No, it wasn't Emily. It was Mrs. Dodds. I swear, it was like she was trying to kidnap me." Grover made a weird 'pfft' sound that caused me to look at him. I looked at Percy, "She scratched me, see?" I pushed my sleeve up but the scratches were gone. I looked at my arm.

"Maybe they faded," Percy said, shrugging. "You know how us Jackson seem to heal faster than usual."

"Yeah," I admitted. "Emily cornered me in the restroom. A sink pipe exploded and sprayed her with water." Grover made that weird throaty blah-ha-ha sound, like he had phlegm in his throat. I looked at him sharply. "What is the matter with you?"

"It's funny," Grover said, his face reddening.

I sighed again, "Don't tell Mom, Percy."

That was our code when something happens during field trips. At our fifth-grade field trip, we went to the Saratoga battlefield; this Revolutionary War cannon went off and hit the school bus. Percy got in trouble. During that field trip, I got into an argument with a teacher in the restroom and the toilet erupted, doing some cool geyser effect. I don't know why I got in trouble for that. At our fourth-grade field trip, I somehow got in trouble for trying to steal sea shells from Marine World. I still don't know how the sea shells got into my backpack. Percy ended up sending our class into the shark pool because he somehow hit the wrong lever, causing the catwalk to disappear beneath our feet.

Nancy, Julia, and Lindsey walked up to us. Nancy was smirking and holding two half-eaten sandwiches, a crinkled chip bag, and a milk carton. I looked for Emily, who was talking to Mrs. Dodds. She was probably telling her about what happened in the restroom, or maybe it was an attempt to distract her from what Nancy was going to do.

"Oops," Nancy said trying to sound innocent as she dropped her lunch right into Grover's lap, as if he was a convenient trashcan. She smirked at us and then she looked at me. In a false sweet tone, she said, "I heard what you did to Emily in the restroom, Aria. If you didn't 'notice', she's over there telling Mrs. Dodds what happened. I know how much you love attention, so Mrs. Dodds will be here in a few minutes to give you just what you always wanted."

My mind went black and all I can hear was a roaring sound.

"Percy and Aria pushed me!" Nancy yelled from behind me. Percy and I turned to see that Nancy was sitting on her ass in the fountain.

I realized that I was strangling my half-eaten sandwich to death. I couldn't have pushed her because I was murdering my sandwich. But I did black out, so I could have done it, sat down, and proceeded to squeeze the life-force out of it.

Mrs. Dodds suddenly appeared right in front of us with Emily in tow. Emily was smirking and Mrs. Dodds told the both of them that she will get them new shirts from the gift shop. She turned to Percy and me, looking triumphant.

Do I want bluebells or forget-me-nots at my funeral? I wondered. You see, when Mrs. Dodds first came in, she automatically thought that Nancy was god's greatest gift on mankind, while Percy and me were the devil's worst gift on mankind, so she treated us as such.

"Wait!" Grover yelped, "It was me! I pushed her and rigged the sink!"

I was surprised because Mrs. Dodds scared Grover and here he was, taking the blame for us. Especially taking the fall for me, even though I couldn't exactly think of Grover as a friend. I thought of him as an acquaintance. Yes, I hung out with Grover more, since my friendship with Nancy ended, but I still couldn't think of him as a friend.

"I don't think so, Mr. Underwood," Mrs. Dodds replied.

Grover said, "But—"

"You. Will. Stay. Here." Mrs Dodds ordered and I could've sworn I saw her eyes flash. But that was impossible, because eyes don't flash.

First Mrs. Dodds appearing to stand by Mr. Brunner when she was right beside me, then the exploding sink, then us supposedly pushing Nancy into the fountain, and now with the flashing eyes? I really need to get my brain checked out.

"It's okay, man," Percy reassured Grover, "Thanks for trying."

I nodded, "Yeah. It's not the first time we got in trouble and it's probably not going to be the last."

"Honeys, now," Mrs. Dobbs ordered.

I looked over at Nancy and Emily to see that were smirking victoriously. I turned to face Mrs. Dodds, but she wasn't right there in front of us. She was at the top of the stairs, gesturing for us to hurry up and follow her. How did she get there so fast?

We followed after Mrs. Dodds. Halfway up the stairs, I happened to look back at Grover.

I wasn't sure what his problem was, because we've been in trouble with Mrs. Dodds loads of times. It looked as if Percy and I were walking to our funeral.

"Hurry up, Aria," Percy said. "We don't want to keep her waiting, in case we anger her even more."

I turned to face Mrs. Dodds, but she wasn't there. Very eloquently, I said, "Uh…Where did—?"

"She's inside," Percy said. We followed Mrs. Dodds inside. She was at the end of the entrance halls. How was moving so fast?

I tried to rationalize it as my ADHD acting up. Part of my memory couldn't keep up, so it's like puzzle. One piece was missing, which left a hole in the picture. That's hole my mind works.

"She's going to make us buy them shirts from the gift shop, isn't she?" I asked.

"Better than detention," Percy replied.

"True, but I don't want to face the wrath of Gabe," I said. "I hope they have something that's on clearance." Our step-dad was big on 'saving money', he says it while he buys cigars and beer. He also says that while he gambles the money away in his poker games.

We finally caught up to Mrs. Dodds, who was in the Greek and Roman section. She was standing in front of a frieze of the Greek gods and making this weird growling sound. I heard that sound once. It was directed at me.

"You two honeys have been giving us problems," Mrs. Dodds said, not looking back at us.

I was pretty sure that Yancy Academy was trained to deal with troubled kids, so I wasn't sure how Percy and I were giving them problems.

I decided to play it safe by just agreeing with Mrs. Dodds.

"Yes, ma'am," Percy and I said in unison.

Mrs. Dodds tugged at the cuffs of her leather jacket. "Did you two really think that you would get away with it?"

Okay, so maybe I did push Nancy in the fountain and somehow broke the sink pipe. "I'll apologize to them, if that's what you're asking."

"We'll—we'll try harder, ma'am," Percy said at the same as I spoke.

I wasn't sure what Percy meant by that and looked at him. He remained impassive.

Thunder boomed, making the building shake. I grabbed Percy's arm, worried that the building will collapse in on us.

"We are not fools, Perseus and Ariadne Jackson," Mrs. Dodds said.

I cringed at the use of my full name. I didn't know what she was talking about. I sure as hell didn't know what this whole 'we' business was about. I don't think she was talking about the school board.

"It was only a matter of time before we found you out. While we weren't expecting twins, it does make sense of things. Confess and you both shall suffer less pain," Mrs Dodds continued.

Confess to what? Spraying Emily with water from the restroom sink and pushing Nancy in the fountain? What makes sense? The fact that Percy and I share the same last name? Suffer less pain? What did she mean by that? Unless she found out about my underground cross-stitch store, but did that deserve the extreme punishment of pain? I needed to make money somehow.

"Well?" Mrs. Dodds prompted.

"Uh…" I eloquently started.

Percy started, "Ma'am, we don't—"

"Time's up," Mrs. Dodds hissed. Her eyes began to glow, her fingers stretched and turned into talons. Her jacket melted into large, leathery wings like the wings of a bat. She now had a mouthful of yellow fangs.

I knew she was a monster, I thought as I backed into a wall. Okay, I really didn't think that she was a monster-monster, just a terrible person-monster.

Mrs. Dodds flew straight at me, her talons bared, and snarling, "Die, honey."

I heroically screamed and I bravely fell to my knees, right as Mrs. Dodds hit the wall, talons-first. I didn't fall fast enough, because I felt a talon graze my cheek and it exploded with pain and blood. I knew it was blood because it dribbled down. I grabbed my cheek in pain.

"Hey, Ugly! Don't touch my sister!" Percy shouted and I damned him to hell because Mrs. Dodds dislodged herself, before flying straight towards him.

It could've been the pain talking, but I saw him swing a bronze sword right at Mrs. Dodds, slicing her in half. There was a loud screech and the smell of sulfur. There was a yellow powder on the ground and there was a chill in the air. Percy was now holding a ballpoint pen and we were alone.

"Aria, are you all right?" Percy asked, helping me to my feet.

My cheek still felt like it was on fire as I touched the cut, which didn't feel deep. "How bad is it?"

"It's not that bad," Percy said. "You'll probably end up with cool looking scar."

"Do you think it'll make me look tough?" I asked.

"Yeah, a real street fighter," Percy said.

I think he was joking. "Do I need a band-aid?"

"I don't think so," Percy said. We quickly left the museum.

It was raining. I held out my arms, closed my eyes, and lifted my face to the sky. The rain instantly made me feel better. I had always loved the rain.

"What was that?" Percy asked me.

"I…have no idea," I responded and the memory slammed down on me.

Grover was sitting by the fountain. He was now holding a museum map over his head. Nancy and Emily were standing by the fountain.

"I hope Mrs. Kerr whipped your asses!" Nancy shouted and looked straight at me. "At least she got to you, Aria!"

Did…did I hear correctly? I thought, did she just say Mrs. Kerr? I looked at Percy.

Percy looked confused, "Who?" He sounded just as confused as I felt.

"Our teacher, duh!" Nancy said as if Percy was stupid.

"What are you talking about?" I asked confused. At least my cheek wasn't burning anymore. "Who's Mrs. Kerr?"

"I always knew that there was something wrong with you two," Nancy said, wandering off with her friends. They were laughing, probably about how dumb Percy and I were. Or maybe they were joking and laughing about how they got us good.

Percy and I went over to Grover. Percy asked, "Where's Mrs. Dodds?"

Grover didn't even look at us as he said, "Who?"

"That's not funny!" I replied shrilly. Why were they acting like Mrs. Dodds didn't exist? Why did Grover end up helping Nancy with this stupid little prank?

"Yeah, this is serious," Percy said.

Thunder boomed overhead and I saw Mr. Brunner who was still sitting under the red umbrella. "Let's go ask Mr. Brunner. Maybe he might tell us."

We walked over to him, making him look up. For a few seconds, it looked like he was distracted. "Ah, that would be my pen. Please bring your own writing utensils in the future, Jacksons." Percy handed Mr. Brunner his pen, but Mr. Brunner was looking at me. "I should also add that you two aren't supposed to be rough-housing inside the museum. You two are lucky that you didn't break something or get banned or fined."

I thought, rough-housing? I looked at Percy confused.

"Sir, where's Mrs. Dodds?" Percy asked.

"Who?" Mr. Brunner asked looking at us in an almost blank manner.

"Our pre-algebra teacher, Mrs. Dodds," I told him.

"The other chaperone," Percy said, as if that would help Mr. Brunner remember.

He frowned at us and sat forward, looking concerned. "Percy, Aria, there is no Mrs. Dodds on this trip. As far as I know, there has never been a Mrs. Dodds at Yancy Academy. Are you two feeling all right?"

I nodded, even though I didn't feel all right. All I know was that something wrong was going on, but I didn't know what it was. Maybe it was some school-wide prank where Percy and I were the poor unfortunate fools were the targets. Maybe it was supposed to be a late or early April Fool's Day joke. Maybe when we got on the bus, everyone would yell, "You go punk'd!" at us. Yes, that would be great, but how would that explain Mrs. Dodds turning into a monster?

Percy and I got on the bus and sat down at the very back, then a smiling blonde woman that I never even seen before walking on the bus.

Unfortunately no one turned to yell, "You got punk'd!" at us. I stared out the window the rest of the way back to Yancy Academy.

The good and bad news was that the scratch on my cheek had disappeared. On one hand, at least I don't have a scar that I have to explain away to Mom, and on the other hand, I didn't have proof that my math teacher had turned into a monster and attacked my brother and me. On a third hand that I don't have, at least I had Percy who seemed to be just as confused as I was.

I didn't know it at the time, but change was upon us, like a tidal wave.

A/N: I was looking for names to use and decided on Ariadne, because she seemed to have a happy ending, like how Sally named Percy, because Perseus is the only Greek hero to have a happy ending.

Although, in one myth, Ariadne killed herself and Dinoysus went to the Underworld to bring her back to life and made her an immortal or a goddess. In a different one, Dinoysus told Thesus to ditch Ariadne because Dinoysus fell in love with her, so Thesus had no choice but to leave her behind, because it was orders from a god. I think she was killed by Perseus or Artemis, but either way, Ariadne was brought back from the Underworld and either became an immortal or a goddess, due to her help in the Labyrinth and weaving.

Well, in this book series, Dinosyus healed Ariadne's broken heart and they got married, and she's either an immortal or goddess, so she still gets to have a happy ending.

I also had the idea of Percy having a twin sister a while back, but I never wrote it out. So, when I read From the Edge of the Deep Green Sea by January Lily, I decided to write my idea out, because I was inspired by it. If you hadn't read it, I highly recommend that you do read it.
