A/N: Just so you know, I have read the first book, (don't hate me, but the first book only,) and I have the second one, but I haven't read it yet. I have seen the second movie though, but I know they'll be different considering the first one. This story takes place before the second book, but after the first. So, the second book takes place the third summer instead of the second. I am one who liked the book more than the movie. It wasn't bad, but I just liked the book more. If the movie wasn't based off a book it's be pretty good. The characters will be the same age as they are in the movie. So here are the ages: Percy- 16, Annabeth- 16, Ria- 16, Grover- 28-ish? around there, and I think that's it.

I don't think Luke will feature in the story. Unless you guys want him to come back as either another threat, or an ally. Oh, and Percy may or may not be a bit OOC because of the way he dislikes Ria, but I kind of need that for this story to work.

***By the way, can anyone catch the reference to the tv show FRIENDS in this chapter?

Disclaimer: Seriously, do we need to put this?

Percy's POV

Summer. It was my favourite time of the year. Why? I was finally able to go back to Camp Half-Blood. The safe haven training camp for Demigods. It was the last day of school, and I was staring at the clock. Hey, I wasn't the only one. No one was paying attention to the lesson anymore. There was five minutes left! My ADHD was kicking in. I had the worst teacher for English. He was monotone, dull, and not very interesting. Not to mention that this was my worst class. I looked back at the teacher who was unnecessarily going over the days lesson. It was the last day of school for crying out loud, why teach anymore? No one here payed any attention. I just barely did everyday. In this class my mind kept wandering back to Half-Blood. I had my first summer there last year. This would soon, in about four minutes, be my second.

I felt someone poke me in the arm. I turned to see Grover, my best friend and protector outside of Half-Blood. He made a small gesture at the clock. Whoa, five minutes gone already. Just thirty seconds left! But those thirty seconds always felt like an eternity. Then the glorious bell rang! We were free!

Grover and I made our way to my house. "Man Grover, I can't wait to start packing!" I said happily. Grover laughed. He kept up easily, even though he had to pretend to use crutches. Being a satyr was hard work. "I know, I know. Remember that we don't leave until morning though." he said. While we were walking fast, someone bumped into Grover. "Watch it man." said the guy. Nice man. "How about you watch it? I'm the one on crutches!" called Grover. He scoffed. "Some people. They just don't have respect. So. What are you gonna do when we get to camp?" he asked. I smiled.

"First, I'm gonna sleep. I remember the last time the trip was exhausting." I said, Grover laughed remembering the Minotaur. "Then I'm gonna hang out with you and Annabeth. Unless you have some protector duties to attend to." I said. Grover suddenly stopped walking. I stopped as well and looked at him. He had a worried expression on his face. "Uh, Grover?" I said. I waved a hand in front of his face.

"Uh, yeah. After we get you packed, I just remembered that we have to leave tonight. Like, right after. Gotta make one stop before leaving for camp." said Grover. We kept walking.

"And where would that stop be?" I asked.

"Baltimore."

I stared at him. Seriously? That was how far away? "Well come on man, we gotta get there!" said Grover. I sighed and kept walking.

We made it to my house in a few minutes. My mom was watching tv on the couch. "Hi mom." I said as we walked in. She got up and hugged me. "Hi sweetie. How was the last day?" she asked. I sighed. "It took way too long to end." I said. She laughed and went back to watching tv. "Hi Grover." she said. I made my way to my room to start packing. "Hi Mrs. Jackson. Um, I remembered today that Percy and I have to leave tonight for Half-Blood. We have to make a stop in Baltimore before going there." explained Grover. Curious as to why we were going there in the first place, I listened in just in case it popped up. "Oh, alright. I'll pack you guys some food." said mom. The topic never popped up. I sighed silently as I finished packing. I guess I'll find out when we get there. Unless I keep pestering Grover. He'll break down eventually.

I hugged and kissed my mom goodbye, and we made are way to where Grover parked his car. Since the mortals saw him on crutches, he had to hide the car. The place he chose was the nearest abandoned ally. People left all kinds of stuff there. Grover has a car because my new step-dad Paul, decided that he should have one if he's a protector. So I guess my new step-dad is pretty okay. Especially when it came to this stuff. I threw my backpack in the trunk and got in the passengers seat. The ride took a few hours. I didn't bother with asking Grover about why we were going there. I just decided to let it be a surprise.

Sometime on the way there, I had fallen asleep. I must have been right out because I didn't wake up even when we were there. But when we were nearing New York again, I woke up to the sound of the car going over a pothole. I yawned and stretched. "Grover, what time is it?" I asked. I heard him yawn.

"Four in the morning." he said sleepily. Wait. That sounded like it was coming from the backseat. I glanced back.

I was suddenly wide awake. I looked at the person driving. It was a girl I'd never met before. "Whoa. What?" I said. I glanced back and forth from her to Grover. He yawned and fell back asleep. I grew tense. That was a nice wake up call. "Good morning." smiled the girl. She had a Spanish accent to her. She had long dark wavy hair that had a dark blue streak in it that faded to a light teal, green eyes, and tanned skin. She was wearing an orange top, jeans, and had sunglasses on her head. The girl also looked to be about my age. The girl glanced at me. "Take a picture, it will last longer." she said. I sighed and rubbed my eyes to wake up more. "My name is Ria Ula Marina Mizushima. Call me Ria though." said the girl.

I didn't really know what to say. How are you suppose to react to the fact that a total stranger was driving the car, and your best friend was sleeping in the back? "Uh huh. Okay. Um, why- why are you here?" I asked. I actually didn't know if I wanted to know that answer. She didn't answer right away though. "So what is your name?" she asked. Oh yeah. I guess I could have said that. "Uh, I'm Perseus- um, Percy. Just Percy. Uh, Jackson. Perseus- uh, Percy Jackson." I said quickly. That was weird. Why did I keep saying my actual name? I didn't like that name, so I barely used it. Ria smiled. "So uh, back to my question." I said.

"Your friend Grover told me to come with you." said Ria. I know this may sound weird, but there was just something about her I didn't like. I nodded in response to her statement. "Okay. But why?" I asked again. Ria sighed. She seemed annoyed, but didn't say anything about it. "Okay. This- this may seem strange, but- I don't know who I am or who my family is." she smiled. "I just know my name, and that I know all of the martial arts, and can speak three languages. That's it. I don't know where I came from at all. I wandered the streets of Baltimore ever since I can remember. That is until the thing called a Fury attacked me. That's why I'm here. Grover said that we were headed towards a safe haven."

I stared ahead. The thing that surprised me most was the fact that I had apparently slept through all of it. I must have been really tired.

I didn't really know what to say. I wasn't sure why I didn't like her. I should have felt some sympathy or something like that. The girl doesn't remember a thing about her past for crying out loud! But I didn't. I didn't feel anything like that. It was weird. Just, something about her irked me. "Um, I uh, I'm sorry." I said quietly. I could tell that her past was a touchy topic, so I decided to change it.

"Hey uh, do you know how to drive?" I asked. I really should have reworded that question. That one earned me a slap across the head. I could have sworn I saw Grover smile. He was awake, I knew it. "Of course doofus. What did you think Perseus, huh? That the two of us are idiots?" she said. I sighed at the fact she used my actual name. "It's Percy, and no. I just- I just wasn't sure." I said. That earned me another slap. This one was surprisingly harder. "Ow." I sighed and rubbed my head. "I thought martial arts were only suppose to be used in self defence." I said. She scoffed. "That was just barely martial arts Perseus. And besides. I was defending myself against your word." Ria said. I thought I heard Grover make a noise.

"Percy, and I wasn't trying to say that you guys are idiots. I was just- I didn't know if you had your license or not." I said. She glanced at me oddly. "Then why didn't you say it like that Perseus? I'm driving, so I have a license. If I was not driving- like you- then I wouldn't be driving. It's common sense." said Ria. Common sense. Right. I'm sure I heard Grover hold back a snort. I sighed. "It's Percy. Just Percy. So what, I'm the idiot?" I sighed. She didn't reply. I glanced at her and stared out the window. Well, that was a nice introduction to a new day. The rest of the trip was quiet. We stopped along the way so Ria and Grover could switch seats.

Finally we made it to Camp Half-Blood. But someone was waiting for us. "Grover." I said.

"What? Just go back to sleep Percy." said Grover.

"Grover there's-"

"Minotaur!" shouted Ria. "Good morning. Again." Well, she was awake. The Minotaur saw us and got ready to charge. Grover swerved out of the way, and parked the car. "Everyone out. NOW." he said. We immediately got out. Ria had trouble though. "It's stuck! It's unlocked but it's stuck!" she shouted. Grover ran to the door and pulled on it. I brought out my pen and clicked it. It turned into Riptide, and I got ready for the beast.

"What is he doing? He's going to kill himself!" shouted Ria. Gee thanks. "Way to have faith!" I shouted. I could feel her rolling her eyes. The Minotaur made a grab for me, but I dodged it and struck at it's side. It howled angrily. Somehow I got onto it's back again. I managed to break off one of it's horns, and used that to stab it like the last time. It let out blood hurdling screams as it went down. If I didn't move, I was about to be under it! I jumped off and hit the ground hard. Grover ran up to me and helped me up. "Woo! Man, you can take care of those things like cake now! That's awesome!" he said. I nodded in response. "Thanks." I said. I grabbed my bag, and we walked towards the gate to Half-Blood.

Ria was already inside the barrier, and was surprisingly taking this really well for a first timer. I could tell that she didn't know what was happening, but she'll know soon enough.

Suddenly, once I was inside the barrier, she pinned me against the wall, and started punching me. "Ow, ow, ow! What are you-" she cut me off with a punch to the head. Ow. My head smacked against the wall. Again- ow. My vision became blurry. Uh oh. Not good. I wanted to say something, but I couldn't. My mind could only think about the pain I was receiving.

"You idiot! Don't scare me like that again! That was the worst way to go about the situation! Don't you use your brain, or do you not have one? You were lucky you got out of the way before it squashed you like a bug!" she yelled. Then she surprisingly started yelling in Spanish. Luckily neither Grover or I knew the language. I don't think we would want to hear what she said. Well, apparently she didn't take all of this well. And she was taking it out on me.

"Hey, hey, hey. Easy girl. Easy. Ria- don't kill him. Save that for his enemies. Easy now. Ria, look at me, it's okay now. You're safe. We all are." said Grover. He managed to get her to stop punching me and pulled her away from me. I was quite thankful. She'd gotten me in the head a few times, and I could have passed out right then and there. I felt dizzy, and could just barely stand up. "You know she has a point. That really was the worst way to go into battle." said a familiar voice. I looked to my left, and dizzily made out the figures of Annabeth, Chiron, and Mr. D. "Anna-be-" I didn't finish her name. "Percy? Wow. Deja vu." I heard Grover say. But then I didn't hear or see anything. I blacked out.

I heard voices rush around me, but I couldn't make anything out. Was I in the infirmary? My head hurt like crazy. I opened my eyes. Bad idea. My headache got worse. I groaned and rubbed my forehead. "Good afternoon sleeping beauty." someone said. Then I heard someone else chuckle. I forced my eyes open and looked at them. "Hi guys." I said to Grover and Annabeth. I tried to sit up, but that made the pain worse. "Easy, don't move too much. You might have a concussion." said Grover. Great, what a way to start the summer off.

"What happened?" I asked. I didn't remember much. I just remembered making it to camp, and defeating the Minotaur. The other two started laughing quietly. I sighed. "What, what happened?" I asked.

"Ria beat you up for scaring her." explained Grover. I groaned.

"Turns out she has more strength than the bull men." laughed Annabeth. What? Why? How? I groaned again as my thinking made the headache worse. "What?" I said.

"Yeah, you've been out for four days. The bull knocked you out for only three last summer. Talk about deja vu." said Grover. Four days? Awe man. I'll bet that the whole camp was talking about this. Percy Jackson, son of Poseidon got knocked out for four days by a newcomer. "I didn't have time to react, she pinned me against the wall and she knows martial arts." I said. Grover snorted.

"And Spanish, and Japanese." he said.

"And you scared her half to death." said Annabeth.

"Yeah, I don't think we want to know what she said." said Grover.

Annabeth laughed. "Yeah, I only know a few Spanish words, and the ones I heard were swear words." she said.

I spent the rest of the day in the infirmary. Grover was right about me having a concussion. I felt like puking the whole afternoon. By nightfall I felt better, but the doctors insisted I stay for one more night just in case. That was probably a good idea.

By the next day, I was able to move around and go back to my cabin. Grover was the first to greet me at breakfast. "And he's back!" he said happily. I let out a breath after taking in the fresh air. "Yeah. I'm never getting another concussion again. Worst experience of my life." I said. Grover laughed. I wasn't very hungry, and Grover had eaten already, so we decided to skip breakfast. We met up with Annabeth in the training grounds. "Hey." she said. "Not much has happened after you got knocked out by Ria." she explained.

"She hasn't even been claimed yet. I'm curious as to who she belongs to. It's not Hermes." said Grover.

"Maybe it's Ares." said Annabeth.

Grover shook his head. "Nah, she doesn't seem to like war and battle that much. I can't blame her." he said.

I sighed. I didn't really want to talk about this. We walked along the shoreline of the lake. To my right, I saw Ria sitting under a tree drawing something. She noticed a dead flower near her. Ria touched the stem near the ground, and it magically healed itself and blossomed. I stopped walking. "Whoa, wait. What kind of power does she have? She just healed that flower by touch." I said, surprised. The other two stopped walking and looked to where I was staring. Ria smiled at the flower and went back to drawing.

"Oh yeah, I guess that's new." said Annabeth. "She can control plants, you know, like you can control water. Oh and she has sweet healing powers. Cool huh? Oh hey! Maybe she's a daughter of Apollo."

"This was discovered yesterday morning when she saved Clarisse's butt from falling off the docks and into the water. But Clarisse wasn't as joyful about it. I'm pretty sure that girl would have rather taken the water than the branches. She doesn't like being saved." laughed Grover. Annabeth laughed along with him. I didn't say anything. I returned to walking along the water. "Man, what is with you lately?" asked Grover. I sighed.

"I don't know. I just- I just don't trust her." I said. They looked at me oddly. I wouldn't blame them. I really didn't know why I didn't like her. "Why?" asked Annabeth.

"I don't know. I just don't. Know..." I said.

"There has to be some reason." said Grover. They weren't going to leave me alone until they had answers. The problem was, I didn't have any. "Look, I know you're going to keep asking question until you have answers, but I don't have any. So, can we please just, drop it?" I asked. I was getting tired of saying "I don't know" over, and over again. "There can't be an answer to everything." I said.

"Things don't happen for no reason Percy, we all know that." said Annabeth.

"Yeah, I know, but this time, maybe there isn't one." I said. I decided that I need to clear my head. I went back to my cabin to change for the water. I was lucky that I had the day off from training because I had just gotten out of the infirmary. After changing, I headed towards the docks. I dove in the water head first and swam to the bottom. Finally. I was able to clear my mind. But it didn't completely work.

Why did I dislike Ria so much? I didn't even know her! All I knew about her was what she, Grover and Annabeth told me. It was weird. Someone I'd just met never bugged me like this before. I was really confused about this. Sure, Clarisse and I weren't friends but we weren't really enemies either. Not that Ria was an enemy. I mean, Clarisse and I didn't exactly start off great, but we don't hate each other. I guess I didn't know if Ria hated me or not. Apparently she didn't see me in the infirmary at all, but that didn't necessarily mean she hated me. Did it? Maybe she was just working her mind around all of this.

I suddenly heard splashing above me. I looked up to see Ria sitting at the edge of the dock with her feet in the water, looking down at me. I mentally sighed and swam up. "Hi." she said quietly. I nodded and cleared my throat. There was an awkward moment of silence between us. "I'm sorry." Ria said. I looked at her. "For punching you, and knocking you out for four days. I let my fear get the best of me. I took it out on you. That wasn't right. I'm sorry, Perseus." she explained. I didn't say anything. I just nodded my head, and she smiled. She stood up, and put on her flats. She gave one last smile, and walked off to who knows where. Once she was gone, I sighed and dove back underwater.

This would be an interesting summer.

I looked up at the sound of splashing again. This time though it was... Clarisse? What did she want? With a confused look, I swam up to the surface. "Chiron has some news for you, and Annabeth and Grover were busy with other stuff, so he sent me to get you. He said to meet him at the Big House. So in other words, prepare to die Jackson." she said. I rolled my eyes at that last comment. I'm sure I haven't done anything wrong. Well, I guess I was about to find out.

After Clarisse left, I got out of the water and walked to the Big House. I braced myself for what was to come. What did I do wrong this time? Not that I've done anything wrong before... Was Mr. D just still ticked at me for beating him at cards that one time last summer? He must have been waiting for the right time to punish me or something. It was just one game, but to that guy I'm sure it's everything. That and wine which he's not aloud to have anymore. I saw Chiron and walked up to him.

"Ah Percy. Now before we get started, um, you believe that you are Poseidon's only heir." said Chiron. I gave him a weird look. "Yeah... so?" I said. I wasn't really sure where he was going with this. Did I have another prophecy to hear? "It would seem, that belief has been, held in error." said Chiron. Wait. What? Did he just say... I have a sibling? "What? I have a- there's another half-blood?" I asked.

"Not exactly. Technically Tyson is not a half-blood. Half-bloods are half-human. Hence the name." said Chiron. Now this guy just had me confused. If he wasn't half human... then what was he? "Um, then- then what um- what?" I said. Apparently my brain wasn't connected to my mouth at the moment. "Nymph. A sea nymph. And when you cross a deity with a sea nymph, you get a-" explained Chiron. As he was talking, I followed him into the Big House. I had a brother. It was weird. A brother that was a...

We walked in and found that Mr. D was trying to keep Tyson away from his wine collection. "Don't touch. it's a Gewurztraminer." said Mr. D. This guy and wine. Then Tyson turned around and smiled at us. Yup. This confirmed everything. "Hi brother." he said.

Tyson was part cyclops.

I lied before.

Now this was going to be an interesting summer.

A/N: Yes, kinda short, but they will get longer. I hope. lol Well, how was chapter one? :)
