Author's Note: This is my first fanfic ever, so please don't criticize too harshly. I am a person and I do have feelings I would appreciate it if you would mind them. And on that happy note I will now get to the synapse of the story. By the way, in this story The Percy Jackson Characters are one year older than the Harry Potter Characters, so when Percy first goes to Camp Half-Blood, Harry will just be going to Hogwarts. Also I have not read the Blood of Olympus yet, so please do NOT tell me anything about it yet. I hate it when people ruin stories or movies or anything really, like that. This story will either be a Percy/Hermione or Percy/Annabeth story, depending on how who you guys vote for. I will let you know when to vote (Just leave it in a review) when the time for Percy's decision is to be made but until then it will go as a Percy/Hermione story. If you guys have any questions about the story please leave a review and I will be happy to answer them. I will try to update at least once a week, but if I can't then you will see at least two or three chapters posted at once. Hope you guys enjoy the story.

Disclaimer: I'm only going to do this once so, I don't own PJO/HoO or HP. They are owned by the amazing Uncle Rick and J.K. Rowling. I only own the plot and the OCs.

Chapter 1

Percy's P.o.V

It has been four months since the defeat of Gaia. Everyone is doing just fine. Frank is the new praetor of Camp Jupiter, along with Reyna. Hazel is also at Camp Jupiter to help support Frank when he needs it. Jason the new cabin leader of the Zeus cabin, here at Camp Half-Blood. Piper is still the cabin leader of the Aphrodite cabin and is still dating Jason. Leo is somewhere out at sea, looking for Calypso's island. Poor guy. The Gods could have at least given him some sort of GPS or even better, they could have taken the time to actually go and get her and bring her here instead of making Leo go out, risking his life to find her. Nico is, well, I'm not really sure what's wrong with Nico. I can tell he is struggling with something, but I'm not sure how to help him. I'm kind of starting to think it has to do with me. I mean every time I try to talk to the guy he runs away. I don't smell that bad do I? Then there's Annabeth and I. Although things are a lot better now than what they were in the past, we still have a lot to work out. Especially regarding our nightmares. When they first started, they were terrible. It would always be either I woke the camp up, screaming Annabeth's name at the top of my lungs to get away from the cliff, or it was Annabeth screaming my name and wondering where I've gone and why I left her alone, down there in that terrible black pit. Eventually they got better, thanks to Chiron telling us that it was okay for her to stay in my cabin at night…as long as there was no "funny business" going on between us. And nothing extremely intimate was done during the night. It was mainly comforting hugs and sweet, reassuring kisses to help calm the other down. Okay so we made out on my bed a couple of times, but it's not like we went any farther than that. Now our nightmares are almost nonexistent, but there are still a few rare occasions where they come up. Everything was finally starting to settle down at both camps. That is until Chiron sent me on a quest to retrieve a stranded demigod from New Jersey. The trip up there was quiet and peaceful, but I had a really bad feeling that something was going to go terribly wrong. When I reached the demigod's school, I was less than enthusiastic to see my favorite monster attacking the demigod. The Minotaur roared loudly, sending spit spraying everywhere out of his mouth. Not to mention his breath smelled like sewage. Okay one gross, and two has he ever heard of this cool thing called toothpaste. The Minotaur spotted me and charged. I un-capped Riptide and swept in a deadly arc upwards across the Minotaur's torso sending it crumpling into a cloud of dust back to Tartarus. The boy was a little shaken and definitely scared, but he seemed to be fine. He had black hair, kind of like mine, and dark green eyes. He was skinny and slightly pale, though that may be from what he just experienced. I told him I knew of a place where he could be safe and would be able to train in peace. He had all sorts of questions about who he was, what that thing was, how my pen had turned into a sword. And I answered to the best of my ability. I explained to him about the gods and goddesses. I told him about both camps and a few tips to surviving Camp Half-Blood like not pissing off Clarisse and her siblings. The more I talked to the guy the more I actually saw us becoming something close to friends. All too soon we came back to camp and I introduced everyone to the new camper Brad Wright. I was about to tell everyone how I had saved him when he butted in and said that HE had killed the Minotaur on his own and I had come just in time to watch him finish it off. Now I didn't mind in the slightest that he was taking credit for the kill, at least the Aphrodite Cabin will be off my back for tonight, though thanks to Piper the Aphrodite cabin is actually a little more bearable than it has been in the past. I went back to my cabin took a shower and jumped into bed, curled up next to my wise girl, and drifted off into a peaceful sleep. But little did I know, that that would be the last peaceful dream I would have for a while. The next day I was awoken by my beautiful wise girl telling me that there was a cabin councilor meeting in the Big House and we needed to go. You see, even though Annabeth lives in cabin three with me, she is still the cabin councilor of the Athena cabin. After getting dressed and stealing a searing kiss…..or two, from Annabeth, we headed, hand in hand, to the Big House. When we got there I was surprised to see that my father was there. He looked kind of frustrated and a little worried. I wonder why? When everyone was seated the meeting began.

"I have called everyone to this meeting to discuss the claiming of Mr. Brad Wright." Stated Chiron.

"Why are we talking about this rookie's claiming at a meeting? Why does it have to be done in front of us? You know I have better things to do than sit here and find out about this kid's parents. Seriously I could be giving some new camper the good old "welcome to camp" tour. Right Prissy" said Clarisse

"Yeah, right." I said.

"Actually, this kind of concerns you Percy. You see…..Brad is also my son." Confessed Poseidon.

The whole room fell silent. Everyone stared expectantly at Poseidon, Percy, and Brad, waiting for one of them to speak.

"I have another brother?" I asked turning to look Brad in the eyes.

Now that I can actually get a good look at him, he does kind of look like dad. Same black hair, same skin tone, hell they even have the same dimples. I wish I had dimples. Oh, wait! I do have dimples.

"Wow. Two children of Poseidon." Breathed Jason.

"Now considering that Percy now has a brother that will be staying on a regular basis, I am sorry to inform you, but Annabeth must move back to her original cabin. It is only fair." Said Chiron

"I understand Chiron. It's no problem at all." Said Annabeth, but even I could see the disappointment and sadness in her eyes.

"No Chiron. It's okay for her to stay. I'll sleep in one of the guest bedrooms in the Big House. I would hate for them to separate because of me." Said Brad.

Even though the comment sounded sincere he had an almost evil look in his eyes as he said it. I guess this is when I first started to not trust my brother. And over the course of the next few weeks, it became clear his ulterior motives. Yes I know what that word means. It's what happens when your super, hot girlfriend is a freaking genius. His goal was to destroy me. It was simple at first. Start a few rumors and capture a few wrongly interpreted pictures to prove a point. Then he started to pull pranks on other campers and then blame it on me. I told my friends about what he was doing, but they all thought that he was some kind of saint or something. The only person who believed me was Annabeth, but as rumors started spreading, her friends and sibling started saying that I was no good and that she shouldn't trust me. I'm glad that at least she is on my side. It almost feels like she is the only one who still thinks highly of me. As for the rest of my friend, well they started to turn away from me, and to Brad. All he had to do was say something or pull a prank at the exact right time to pull it off that I did it. Eventually Annabeth was the only thing I had left. One morning she started acting strange. She was avoiding me and I didn't know why. I hadn't done anything….I think. That's when I started to realize that I was losing her too. I knew that I had to act fast before she left me for good. So I went to Mt. Olympus and asked for a meeting with her mother. (By myself I might add.) I knew what I needed to do, so I asked Athena the one question I had been dying to ask for a while now. She said that she did not believe the rumors she hears from the camp and will give me a chance to prove myself worthy by gaining an apple of immortality. If I do this task, without dying, then my request shall be granted. I traveled to Mt. Tam and stood before Ladon. He was a hard monster to beat. In fact, it almost killed me, but I prevailed. I traveled back to Mt. Olympus and confronted Athena. She was shocked that I had come back alive, but she congratulated me anyway. I stopped by Hephaestus's temple and asked him for an important favor. He agreed whole-heartedly and got to work. By the time he was finished it was almost sunset. I thanked him and was on my way back to camp. I was so happy, excited, and nervous all at the same time, yet I also felt like nothing could bring me down. When I finally arrived at camp, the air seemed more frigid than it had when I left the Empire State Building. I walked through the camp, searching for Annabeth and receiving nasty glares from all the campers. I guess Brad has been making up even more rumors about me. I had searched practically everywhere for her. She was just nowhere to be seen. So to clear my head, I went for a walk along the beach. As I was walking I saw a couple sitting on sand kissing. I could tell that the boy was Brad from the look of him, but I couldn't figure out who the woman was. I was just going to walk away and leave them be, that was if I hadn't heard what my brother had said.

"Come on! When are you going to break up with that idiotic brother of mine? I'm so much better than him."

What I heard next is what hurt me the most.

"Don't worry Brad. The next time I see him I'm going to tell him it's over." Said who I could clearly make out as Annabeth.

A million thoughts were running through my head. One, why would she do this to me. Two, how long has thing been going on. Three, how am I going to ask her if my heart feels like it's been ripped out of my chest, stomped on, and crushed into a million pieces. I didn't understand. What had I done wrong? What did I do to deserve fate as cruel as this? I didn't stop to think if they heard me or not, I just ran. I ran as fast as I could into my cabin. I slammed the door and sank against it. I sat there thinking about how I things could have been different. And for some reason, I thought of her. I thought of the girl I hadn't seen in forever that was still somehow my best friend. I didn't think, I just did. I walked over to the nightstand next to my bed and opened the drawer. After moving everything around I found the hole in the bottom. I stuck my finger through and pulled up on the secret compartment. Inside was a small silver chain with a two silver dog tags on it. One had a picture of a trident and H&P Best Friends Forever engraved on one dog tag. The other was engraved with the words you will never be alone. I hadn't worn the chain in years. Just looking at it brought back memories

It was a warm yet cloudy day at the New York National Airport. She was just telling me about how much she was looking forward this amazing school she had been accepted into….again. But I didn't care. She laughed so joyously, it was hard to believe that I wouldn't be seeing her for a long time. I wish I could've gone with her. We would have had so much fun in England. I was happy for her, really, but I didn't want to let her go. She's my best friend for crying out loud. We were standing by the security check-in. She was panicking because she thought she forgot something. I couldn't help but laugh. As we stood by the check-in, tears started to flood her eyes. She didn't want to leave me, but she also wanted to go to this once in a lifetime school. I reassured her she was making the right choice and she smiled. Then she pulled out a case from her bag and handed it to me. I opened it and was stunned. I turned to her and said

"You didn't have to do this. Not for me."

"But I wanted to. Look one says H&P Best Friends Forever, because you and I are best friends. Not even distance can tear us apart. And the other one says You are never alone, because I know that someday you are going to feel sad because no one is around to help you, but you can always find help with me. I'll always be there for you. No matter what." She said.

"Wow. Thanks. And you too. If you need someone to lean on, I'll be there, always. Then she gave me a big hug, gathered her things and flew away to a school in London for people like her. And I watched from the window even after the plane was out of my line of sight, because I didn't want to have to face the fact that I just lost my best friend in the whole wide world. I knew, from that day on, that I was never going to forget her. And I didn't.

It was then that I realized what I had to do. I tore off the Camp Half-Blood necklace that I had been wearing since I was twelve, and slipped the dog tags around my neck. I ran to my dresser drawer and yanked it open. I pulled out anything that belonged to me, making a pile of things that I would take with me, and a pile of things that were memorabilia from Camp Half-Blood. After packing everything into my backpack, I grabbed the pile of Camp Half-Blood clothes and threw them into the fire place. I then tossed my Camp Half-Blood necklace into the flames. The last thing to go into the fire, was the picture of the seven that was taken after the war. I had a care-free smile on my face and had my arms wrapped around Annabeth who was smiling and laughing with everyone else around us. At the time I thought I was surrounded by my friends, but now I realize that they were just using me because of my title among the gods. As soon as someone else came along that seemed to be better than me, every one of my so called friends, left and flocked to the new claimed "hero". I was definitely sad, mad, and really disappointed, but most of all, I felt betrayed. I mean the people that I care about most just up and left me. I couldn't just sit here and deal with it anymore. I needed someplace to go. Someplace that I could be safe, and with people that I can actually trust. I have a place in mind that might just be what I'm looking for, but I should check with my mother first. I don't want her to have to worry about another sudden disappearance act from me…..again. So I decided to tell my mother where I was going. But only so she wouldn't freak out about not knowing where I am…..again. I grabbed my bag and stuffed the thing Hephaestus gave me into my pocket before storming out of my cabin. As I left camp, I saw my father standing among a crowd of demigods, with Brad standing beside him. I could hear his voice, loud over the cheering demigods

"Let's hear a loud cheer for my brave, skillful, and personal favorite son Brad"

I could hear the other campers cheering and chanting his name, and when I looked back, I saw Annabeth, kissing him like there was no tomorrow. To think that she used to kiss me like that. To think that I was going to actually propose taking a VERY LARGE step in our relationship earlier today brings a wave of emotions crashing down on me. None of them good. That's when the first few tears slid from my cheeks. I couldn't take it anymore. I had to leave. I sprinted for the boarder. Once out, I wandered through the wilderness until I found the nearest highway, then followed it into the city. It wasn't long until I had hailed a taxi and was on my way to my mother's place. I wonder if it would be safe for me to stay just one more night there. What if no one even knows I left Camp? Would anyone even realize that I was gone? It seemed unlikely so I told myself I would only stay for a while then be on the go again. The closer we got to my mom and Paul's apartment complex the stronger the smell of smoke came. When we were only a few blocks away, I heard sirens blaring. Then I saw the clouds of smoke and prayed that it hadn't come from my parent's building, but of course I always have the rottenest of luck. By the time I had gotten to the building, all that was left were piles upon piles of ashes. I paid the driver and started searching the crowd for my mom or Paul, but I couldn't find them anywhere. I then started to ask around, wondering if anyone had seen them, but everyone said that they didn't. It wasn't until I asked a police officer that I found out what had happened to them. And since I did ask, I really wish that I hadn't.

"Look son. Now this may be hard for you to hear, but, your parents didn't make it out of the fire. We tried everything we could but we just couldn't get them out. I'm so sorry." He said rather sincerely.

I couldn't believe what I was hearing. I backed away slowly. Then took off running as fast as I possibly could. I had to get away. Far, far away from the building. Fresh tears started to spill down my face as I ran. I didn't even know where I was going. I was just running. Running as far away from the world I knew as I possibly could. Now with all my mixed thoughts and emotions, I kind of forgot to look where I was going and ended up running into and elderly man. As I slowly got up, I apologized dearly to the old man for knocking him over.

"Oh, it's quite all right boy." Said the man.

For an old man, he sure did look, well, regal. He was wearing a purple robe with silver decals on it. He looked very, majestic, for an old man. He had long white hair and a VERY long white beard with some sort of pony tail holder holding the bottom together.

"I'm really sorry for knocking you over sir. I promise I'll pay attention to where I'm going next time." I tried to say.

"Again, it's quite all right. I was just trying to navigate my way around this city. But, it appears that I have lost my way. Please, if you would, could you direct me in the direction of a um… Camp Half-Blood?" he asked.

"What for?"

"To keep it between you and me, I kind of need a little help." He said.

"What kind of help do you need?" I asked

"Well, I need someone to teach my students how to defend themselves in the events of an attack. So if you would be so kind as to give me direction as to where I could go, that would be wonderful." The man said.

"You won't find anything there." I said

"And why is that?" he asked

"Because, everyone there only cares about themselves. If you want someone from there to teach your students, then you will need to give them something in return. And it won't be something simple, I can assure you that." I said.

"And how do you know this, if you don't mind me asking?" asked the old man

"I used to attend the camp." I said with a guarded expression. "I grew tired of all their games and left to find some other calling." I said truthfully

"Well then, why don't you do it?" he asked

"Do what?"

"Teach at my school. I can only assume that you are good at fighting considering that you are outside the borders."

"I don't know. What exactly would I be getting myself into?"

"Well first of all, you would teach my students about who you are and others like you. You will also teach them how to fight and defend themselves. Now considering that you are illknowledged about us. You will also be a student at the school, learning our ways and customs."

"What do you mean you ways and customs?" I asked

"You see, I am the headmaster of a school called Hogwarts. Hogwarts is a school for young witches and wizards. You will be teaching them about you and they will be teaching you about them. I don't see how this won't work. So what do you say?"

Considering that I didn't have many other options, I decided to go with it. Plus I'm pretty sure that she said that the school she would be attending was called Hogwarts. Maybe I'll run into her there or even better. Teach one of her classes.

"You can count me in…um…sir?" I said a little confused.

"Oh silly me. Where are my manners? I'm Albus Dumbledore."

"Perseus Jackson sir. But you can call me Percy." I said while reaching out to shake his hand.

He shook it firmly and we continued to walk and talk back the direction that Dumbledore came. Things were finally starting to change for me. Hopefully for the better.
