Chapter 1: The Lighting Theif Part 1

I walked out of my cabin which I was claimed by Apollo and headed down the row. Outside of Hermes cabin, I could hear lots of laughter, followed with Percy and Annabeth coming out of the cabin. They walked a few feet away from the cabin and stopped, so it wasn't hard for me to follow them.

"Jackon, you have to do better than that."

"What?"

She rolled her eyes and mumbled something that I couldn't hear.

"What's your problem, all I know is I killed some bull guy-"

"Don't talk like that! Do you know how many kids at this camp wish they had your chance?"

"To get killed?"

"To fight the Minotaur! What do you think we train for?"

Percy shook his head,

"Look, if the thing I fought really was the Minotaur, the same one in the stories ..."

"Yes."

"Then there's only one."

"Yes."

"And he died, like, a gajillion years ago, right? Theseus killed him in the labyrinth. So ..."

"Monsters don't die, Percy. They can be killed. But they don't die."

"Oh, thanks. That clears it up."

"They don't have souls, like you and me. You can dispel them for a while, maybe even for a whole lifetime if you're lucky. But they are primal forces. Chiron calls them arche-types. Eventually, they re- form."

He had a thoughtful look on his face.

"You mean if I killed one, accidentally, with a sword-"

"The Fur ... I mean, your math teacher. That's right. She's still out there. You just made her very, very mad."

"How did you know about Mrs. Dodds?"

"You talk in your sleep." As creepy as that sounds, even I know that.

"You almost called her something. A Fury? They're Hades' torturers, right?"

Annabeth glanced nervously at the ground as if she expected it to open up and swallow her. "You shouldn't call them by name, even here. We call them the Kindly Ones if we have to speak of them at all."

"Look, is there anything we can say without it thunder-ing? Why do I have to stay in cabin eleven, anyway? Why is everybody so crowded together? There are plenty of empty bunks right over there." Why is he such an idiot?

"You don't just choose a cabin, Percy. It depends on who your parents are. Or ... your parent." Annabeth said looking pale.

She stared at him for a little bit.

"My mom is Sally Jackson," he said. "She works at the candy store in Grand Central Station. At least, she used to."

"I'm sorry about your mom, Percy. But that's not what I mean. I'm talking about your other parent. Your dad."

"He's dead. I never knew him."

Your father's not dead, Percy."

"How can you say that? You know him?"

"No, of course not."

"Then how can you say-"

"Because I know you. You wouldn't be here if you weren't one of us."

"You don't know anything about me."

"No?" She raised an eyebrow. "I bet you moved around from school to school. I bet you were kicked out of a lot of them."

"How-"

"Diagnosed with dyslexia. Probably ADHD, too."

What does that have to do with anything?"

"Taken together, it's almost a sure sign. The letters float off the page when you read, right? That's because your mind is hardwired for ancient Greek. And the ADHD-you're impulsive, can't sit still in the classroom. That's your battlefield reflexes. In a real fight, they'd keep you alive. As for the attention problems, that's because you see too much, Percy, not too little. Your senses are better than regular mortals. Of course, the teachers want you medicated. Most of them are monsters. They don't want you seeing them for what they are."

"You sound like ... you went through the same thing?"

"Most of the kids here did. If you weren't like us, you couldn't have survived the Minotaur, much less the ambrosia and nectar."

"Ambrosia and nectar?"

"The food and drink we were giving you to make you better. That stuff would've killed a normal kid. It would've turned your blood to fire and your bones to sand and you'd be dead. Face it. You're a half- blood." I really hope that he is going to except this. If he doesn't he really is an idiot.

"Well! A newbie!" I knew that voice and I started to walk over.

"Clarisse, why don't you go polish your spear or something?" Annabeth asked her. I know that they don't get along well.

"Sure, Miss Princess, so I can run you through with it Friday night."

"Erre es karakas!" I yelled at her. Percy and Annabeth looked surprised. I don't think they knew that I was there.

"We'll pulverize you, meet Clarisse, Daughter of Ares." Annabeth introduced him.

"Like ... the war god?" He asked.

"You got a problem with that?" Clarisse sneered.

"No, it explains the bad smell."

"We got an initiation ceremony for newbies, Prissy." She growled, she obviously isn't happy.

"Percy."

"Whatever. Come on, I'll show you."

"Clarisse-" Annabeth cut in.

"Stay out of it, wise girl." Annabeth did look a little pained, but I guess she's used to it or something.

Percy handed her the Minotaur horn and looked like he was ready to get punched in the gut. Clarisse, on the other hand, didn't want to fight.

She took him by the neck and dragged him to the girl's bathroom, and Percy was kicking and fighting the whole way there. I kinda feel bad for him. I hope he'll be okay.

"Like he's 'Big Three' material, yeah, right. Minotaur probably fell over laughing, he was so stupid looking." Her friends were laughing even more than before, while I was standing next to Annabeth, who has her head in her hands while watching through her fingers.

Clarisse started to put his head into the toilet, which is so gross, Percy is doing a good job trying to stay out of it.

The next thing I know is that the pipes are making a weird noise, and then water exploded out of the toilet and hit Clarisse right in the face. Soon enough, the whole bathroom's piping was tost. Everything was wet, Clarisse and her friends shoved Annabeth and I right out of the way and ran away. As soon as they were gone, the water stopped. And there stood Percy, whom you would expect to be soaking wet, but he and a circle around him was all dry. "How did you ..."

"I don't know."

We then walked outside, only to see the funniest thing that I've ever seen. Clarisse and her friends sprawled in the mud.

"You are dead, new boy. You are totally dead."

"You want to gargle with toilet water again, Clarisse? Close your mouth." I started to laugh so hard, what made it worse for me was that Clarisse's friends had to hold her back when she started to try to attack him.

Annabeth was starring at Percy, I have no idea what is going through her head, she is the daughter of Athena. No one would ever know what they are thinking.

"What?" He demanded. "What are you thinking?"

"I'm thinking," she said, "that I want you on my team to capture the flag."

Annabeth agreed to show Percy around so I could go and change. I told her that once I was done I would take over for her, but she disagreed, saying that I haven't been around long enough.

Lee led us all to the mess hall, I saw Annabeth leading her cabin and Luke leading Percy's cabin. They are kind the only people that I really know, not including my half-siblings. At the front table, there was Mr. D, Chiron, Grover, and a few other Satyrs.

We were lead to our table, when we got there, Chiron stomped his hoof to silence everyone, then raised his glass and said: "To the Gods!" Like he does every night, then the campers repeated it.

Wood nymphs came forward with platters of food: grapes, apples, strawberries, cheese, fresh bread, and, barbecue. Not my favorite meal, but it is still good.

"Cherry Sprite," I ordered it in my glass.

We loaded our plates and got up to serve some of our meal to the gods, as I learned that we did at every single meal. I put in my grapes, all of them are ripe, so I thought that Apollo might like them.

"To Apollo," I spoke.

We got back to our seats and talked about our day at camp, most of them involved plants. Soon enough Chiron stomped his foot to make us pay attention.

"Yes, I suppose I'd better say hello to all you brats. Well, hello. Our activities director, Chiron, says the next capture the flag is Friday. Cabin five presently holds the laurels." Mr. D said with a sigh. Followed with a bunch of cheering from Ares's kids. "Personally, I couldn't care less, but congratulations. Also, I should tell you that we have a new camper today. Peter Johnson." Chiron then murmured in his ear. "Er, Percy Jackson, That's right. Hurrah, and all that. Now run along to your silly campfire. Go on."

Everyone started to cheer and we all headed down to the amphitheater. I love the campfire, we sing songs about the Gods, eat s' mores (one of my favorites!), and joke around. It really feels like a family.

When the campfire ended, we all headed back to our cabins and went to bed. I have to admit, while I am worried about what Harry is thinking, I've never been happier than I am now.

Each day at camp was following a routine. It wasn't boring though. It was always fun. Will helped me with everything, so did Lee. They are kinda the co-leaders of our cabin, I take Ancient Greek, which is fairly easy, I thought that it would be so much harder to do though, but it was so nice to understand something. Due to my ADHD, I can't really stay still, according to Chiron they are battle reflexes.

Then throughout the day, I will be doing outdoor activities. Archery is really fun, I almost got a bullseye on the first day. Foot racing is okay, I am okay at it, but they wood-nymph beat everyone, but they have been running for who knows how many years. I am terrible at wrestling, I am basically skin and bone, there is nothing really good that I can do, besides bruising them with my elbows. I am also a year younger than a lot of them, they said that campers are usually here at the age of twelve or thirteen, I'm ten almost eleven I only have four more days.

I spent some time with Percy and Annabeth, they are my best friends here, Annabeth has been trying her best to teach Percy Ancient Greek, but according to her, he is kinda stupid. I don't really know what to think though.

Today though, it's Percy's sword-fighting lesson.

"Good luck," one of the campers told me. "Luke's the best swordsman in the last three hundred years."

"Maybe he'll go easy on me," I said.

By the time that Luke called for a break, my partner was

lying on the ground in pain. I only bruised him, I'm the one who actually go cut. I have a scratch on my arm, which hurts.

As soon as the break was over, we watched as Luke decided that Percy would be his little demonstration toy. Only that Percy beat him. When they went again, Luke beat Percy, so I'm wondering what the heck was going on.

Today is Friday, July 14th, my birthday. It's cool, I never told anyone my birthday, thankfully, so no one told me happy birthday.

Back home, Harry would always come into my room and yell in my face "HAPPY BIRTHDAY!" Which gets annoying after a few years.

It's in the afternoon, and I'm spending by being with Percy and Grover at the lake. Earlier I was on the climbing wall, which is now one of my favorite things here. It's where if you don't climb up fast enough, you get lava poured down on you, it's so cool.

"How was your conversation with Mr. D?" Percy asked Grover, in response Grover's face started to turn a sickly shade of yellow. I believe that he might throw up.

"Fine," he said. "Just great."

"So your career's still on track?"

He glanced at him nervously. "Chiron t-told you I want a searcher's license?"

"Well... no. He just said you had big plans, you know ... and that you needed credit for completing a keeper's assignment. So did you get it?"

"Mr. D suspended judgment. He said I hadn't failed or succeeded with you yet, so our fates were still tied together. If you got a quest and I went along to protect you, and we both came back alive, then maybe he'd consider the job complete." He said looking down.

"Well, that's not so bad, right?"

"Blaa-ha-ha! He might as well have transferred me to stable-cleaning duty. The chances of you getting a quest... and even if you did, why would you want me along?"

"Of course I'd want you along!"

Grover stared glumly into the water. "Basket-weaving ... It must be nice to have a useful skill."

"Grover, I bet that you have may talents, even though I don't know you that well." I tried to assure him.

I zoned out while Percy and Grover had their own little conversation, that is until Percy asked about the four empty cabins.

"Number eight, the silver one, belongs to Artemis," he said. "She vowed to be a maiden forever. So of course, no kids. The cabin is, you know, honorary. If she didn't have one, she'd be mad."

"Yeah, okay. But the other three, the ones at the end. Are those the Big Three?"

Grover tensed. We were getting close to a touchy subject.

"No. One of them, number two, is Hera's," he said. "That's another honorary thing. She's the goddess of marriage, so of course, she wouldn't go around having affairs with mortals. That's her husband's job. When we say the Big Three, we mean the three powerful brothers, the sons of Kronos."

"Zeus, Poseidon, Hades."

"Right. You know. After the great battle with the Titans, they took over the world from their dad and drew lots to decide who got what."

"Zeus got the sky," I remembered. "Poseidon the sea, Hades the Underworld."

"Uh-huh."

"But Hades doesn't have a cabin here."

"No. He doesn't have a throne on Olympus, either. He sort of does his own thing down in the Underworld. If he did have a cabin here ..." Grover shuddered. "Well, it wouldn't be pleasant. Let's leave it at that."

"But Zeus and Poseidon-they both had, like, a bazillion kids in the myths. Why are their cabins empty?"

"About sixty years ago, after World War II, the Big Three agreed they wouldn't sire any more heroes. Their children were just too powerful. They were affecting the course of human events too much, causing too much carnage. World War II, you know, that was basically a fight between the sons of Zeus and Poseidon on one side and the sons of Hades on the other. The winning side, Zeus and Poseidon, made Hades swear an oath with them: no more affairs with mortal women. They all swore on the River Styx."

Thunder boomed.

"That's the most serious oath you can make."

Grover nodded.

"And the brothers kept their word-no kids?"

Grover's face darkened. "Seventeen years ago, Zeus fell off the wagon. There was this TV starlet with a big fluffy eighties hairdo-he just couldn't help himself. When their child was born, a little girl named Thalia ... well, the River Styx is serious about promises. Zeus himself got off easy because he's immortal, but he brought a terrible fate on his daughter."

"But that isn't fair.' It wasn't the little girl's fault."

Grover hesitated. "Percy, children of the Big Three have powers greater than other half-bloods. They have a strong aura, a scent that attracts monsters. When Hades found out about the girl, he wasn't too happy about Zeus breaking his oath. Hades let the worst monsters out of Tartarus to torment Thalia. A satyr was assigned to be her keeper when she was twelve, but there was nothing he could do. He tried to escort her here with a couple of other half-bloods she'd befriended. They almost made it. They got all the way to the top of that hill. All three Kindly Ones were after them, along with a horde of hellhounds. They were about to be overrun when Thalia told her satyr to take the other two half-bloods to safety while she held off the monsters. She was wounded and tired, and she didn't want to live like a hunted animal. The satyr didn't want to leave her, but he couldn't change her mind, and he had to protect the others. So Thalia made her final stand alone, at the top of that hill. As she died, Zeus took pity on her. He turned her into that pine tree. Her spirit still helps protect the borders of the valley. That's why the hill is called Half-Blood Hill." Grover explained.

"Grover, have heroes really gone on quests to the Underworld?"

"Sometimes," he said. "Orpheus. Hercules. Houdini."

"And have they ever returned somebody from the dead?"

"No. Never. Orpheus came close... Percy, you're not seriously thinking-"

"No, I was just wondering. So ... a satyr is always assigned to guard a demigod?"

"Not always. We go undercover to a lot of schools. We try to sniff out the half-bloods who have the makings of great heroes. If we find one with a very strong aura, like a child of the Big Three, we alert Chiron. He tries to keep an eye on them since they could cause really huge problems."

"And you found me. Chiron said you thought I might be something special."

"I didn't... Oh, listen, don't think like that. If you were-you know-you'd never ever be allowed a quest, and I'd never get my license. You're probably a child of Hermes. Or maybe even one of the minor gods, like Nemesis, the god of revenge. Don't worry, okay?" He sounds like he's assuring himself.

After dinner, it was time for capture the flags. Annabeth and two of her siblings ran in with a grey silk banner that had a barn owl above an olive tree, while Clarisse and two of her siblings ran up with the same kind of banner, but red with a spear and a boars head.

The teams were announced.

Athena

Apollo

Hermes

Other team

Ares

Dionysus

Demeter,

Aphrodite

Hephaestus

"Di immortals!" Annabeth said. "That's a hellhound from the Fields of Punishment. They don't ... they're not supposed to ..."

"Someone summoned it," Chiron said. "Someone inside the camp."

Luke came over, our banner in his hand forgotten.

Clarisse yelled, "It's all Percy's fault! Percy summoned it!"

"Be quiet, child," Chiron told her.

We watched the body of the hellhound melt into shadow, soaking into the ground until it disappeared.

"You're wounded," Annabeth told me. "Quick, Percy, get in the water."

"I'm okay."

"No, you're not," she said. "Chiron, watch this."

Percy stepped into the water and his chest started to heal. A lot of people gasped to this, including me. Then I noticed something above his head, a glowing trident.

"Your father," Annabeth murmured. "This is really not good."

"It is determined," Chiron announced.

"My father?"

"Poseidon," said Chiron. "Earthshaker, Stormbringer, Father of Horses. Hail, Perseus Jackson, Son of the Sea God."
