"Percy!" It was the first day of summer, he was going to camp next week, and he was meeting Annabeth at Central Park. She had gotten somebody's phone, called his Mom's work, and then she told him when and where to meet Annabeth. The reason for the rather long message relay system was that demigods and phones don't exactly mix too well. Making a call on a phone was like telling every monster in a fifty mile radius where you are and for a son of Poseidon it was especially bad for the whole phone thing.

"Hey Annabeth."

"Percy… I think you have a sister."

"What?!"

It was perfectly reasonable to for him to act this way because his father was Poseidon and he was one of the Big Three. Big Three Gods that is. Poseidon, Zeus, and Hades were the Big Three. They had made a pact after WWII. Their children were especially powerful and attracted monsters like no other. Percy had made them promise to break the pact last summer, but for him to have a sister? She would have had to been born during the pact and well… only two children had been born during it.

"She's in the grade below us."

"Why do you think she's my sister?"

"Why do you think who's his sister?" Percy paled as Annabeth gestured behind him.

"Hi, Kate."

"Hey, Annabeth so this is the ever popular Percy?" He turned around slowly. Her eyes were blue one minute, green the next, but then grey. He blinked and all three colors seemed to settle into place and mix together. She has about half a foot shorter then him with long dark hair. It wasn't quite black like his, but a really dark brown that was slightly reddish. She had a splattering of freckles across her nose and cheeks.

"Yes, this is Percy. Percy say hi to Kate." The blonde elbowed her boyfriend as Kate stuck out her hand.

"I'm Storm. Katherine Storm, but everyone calls me Kate."

"I'm Jackson. Percy Jackson." He echoed her introduction and reached forward to shake her hand. "How old are you exactly?"

"Fifteen. Why?" He turned back to Annabeth.

"Annabeth she's fifteen. She should've been claimed already."

"Claimed?"

"Just tell him what you told me."

"Um, I have ADHD and dyslexia?"

"And I gave her one of my architecture books. She was to the tenth page before she realized it was in a different language and that she could read it anyways."

"What the Ancient Greek thing?"

"That doesn't make her a half-blood and it certainly doesn't make her my sister?"

"Half-blood? Your sister?"

"Percy, please just lis-"

"Hold up!" Annabeth turned her grey eyes from Percy to Kate. "Annabeth, you better start explaining things. What's a half-blood? What does ADHD and dyslexia have anything to do with anything? What do you think I'm his sister and why is he looking at me like I'm a ghost or something?" Percy blinked.

"You don't look anything like a ghost." Kate seemed a bit taken aback by this. Then they were interrupted by a giant shadow pacing over the sun.

"Kate!" A girl started running towards her. She was wearing a hat, her jeans were loose, and she run strangely. More like galloping than running.

"Cha-" Kate began to greet her friend but was interrupted by a giant… something or other. Her friend was plucked from the sky and disappeared.

"Was that her protector?"

"Yeah. I'm pretty sure that was."

"Crap." Percy took a ball point pen out of his pocket.

"What are you going to do? Write on… or stab it. Stabbing it with a glowing sword works too. Just too clarify, I'm not the only one who sees the dragon who just ate Charlotte right?"

"No, Kate unfortunately you're not." Annabeth pulled a knife out of nowhere. "Get behind me and Percy. We'll fill you in on the way to camp."

"Camp?" Kate didn't exactly move.

"Later!" Fire rained down on the trio and all talk ceased. Percy dove to the left, Annabeth to the right, and Kate went straight forward.

"Of course it breathes fire. It wouldn't be a friggin DRAGON if it didn't!" Kate grumbled as she ran underneath the giant beast.

"Kate move!"

"I just did!"

"Well move again! It's after you!" Percy yelled at the her as he tried and succeeded in distracting the dragon. It swooped low and he prayed to several gods that Annabeth had been able to jump on it.

"Why is it after me?"

"Because-" Annabeth appeared on top of the dragon on plunged her knife hilt deep into his scales, "You are a half-blood." She fell through the air and Percy caught her. "Believe me now Seaweed Brain?"

"Just because she's a half-blood doesn't mean she's my sister."

"What are you guys talking about? And why does nobody seem to care that my friend just got eaten by something that shouldn't exist?!"

"Come on. We need to get you to camp."

oOo

"Percy! Annabeth! You're back!" Two boys who looked as similar as twins ran up to the couple.

"Travis. Connor. Where's Chiron?"

"At the big house with Mr. D I think. Who's she?"

"Storm. Kate Storm."

"Daughter of?"

"What?"

"Who's your godly parent?"

"Um…"

"We've got to go. Bye Travis. Bye Connor."

"Bye." They said in unison and ran back down the hill towards camp.

"What did they mean?" Her eyes weren't exactly dry. She wasn't crying yet but she couldn't take much more. She had just watched her friend get eaten by something that only exists in books, been dragged in silence towards some mysterious camp, not been told anything she had been told she'd be told, and… it was all just a bit much. Charlotte had been her only friend for much of the school year. Annabeth and her had bonded over an architecture project near the end of the year, but Charlotte had been there. She hadn't really had much of a friend before then. She had lived in New York her whole life, but her parents transferred her to a different school every year. They had never told her why, and now Charlotte was gone.

"They meant that one of your parents isn't really your parent."

"She lives with both?" Kate looked up.

"What? Either my Dad isn't really my Dad or my Mom isn't really my Mom?"

"Sorry but it's the truth."

"No."

"You couldn't have come into the camp without being a half-blood and being a half-blood means one of your parents isn't your parent. Most of us only live with either our Mom or our Dad. Depending on who's the mortal. I've never met anyone with both their Mom and Dad."

"You're lying."

"No, we're not Kate." Percy tried to tell her gently.

"No!" Annabeth tried to reach out a put her hand on her shoulder gently but Kate broke away and started running. She didn't know to where, she could barely hear Annabeth and Percy calling out to her. They were probably running after her, but she had always been faster than Annabeth, besides she had a headstart. Suddenly she found herself on the deck of big ranch house. It was painted blue and there was a short, round man with a tiger striped shirt, red cheeks and curly hair sitting at a table playing cards with a horse. No… he wasn't a horse. Just most of him was a horse. A white stallion in fact. Where the neck should've been there was the start of a man's torso. She looked up at his face. He had kind eyes and curly brown hair.

"Who are you?" The short man looked at her in suspicion and irritation. She sniffled and crumpled to the floor and put her head in her hands. She wouldn't cry. She wouldn't.

"My dear!" She heard hooves clip-clopping towards her. She felt a warm hand on her shoulder. "Are you alright?" She shook her head as what must've been Percy and Annabeth made it to the porch.

"Annabeth. Percy. Do you have anything to do with this?"

"Chiron… she's… the one… I told you… about." Annabeth gasped out.

"The one with both parents?" There must have been a nod. "The rather powerful one with both parents?" Again a nod must have been given. "My dear, please, come with me." She raised her head and saw that the man/horse whom Annabeth had called Chrion was bending down and stretching his hand towards her. She took it, and he led her into the house and towards a whole new reality.

Sooo? What you think? R&R (This isn't it you know)
