Prologue

Matt Freeman was standing next to a pine tree with a golden fleece hanging from it. He was on top of a hill, several unique cabins were behind him. In front of him, he saw strange monsters he had never seen before. They were running towards him, growling and roaring. There was a beast that may have been a dragon preparing to battle with the monsters. Matt noticed a boy with dark hair and sea green eyes standing in front of one of the cabins.

"What? How did they get here!?" He shouted. He took out a ball point pen and un capped it. It grew into a three feet sword, made of bronze, Matt guessed. A monster with only one eye caught Matt by suprise and lashed out with its huge hand.

Matt sat up. It had only been a dream, which he had gotten used to as he had strange dreams most of the time. He immediatly noticed that he was in a room that was pitch black. He heard breathing. Matt was not alone. Before he could say something, the person spoke.

"Matt? Are you awake?" It was Lohan.

"Yeah," he replied. "Where are we?"

"I don't know," Lohan said. "I woke up only a few minutes before you did. There has to be a way out of here, help me look for a door knob."

Matt put his hands on the ground. It was wood, so that must have meant they were inside some kind of building, hopefully not another person's house. Matt got to his feet and began running his hands along the wall. He continued to do so until his hand hand felt somethng, it was a door knob. He turned it, relived to find out it was not locked. But when he pushed against it, it didn't open.

"I think there's something on the other side of it," Matt said. "Could you give me a hand?"

He heard Lohan walk over to where he was. They began to push. They heard something crash on the other side, and then it opened. It led to a room that had windows, which let sunlight stream into the room so they could see. Matt saw that a large shelf had been blocking the door. They looked into the room they had just come out of. It was empty except for the door with the five pointed star they had undoubtfuly come out of. They walked into the room. There were weapons and armor everywhere. There was a zombie like skeleton in the room with them. Lohan made a face.

"How disturbing," he said.

"What is this place?" Matt asked. It looked to him that they were in an attic of some sort.

Lohan shrugged. "Let us see if we can find any information,"

They found some stairs and exited the attic.

A few miles away, Percy Jackson was just waking up from a very pleasant sleep. He looked over at his digital clock. It read 10:30 AM. He got out of bed and went into the living room of his mom's apartment. Sally, his mother, and Paul Blofis, his stepdad must have still been asleep. He looked at the plant Calypso had given him, which was still growing in the winow sill. It had been three months since he had defeated the Titan Lord Kronos. Ever since then, his life had become pretty normal, as far as being a demigod went. He didn't mind though. His life had been filled with danger before he had beaten Kronos, so he was glad he could finally relax after four years of worrying about having to risk his life to save Olympus. He had not heard anything from camp since he had last been there three months ago, which was a good sign, as that meant that there wasn't any danger. He heard a sound come from his cell phone, which his mother had given him for his sixtheenth birthday. He walked back into his room and retrieved it from his bedside table. His girlfriend, Annabeth Chase had sent him a text message. The message read: Hey, u up? Percy typed out a respone.

Yeah, i am. wats up? A few seconds later, his phone started ringing. Percy knew Annabeth would start another long boring talk about architecture. He was now wishing he hadn't replied to the message. He hit the answer button, and brought the phone up to his ear.

"Hello?" Percy said.

"Hey, Percy," Came Annabeth's somewhat worried replied.

"Is something wrong? You don't sound too good."

"Yeah, there is actually. Have you heard about what happened in Hong Kong?"

"Uh, no, I don't really watch the news, it's kinda boring to me."

Percy could picture Annabeth rolling her stormy gray eyes at him this very moment.

"Well, Hong Kong was totally destroyed by a huge storm. But I don't think it was of natural causes."

"What? Do you think the gods have something to do with this?"

"I don't know, but I'm going to ask my mother about it. I'll talk to you later Percy, bye."

She hung up. Percy stared at the phone for a minute, then set it back down on his bedside table. He went back into the living room and turned on the TV.

The stairs led to another room. In it were two people. There was a man with curly brown hair in a leopard skin jogging suit and purple running shoes sitting at a table drinking a Diet Coke and reading a newspaper. There was a man in a wheelchair watching highlights of an American football game that was on the night before. They had not yet noticed Matt and Lohan.

Lohan put his hand on Matt's shoulder and whispered into his ear. "I will catch up with you later, see if these people will tell us where we are."

Before Matt could respond, Lohan used his stealth skills to silently exit the building without the two men noticing. Matt took a deep, silent breath, and then spoke.

"Hey," he blurted out.

Both men turned around at the same exact moment.

"What in the...how in the gods name did you get up there?" Leopard skin asked. "I wish you half-bloods would quit it with your pranks, they are really not that funny."

Pranks? Matt thought. And what in the world is a half-blood?

"This isn't a prank," Matt said calmly. "As crazy as it might sound, I was teleported here."

Leopard skin didn't act suprised. "Well teleporting is nothing special here kid, we do that stuff all the time."

Matt just stared at him in bewilderment. "Who are you?"

The man stood up. "I am Dionysus, god of wine."

Matt just stood there. This guy was out of his mind. "Yeah well prove it."

Dionysus snapped his fingers. Huge grape vines shot up from the ground. They came hurtling towards Matt. He concentrated on the vines and used his power to stop the vines in their tracks and tangle them up. They fell to the ground.

"It seems that we have another one on our hands," the man in the wheel chair said. He rolled over to Matt and observed him. "What is your name?"

"Matt," Matt replied.

"We are going to need your last name as well Matt," The man said.

Matt sighed. "My name is Matt Freeman."

The man nodded. "I am Chiron, the activitys director at this camp."

"Can you tell me where I am?"

"You are at Camp Half-Blood. If you are here, that must mean you are a half-blood."

"What is a half-blood?"

"A half-blood is a child who is half human, half god. Do you know who your god parent is?"

Matt might have gone crazy if he was just a normal boy, but he was a Gatekeeper. He had gotten used to the fact that crazy and sinister things found in movies were turning out to be real.

"What gods?" Matt asked.

"The greek gods, my boy. They are still here today, living in secret from mortals," Chiron replied.

There was no way Matt could have been a half-blood. Both of his parents had been mortal, he remembered that much. As far as he knew, Kate and Mark Freeman had been totally mortal.

"No," Matt said. "You're wrong. Both of my parents died in a car crash. There had been nothing god-like about them."

Chiron and Dionysus exchanged confused looks.

"Then how would you be able to get here? Mortals are not allowed to come into ths camp."

Matt pointed up stairs. "The room that was sealed off. I came through the door with the star on it."

Chiron closed his eyes and sighed. "I had heard about you, but I thought it was just a myth. If you came through that door, then you must be a Gatekeeper."

Matt nodded. "Do you know of the Old Ones?"

Chiron nodded. "Yes, I'm afraid I do Matt. It may seem we have another crisis on our hands."

"Hold on horse boy," Dionysus cut in. "If he's mortal, then how is he able to enter this camp?"

"He is just as strong if not stronger than a half-blood. He can also see through the mist, if he tries hard enough."

"What are you going to do with me?" Matt asked.

"I guess you may stay here a while. The Old Ones will not be able to get to you from here."

Matt nodded. Hopefully he would not be here long. He needed to find the other Gatekeepers before it was too late.

"In the mean time, I am going to call some other demigods. We must have more reinforcements here just in case the Old Ones find you."

Percy was sitting in front of the TV watching sports center. The sports announcers were talking about a Knicks/Lakers game that was on the night before.

"Percy, over here," he heard someone say.

He nearly jumped out of skin when he saw the Iris message sitting next to the TV. It was Chiron. He was in the Poseidon cabin with Dionysus and a tall, muscular boy.

"I take it you're not calling just to say hi," Percy grumbled.

"I'm afraid not. You need to get to camp as soon as possible. A new threat has arrived," Chiron said.

Sally walked in at that moment and immediatly noticed the Iris Message. She heaved a big sigh.

"Well, I guess I won't be having a relaxing morning after all," she said.
