So when I wen't over my first chapter, I realized there were a lot of grammatical errors. Sorry about that. I wrote it about a year ago and didn realized how many mistakes it had.

This is the edited version. It's 2,000 times better than the previous version, and there are a lot of changes. I suggest you read it again it you read it before 8:34 P.M January 6 (East coast, US).

"Ha ha ha, sooo funny Thals." Percy said rolling his eyes, while Thalia was still laughing hysterically.

"Oh it so was. You just shot and-and it hit him even though he was behind you!" she held her stomach and bent over, trying to control the unstoppable amount of laughter spluttering out of her mouth in between each of her words. Her head started spinning slightly and her ribs hurt, but she could not stop laughing.

A giggle was heard behind them, "Alright I think you made enough fun of him. Give Seaweed Brain a break. It's not his fault he isn't good at archery. He's not the lieutenant of the hunters of Artemis."

"Oh come on Annie, don't be a killjoy. Plus he's not just not-good at it, he stinks at it!"

"Shut up pine cone face. At least I'm not sca-"

"Don't you dare continue that sentence!"

"Or what? What are you gonna do about it?"

Annabeth just sighed and headed over to her table at the Dining Pavilion, knowing what was coming. She was wise enough to not get involved in this. Percy escaped towards Half Blood Hill while his cousin ran after him yelling threats like 'I'm gonna kill you' and 'If you ever tell anyone about that I will hunt you down and torture you until you're wishing for death.' They both knew she didn't mean that and, of course, Percy would never spill her secret, but they were having way too much fun just chasing each other and throwing threats at the wind. Some campers turned to look at the teens running up a hill like wild animals and rolled their eyes sighed exasperatedly, while others smiled or laughed.

It's not every day the man-hating group of girls known as the Hunters of Artemis visit a place with so many males, and the two cousins wanted to take advantage of every second the hunters were here, even if the third person in their group wasn't present. Nico di Angelo couldn't make it to camp this weekend because of his Underworld duties, but that didn't mean Percy and Thalia couldn't spend time together.

They made it up the hill, past the border, past the tree that used to contain the soul of a dangerous daughter of Zeus, past the spot Percy fought the great half-man half-bull that hates children of the sea god with a passion, and past the spot Sally Jackson was taken to be held hostage for the lord of the dead before Thalia tackled her cousin, and because of gravity, they rolled down the hill. When they completed their trip and reached their destination-the lush green grass outside the crazy camp-they lay there, staring at the fluffy, white clouds covering the sky.

Percy and Thalia were still relaxing in the valley when they heard faint noises that sounded suspiciously like malicious growls. Being the curious duo they are, the son of Poseidon and the daughter of Zeus follow the sounds until they spot a hellhound yapping at something. Thalia pulled Percy to the side. "Distract the hound, I'll take it out," she said and took off when she saw her cousin's nod.

They took out their weapons and Percy, being the idiot he is yelled out, "Hey, did you aggravate a witch or nature?" He glance at Thalia to see her rolling her eyes and did what any sane person would do; he stuck his tongue out at her and charged the hell hound. The monster released one last growl before pouncing on the hero of Olympus, but just before it could shred him, Percy rolled out of the way and Thalia shot an arrow at the spot her cousin previously stood.

Monster dust covered the area, and a teenage boy rushed over to them, firing questions faster than bullet trains. "What's happening? What were those things? Who are you? What am I doing here? Where IS here? Why do you have we-"

"Woah kid, calm down. My names Percy and this is Pine Cone Face-oops, I mean Thalia, what about you?" Thalia nudged him in the stomach-hard.

Instead of introducing himself, the currently-unnamed boy glared at them. "Answer my questions!"

"Come with us and we'll explain everything," Thalia told him.

"Hey seaweed brain who's that?" Annabeth asked when she saw two of the children of the big three come into camp covered in monster dust, a scowling teen trailing behind them.

"My eyes! My poor, innocent eyes!" Thalia exclaimed and covered her eyes when she saw the two lovebirds make out.

"Oh my gods Thals, it was just a kiss." Annabeth rolled her eyes.

"This is a new camper who refuses to tell us his name," Percy said referring to his girlfriend's earlier question.

Annabeth frowns at the boy and he groans. "My name is Matt Thomson," he grumbles.

She smiled and offered to take the kid to Chiron. Percy grinned and thanked her before running off with Thalia.

It's been a week since Matt arrived at Camp Half Blood, and many of the campers like him.

When he first explained to the Chiron what had happened, he took the credit for killing the hell hound, but Thalia and Percy didn't bother to correct him since he was a newcomer. It was pretty hard to make a good first impression at camp because everyone else has training and know what they are doing.

He was claimed by Hermes the night he arrived and has gotten along great with his siblings. They all play pranks together, the Stolls even stole two wallets for his 'welcoming.' The only problem was that the attention caused him to turn into an egotistical jerk. The attention has become addicting to him. He needs it. He wants to be the leader of this camp, but obviously that can't happen while Percy Jackson is still present.

So, he created a plan worthy of the Athena cabin. A plan to get rid of the savior of Olympus, to get rid of Percy Jackson. Him being the son of the God of Thieves, he successfully snuck into the Athena Cabin and as quietly as he could, searched for Annabeth's Invisibility Cap. He found it beside her bunk and scurried out of the cabin as fast as his legs could carry him.

Now his master plan- Operation Ultimate Betrayal -could go into action.
