So, I am a novice novelist and am working on writing my own novel, but I always thought it would be cool if my characters met the characters from Rick Riordan's Percy Jackson/Heroes of Olympus Universe. Of course I don't own anything except for the characters of Grant, Alice, Matt, David, and Dawn. So, here goes nothing.

It was a bright day in the state of Maine. On the east coast there was a large white house with the forest to its back and a large clearing to its front with a sudden drop off as the cliff met the ocean. Halfway between the house and the cliff edge was a small wooden bench. There on the bench sat Alice Millen, a girl of about 16 with long brown hair supported by a blue headband with a matching blue and white blouse. Alice took a deep breath, inhaling the salty ocean air.

This is the life, she thought as she leaned back and opened a crisp new book. Her nose filled with that hardcover book smell. She started reading the first few sentences before her relaxation was interrupted by loud yelling. Alice turned to look at the house. In one of the windows she could see two shadows arguing. One of the shadows grabbed the other by the shoulders and suddenly they both vanished.

At the same moment, Matt appeared at the edge of the cliff holding David by his ankle over the edge.

"Seriously, dude what did you do with my jacket?" questioned Matt. Out of the six of them at the house Matt was the most moody. It was understandable though, since he went through a lot of traumatic events in his life. Now he was the oldest in a group of super-powered outcasts living together in a house in Maine. Matt had the ability to teleport himself and anyone he had physical contact with along with absorption and manipulation of kinetic energy. Also, he was really strong ,having grown up alone on the streets. He was currently demonstrating that strength by dangling David over a 50 foot drop into the ocean.

"Matt, are you crazy?" Alice yelled at him. "Let him go!"

"Not until he gives me back my jacket."

"Sheesh, you and that jacket," said David. "You know I've never seen you take it off before and I've gotta say you're quite a well toned man. I mean the muscles are practically ripping that shirt right off your chest. I'm not gay, but those biceps are mesmerizing."

"David! Give Matt his jacket back," said Alice.

"Well you see... there's a problem with that." David was the most immature of the group. He was cocky, blatant, loud-mouthed, and annoying. He was, also, Alice's boyfriend for reasons beyond her understanding. David was one of the last few mages left in the world, the only other one being Alice. A mage is, as you would expect, someone who could use magic. "I kind of turned your jacket into a puppy."

"Why the hell would you do that?" asked Matt.

"Because I wanted to give Alice a gift for our two week anniversary."

"Aww," said Alice. "I don't like dogs that much, but thanks for the thought."

"Where is the puppy now?" asked Matt.

"Where you would expect a dog to be, in the doghouse. Please, let me go now. The blood is rushing to my head and I'm in excruciating pain."

Matt glanced back at Alice, who nods. Matt throws David back onto the grass. "Thank you, so much for showing me mercy." David groveled at Matt's feet. "I promise I won't waste this second chance, you've so graciously given me. You won't have reason to be mad at me ever again, I swear."

Alice pulled David to his feet. "You said the exact same thing yesterday."

"Well don't tell him that," responded David. Alice put her face in her palm.

"I would get his head checked out if I were you," Matt said to Alice. "I think he's got a few screws loose."

"Tell me something I don't know."

Matt teleported away to find his jacket/puppy leaving Alice alone with David on the cliff. She stares off the edge at the beautiful view of the ocean. She took David's hand in hers. "Did you really want to give me a puppy?" she asked.

"Of course, have I ever lied to you?" David quickly added, "Don't answer that!"

Alice smiled. She pulled David closer to her and put her head on his shoulder. David blushed. For the first time ever he was speechless. Alice didn't care, she wanted the silence to last forever. But it didn't.

Alice. Alice. Alice. Alice. She could hear the thoughts of her twin brother, Grant. They shared a sort of telepathy so they could communicate with each other over great distances with just a thought.

"What!?" she yelled out loud, startling David so he almost fell off the cliff. Alice, still holding David's hand, pulled him back.

What? Thought Alice.

I'm having some trouble talking to Dawn. She's freaking out about the future again. Could use some help if you're willing to offer it.

Alice sighed. I'm on my way. Keep her from hiding again or we'll never find her.

"Trouble with your brother?" asked David.

"Trouble with Dawn," responded Alice. Together they rushed back to the house.

Dawn is a nice girl. She actually lived in the 1600s until she was rescued by Grant and Alice on a weird time-traveling adventure. Dawn was accused of being a witch and was about to be burned at the stake. The villagers were frightened because Dawn could manipulate light to make herself invisible. Unfortunately, bringing her to the present has made her go into future-shock a few times. The group tries to introduce her to new things slowly, but sometimes it still proves to be overwhelming. Luckily, this wasn't one of those times.

Grant sat at the head of a large oak dinner table. Scattered across the table were pictures of people and folders with lots of documents in them. Alice and David came rushing in through the side door. Grant greeted them with a nod.

"Now, I bet you're all wondering why I called you here today," stated Grant in an entirely serious tone. He was seated at the opposite end of Alice and David with his hands together.

"Where's Dawn?" questioned Alice.

"She's probably making out with Matt upstairs, who knows? Those two have that thing where they're kind of together, but neither one wants to risk the friendship by admitting it."

"So, then yes, I am wondering why you called me here today," said Alice, scowling.

"Glad you asked," said Grant, who stood up and smiled. "I took the liberty of looking through some of ARC's unsolved case files." He pointed to the folders on the table.

"I'm going to assume you didn't have permission to take those files," said Alice, crossing her arms.

"You assume correctly, my dear sister, but that's beside the point. You know how there have been a few monster sightings where some people could see them and some couldn't, almost as if the monsters were shrouded in some way by a veil or something?" Grant slid an open folder across the table to David, who picked it up and flipped through the contents, nodding.

"Is this going somewhere?" asked Alice.

"In due time, yes it is. I cross referenced several of these cases where monsters seemed to disappear without any interference from ARC or us. It seems that several of these cases involves a select few individuals." Grant threw some photos on the table. One photo was of a scruffy teenage boy with dark hair and sea-green eyes. The other was a picture of a blonde girl who's stormy gray eyes seemed to frighten you even though you knew it was just a photo. They both wore orange T-shirts with the words "Camp Half-Blood" written on them.

"Notice the matching shirts," said Grant. "Whoever these two are, they leave destruction in their wake. Remember that incident in Seattle? That was them. I think that this 'Camp Half-Blood' is a breeding grounds for evil monsters and these kids unleash them upon the world."

"Okay, so you lied to me about Dawn having a panic attack so I'd come and listen to your crazy theories?" asked Alice. She put her hands on the table and leaned forward. Her angry gaze almost matched the girl in the photo's.

"It's not like you would have come if I'd told the truth. I had to say something you'd believe. David, you understand right?"

David opened his mouth to answer, but changed his mind when he saw the look on Alice's face. "That was not cool, man."

Grant frowned. "Aww, you're taking her side? What happened to you, man? You used to be cool."

David collapsed on the table and reached his hand out to Grant. "I can't help it. She's got me on a leash of love. Save me quick before I do something out of character!" David dramatically rolled on his back clutching his chest and slowly slid off the table, playing dead. A few moments of silence passed. Grant pantomimed removing a hat and bowed his head.

David suddenly stood up and said, "Actually, it sounds like a good lead. We should at least check it out."

Alice sighed. "Fine we'll go investigate. Did you get a possible location?"

"You bet I did," said Grant. "The guy's name is Percy Jackson. He goes to Goode High School in New York, New York. I say we go undercover as students and find out the truth about these masquerading marauders."

"What's high school?" asked Dawn, suddenly appearing next to Grant, who trips over his chair in surprise.

"Dawn! Were you spying on us the whole time?"asked Alice.

Dawn took a bite of the apple she held in her hand. "Only after I heard my name." She had long white hair that passed her shoulders. She always wore a white patchwork cloak with the hood down. She never went anywhere without it since it was given to her by her mother. Alice and Grant once took Dawn shopping, only to find that fashion transcends time. Dawn quickly picked out several outfits that somehow matched the white cloak. She was currently wearing outfit number 8.

"I'm glad you're here, actually," said Grant, picking himself off the floor. "That saves me having to explain the whole thing again. We're going back to high school and you're coming with us. It's time you seen what teenage life is really like in the 21st century. But, whatever you do, if you're at a party don't eat the brownies."

"I don't know what those are."

"I thought Matt was in charge of explaining desserts. Actually, come to think of it, that was a bad idea."

"Yeah, I was homeless for 13 years, remember?" said Matt from the doorway behind Grant.

Grant almost fell over again. "Geez, is everyone trying to give me a heart attack today?"

"If you're going to school I want no part in it."

"I don't mean to insinuate anything, but Dawn's going with us. I'm sure there will be a lot of guys hitting on her," said Grant slyly.

"They're going to hit me!?" exclaimed Dawn.

"No, Dawn, it's a figure of speech," explained Alice. "It just means that you may acquire gentleman suitors in your time at high school."

"Why do all of your figures of speech sound so awful?"

"Alright, I'll go," said Matt. "Someone's gotta look out for the time-traveler here. Nobody will hit you or hit on you while I'm around."

"It's settled then," said Grant. "Pack your bags tonight cause tomorrow we leave for Goode High School."

So, that was my first attempt at fanfiction. I hope you enjoyed it. The crossover characters are coming next chapter, I me know what you think. I'm always happy to hear some feedback.
