A/N Hello people! This is a rewrite of my other PJ/HP crossover. So, if you followed this before, welcome back! If you're just discovering this, welcome to the newer, better version of Harry Potter and the Son of the Sea God!

So I decided to do this because all of the Percy Jackson/Harry Potter fanfictions that I've read are just Percy Jackson and crew go to Hogwarts so I decided to do it the other way around. I hope you like this!

Harry P.O.V.

Harry groaned and sat up in his bed. He was in a hotel in Augusta, Maine. He had been told by Dumbledore's portrait to go to a place called Camp Half-Blood in Long Island, New York in the United States.

Of course Harry had asked why. Why in the world had they been asked to go to America? Voldemort had just been defeated all was well (mostly) aside from the occasional rogue Death Eater. Hogwarts' repairs were already nearly done, and Ron and Hermione had finally officially started dating.

But the deaths that had been sustained still pierced him at every step. George was only starting to become his usual, funny self, which was a relief because they all were worried that he would never be himself again since Fred's death.

Teddy Tonks was an adorable baby and was currently staying with his grandmother. He had shown no signs of lycanthropy whatsoever. So far, anyway.

After Harry questioned Dumbledore, he replied in his usual mysterious way. "It is not my place to tell." His portrait had said. "I assure you that you will find the answers when you get there." Harry had gone to Professor McGonagall for help, but she was just as mysterious.

"Dumbledore had his reasons, and if he told you to do it, I suggest that you do it, Potter. As a headmistress I have only just been informed myself—"

"Informed of what?" Harry had asked impatiently. "Never mind." She replied. "I cannot imagine why you need to go. So far, they have been able to take care of themselves. But you had better hurry. Whatever crisis is coming, they will need you."

Further questioning had gotten absolutely nothing. Finally Harry gave himself up for lost and asked Ron and Hermione for help.

After he told Ron and Hermione about it, they'd insisted that they would come with him to find it. He had protested at first, but eventually he gave in. He was grateful that they were coming with him. It was 6 months after the battle of Hogwarts, and Harry was hoping for some peace. Nope.

"Let's start packing the tent." Harry had said to Ron and Hermione. "Harry?" Hermione was looking at him, with an amused expression on her face. Harry turned around. "What?" he asked.

"You know we can just take a plane now, since an evil wizard isn't hunting you anymore?" Hermione smiled.

"Oh yeah." Harry said, embarrassed.

"What's a plane?" Ron asked.

"Harry?" Hermione's voice took him back to the present. "We should get going. "She checked her watch. "The plane leaves in an hour."

Ron grinned. "This is going to be fun." Ron really liked planes. Coming from an all wizard family, he didn't know anything about Muggle technology.

"Bit easier than apparating across the country." He'd said when they had boarded the plane to Maine from England.

As they sat in there plane seats, Harry thought about possible reasons that they had to go to this place in New York. Maybe there were some rogue wizards there? Or some magical creature that was terrorizing Muggles? It seemed like Hermione was thinking along those lines.

"Harry, why do you think that we need to go to this place?" she spoke quietly, as Ron snored away on the seat next to Harry. "I don't know." Harry admitted.

"Maybe some rogue wizards?"

"Maybe." Hermione said skeptically, and went into deep silence for the rest of the flight.

When they got off of the plane, they immediately went out into the open. "Thank goodness." Hermione said, breathing in fresh air. "I was getting claustrophobic in there."

"Do you think you should send Minerva to this Long Island place to let them know we're coming?" Ron asked.

"Sure." Harry agreed. Minerva was an owl Harry had bought, a couple of months after Hedwig had died. He had decided to bring her, just in case. He named her after his old teacher, Professor McGonagall, and the Roman goddess of Wisdom, because she was just as smart, if not more, than Hedwig. Harry wrote a letter and tied it to Minerva's leg.

"Be as friendly as you can, ok?" said Harry. "We come in peace." Minerva hooted, than took off into the night sky.

Percy P.O.V.

Percy woke to hear the breakfast horn shatter the morning silence. He yawned and stretched. He would have to get to the breakfast hall soon. He walked out of the Poseidon cabin, and met Annabeth on the way to the dining pavilion. "Sleep well?" Percy asked her. She shrugged. "Same as usual. Dreams." Percy nodded, and they were silent for the rest of the walk.

As soon as Percy walked out of the pavilion (which was delicious, by the way) a white owl landed right on his head.

"What the…" he shouted. "Grover!" Grover, his satyr friend, was staying at Camp Half-Blood for the week. He appeared almost instantly.

"What? What? Oh…" Grover said as he noticed that there was a bird on Percy's head. Grover made a soft hooting noise. The owl hooted back. They had a conversation like that for a few minutes, (at least Percy thought that it was a conversation) Grover looking more confused with each hoot. Finally, the owl flew away.

"What'd he say?" Percy asked.

"She said…um… she said that…" Grover stammered. "What?" Percy shouted impatiently. "She said that three… three wizards were coming!" he burst out.

"What? You mean like, story wizards?" Percy asked, confused.

"Or it could be some trick that the Stoll brothers are playing?" Grover asked hopefully.

"Maybe." Percy said, but there was a tingling in the back of his neck. This was the beginning of something, he thought. Percy was sure of it.

A/N Okay chapter one is in the books! For those of you who have read this before, you'll notice that I combined two chapters because they were both WAY short. Just so you know, I will leave a shout out at the bottom of each chapter to all of the people who reviewed on the previous chapter. So yeah, PLEASE PLEASE PLEASE REVIEW/FOLLOW/FAVORITE/ all three.
