A/N: So just before I start, I'd like to say a few things. First of all, I have this week off, so I WILL be updating all of my other stories. Second of all, PLEASE review!

And third: Disclaimer: Unfortunately, I don't own any of the characters of EITHER Percy Jackson or Harry Potter.

Hermione POV

It was the day before the end-of-term feast, and everyone was jubilant over the end of exams. The mood was lighthearted, and no one seemed to care that a war was impeding between Voldemort and the rest of Wizarding society. At supper that night, when the plates had cleared themselves of food, Dumbledore stood up and motioned for everyone to stay seated.

"As you no doubt already know, Lord Voldemort" – this produced a gasp from many students, "is alive and at large. Now, the Ministry has confirmed this, however they would see us training to fight him as an uprising. So we can expect little help from them. However, an old acquaintance of mine, who is in America, has informed me that he will be more than happy to help us."

"Wait a minute," Ernie said. "Why are you telling us this? Are we going to be going to America?" "Precisely what I was going to say, Mr. Macmillan. However, only fifth-year students and older may come," Dumbledore added. "You will arrive there by Portkey. Of course, I will be going with you, as will Professor McGonagall.

If you wish to come, sign your name on this parchment before leaving the Great Hall. We will leave tomorrow morning after breakfast." The Great Hall instantly erupted into a hubbub of noise as the younger students left the hall and the older ones debated whether or not to go.

Harry, Ron, and I remained seated at the table. "I dunno," Ron said. "I mean, I think it would be a good experience. But how do we know this isn't a trap from You-Know-Who?" I elbowed him in the ribs. "Honestly Ronald, Professor Dumbledore would obviously have made sure it was safe before allowing students to go. I think it would be very interesting. I mean, we'll get to see how American wizards live and all. What about you, Harry?" Harry nodded. "Yeah, I think I'll go," he said. "I mean, the more allies we can get, the better, right?"

Ron and I agreed, so we walked up to the table and signed their names on the parchment. I had been expecting to see a full parchment, so it was surprising to see only about five other names. Ron, who had scratched his name onto the parchment, put down the quill and turned around before saying, "Uh-oh. I smell trouble." Malfoy and Pansy Parkinson had come up the steps to the table. Harry and I stepped away from the table just as the Slytherins reached it.

Harry stepped forward and said, "What do you want, Malfoy?" Malfoy sneered. "I thought I'd come along to America. It's a good excuse to get away from this place." He looked disparagingly at the walls of the castle I had learned to call home. He leaned forward and wrote his name on the parchment, then handed the quill to Pansy. I could tell that Ron was getting upset, so I started pulling him out of the Great Hall. "The slimy git," Ron fumed. "He's only coming along to spy on us for You-Know-Who."

Harry nodded. "Yeah. There's no way he's coming along to help us." I tried to change the subject – I hated talking about Malfoy and how horrible he was. "I'm really excited, though. I mean, we'll get to see Wizarding from a whole new perspective!" We had reached the portrait hole, and the Fat Lady looked sternly at us. "Well, come on, what's the password? I haven't got all night." Harry and Ron looked at me expectantly.

Of course they had forgotten the password. Just like them. "Polyphemus," I said. Next to me, Harry was explaining something to Ron – something about a Muggle card game Dudley was into. I left the two of them to their discussions and went up to my dorm to pack up.

Percy POV

I woke up, as usual when I was at camp, pretty early in the morning – around six thirty. I walked outside, and right into Annabeth, who was walking the other way and looking intently at a clipboard. "Hey!" she yelled. "Watch where you're… oh. Hi, Percy. Sorry. I'm just trying to put the finishing touches on the Hades cabin." I said, "Hi," in return. It got a little awkward between us, so she said, "Do you, um, want to go for a walk?"

I nodded and walked towards the beach. I sat down on the warm sand and patted the sand next to me. Annabeth sat next to me and slipped her hand into mine. "It feels too quiet without having to save the world," she said. I nodded. It was kind of boring, not having to go out on a quest every other month.

But it was a good kind of boring, not a bad kind.

Before I'd left to go to camp last week, Paul had told me that there was some strange weather and events going on over in England. I told Annabeth this, and she looked interested. "I know that Zeus and Poseidon are actually on pretty good terms right now, so they can't be causing it," she said. I agreed.

I didn't think that Zeus and Poseidon would have gotten so upset at each other so soon after the war. Annabeth was looking out at the horizon, but she turned to look at me. I leaned in towards her, and our noses bumped. "Oops," I said. Annabeth giggled. I held her shoulders and leaned in again. The kiss was a short one, but it sent an electric shock through me, just like that one time Thalia had gotten mad and shocked me by accident.

The conch horn sounded, and Annabeth pulled away. She smiled at me, tucking a strand of hair behind one ear. "What was that, Seaweed Brain?" she asked, and then smiled to let me know she was kidding. "Come on." We walked hand in hand to the dining pavilion, ignoring Connor and Travis's hoots and shouts of "Awww!"

Once we got there, Chiron stomped a hoof on the marble. "Campers!" he shouted. "May I have your attention! We will be having visitors this summer. They are from England, and they are what you would call wizards." One table over, Dan and the other Demeter campers started muttering in disbelief. "No way," he said. "There's no such thing as wizards."

Chiron stomped a hoof again. "Well, these people are wizards, and they do possess magical abilities. They need our help in defeating an adversary of theirs, a certain Lord Voldemort. We can expect them to arrive this morning, and they will be split up and stay in various cabins."

Grover had come to eat breakfast with me. He looked depressed. "What's wrong, buddy?" I asked him. He sighed into his coffee. "Juniper isn't talking to me. I think she might be seeing someone else." I leaned forward. "Come on, Grover. You're my best friend. I'm sure she's okay." He looked up at me. "Really?" he asked me. I nodded again. I was sure that Juniper wasn't cheating on Grover. We finished up and walked over to the climbing wall. Grover, as usual, got to the top in five minutes. Me? Well, it was painful, but I made it.

I had just gotten back to the bottom when Annabeth came running up. "They're here!" she said. I followed her to the river and saw about fifteen people all standing around and staring at their surroundings. "How did they get here?" I asked her. She said, "I guess they can appear from one place to another."

Nico came up behind us. "Like me," he said. I spun around – he still scared me by his ability to shadow travel. "Yeah," Annabeth said, grabbing Nico and pulling him into a hug. "I haven't seen you in a while," she said. "Where have you been?" Nico shrugged. "I was with my dad. I wanted to get to know him a little more." I was glad to see him, even though it had only been a month since I last saw him.

I followed the stream of campers walking towards the newcomers. From behind me, Chiron galloped up. He greeted a man with a wispy white beard, shaking his hand and saying something I couldn't hear.

The students all looked around my age, but one caught my eye. He had jet-black hair and a large, lightning-bolt shaped scar on his forehead. He looked around my age, maybe a little younger. As with the other students, he looked surprised that Chiron was a centaur. Were they expecting someone who looked like that old man Chiron was talking to?

Chiron had turned to us. "Campers!" he said. "These are the students from Hogwarts School of Witchcraft and Wizardry." Annabeth leaned in and whispered, "That doesn't sound so good." I agreed. I mean, witchcraft? Didn't they kill people for that in colonial times? Chiron continued, "Now, the Gryffindors will stay in Cabin Three. Percy, would you show them where it is?"

A group of students all wearing red ties stepped forward. I said, "Follow me," and walked over to the cabins. We walked past Clarisse and one of her siblings sword fighting on the grass, and a boy with red hair said, "Bloody hell! Don't you get hurt?" I looked at him. "Yeah, sure, but we have to train. I'm Percy Jackson, by the way." The boy said, "I'm Ron Weasley."

Hermione POV

The boy named Percy led us to a group of building shaped in a "U", and we followed him into a low hut on the left. What surprised me was that all the buildings were different. One cabin, off to the right a little, was barely completed. So the campers must be sorted into different cabins, just like at Hogwarts.

Inside, a fountain gurgled gently. There were gold coins in the bottom of the fountain, and when I looked up, I saw bronze statues of what looked like a cross between a horse and a fish. Percy sat down on the only bunk that had a bag on it and said, "You guys can have any of the other bunks. It's just me here." I wondered why he would be the only one in the cabin. Wouldn't it have been split evenly, like at Hogwarts?

Ron jumped on an upper bunk, and Harry took the lower one. Ginny motioned for me to pick any of the remaining three beds. I shrugged and said, "My name's Hermione Granger, by the way. It's nice to meet you." Percy nodded. "Same here," said Harry. "I'm Harry Potter, but you probably could tell that by my scar." Percy looked puzzled. "Sorry, no. I'm not a wizard, if that's what you think." I was surprised that Dumbledore expected help from non-magic people. "I'm sorry," Ginny said, "but if you aren't wizards… you clearly aren't Muggles – non-magic people."

Percy nodded. "You're right," he said. "I'm a half-blood. Well, technically the term is a demigod." I gasped. I had read myths about the Greek gods and goddesses over the previous summer, but I had never expected them to be true. "What does that mean?" Ron asked. That's when I decided I had better explain it to him before he got too confused.

"Well, Ronald, have you ever heard of the Greek gods and goddesses?" He nodded so I continued. "Well, in the myths they had children with mortals. So their children were known as demigods. But that's just in the myths."

Thunder boomed overhead. "You're right, Hermione," Percy said, "Except for one thing. They aren't myths. I'm a demigod too." "Wow!" said Harry. "So you're like half god and half human?" Percy nodded. "Who's your dad?" Ron asked. Percy stood up a little straighter. "I'm a son of Poseidon, god of the sea." Wow. He was a son of one of the three main gods. That was amazing.

Before I could say anything, though, a boy with dark skin, black hair, and what looked like a skull ring walked through the door. He reminded me of the gothic kids I would see when I was at home during the summer. What surprised me, though, was that he looked only about twelve.

"Hey, Nico," Percy said. "Guys, this is my cousin, Nico. He's a son of Hades." Nico waved. "Hey," he said, before turning to Percy. "Percy, Clarisse is outside and she wants me to remind you that she challenged you yesterday and that if you don't fight she's going to…" Percy cut him off. "All right, thanks, Nico," he said, and started to head for the door. "Come on, guys," he said. "Don't you want to see how we fight?"

So, how was it? I know it's an unoriginal plot line - actually, I'd like to thank AnnabethChase5450 for the idea. She's got a great story too, I would check it out if I were you!
