Hey guys! My tests just finished on Jan 31st so hopefully I'll be updating way more mow! Woot woot! :D I really hope you like this, the idea might be a bit overused and the characters might be OOC. It's set after TLO and before TLH, and in HBP (sixth book). Pairing are: Percabeth, Thalico, Heron, Hinny (basically mostly canon pairings). Others will be added when I think of them. Enjoy!

Disclaimer: I don't own PJO or HP. *sobs brokenheartedly* Why? WHY?

Percy's POV

It was a normal day at Camp Half-Blood, or as normal as it could get after the Titan War. All the campers were helping to repair the old cabins and build the new ones. My dad, Poseidon, had allowed some Cyclops to help us as well, along with Tyson. Even Clarisse and

I were getting along for once, getting along being not coming close to killing each other a million times a day. The Hunters were also here to help, and I wasn't sure what I felt about that: Hunters=Thalia=MAJOR Fights Between Her and Me, but I like her too. Not in that way though! Even Nico was here; those undead skeletons he summoned were a great help.

While we were taking a break, Chiron called Nico, Annabeth, Thalia and I to the big House. He said it was important. I hoped some other problem hadn't sprung up somewhere, but luck is never on my side.

"The gods have a quest for four demigods, and you have been chosen because, between us, you four are the strongest," Chiron said cheerfully. He then went on to explain about wizards and wands and spells, and he said that our mission was to go to some place called Hogwash or something like that and kill Voldy-something. He said we had permission to fly to London and get supplies (they were giving us wizard money too!); we had to leave the next day. I only really started paying attention when Nico spoke up.

"Hey, is this guy named Tom Marvolo Riddle? Coz my dad was complaining about him, said he was a right pain in the ass," Nico said with a hint of anger. This Tom guy must be really evil or crazy, perhaps both. "Yes, Nico, they are the same people," he said. "Your suitcases will be placed in your respective cabins. You all can take a backpack each, make sure you pack plenty of nectar, ambrosia and drachmas, and don't forget your weapons. You will leave in an hour from now. Lady Hecate has blessed you four with magic for the time being so you needn't worry about anything. Only the teachers will know about your true identities, which have to be kept secret."

"Oh," he said, "And keep these, they are to render any magic done on you ineffective." He pulled something out of his pocket and gave one to each of us. Annabeth's was a grey owl, Thalia's was an electric blue lightning bolt, Nico's was a pitch-black skull and mine was a blue-green wave. We kept them in our pockets, thanked Chiron and left. From what I had heard and understood, we had to fly all the way to England, go to some gods-forsaken school, kill some evil dude and come back alive, all without telling anyone anything real about ourselves.

Piece of cake. Not.

I went to my cabin and, sure enough, there was a sea green suitcase with a trident on it in a corner. I chuckled; obvious much, Chiron? I could pretty much guess what the other trunks looked like and not be wrong. I found my backpack and threw in a couple bags of ambrosia, a thermos of nectar, a pouch of drachmas, enough candy to last me a few months and this bag full of strangely shaped coins I found. I put on the watch that changed into a shield; Tyson had made a new one for me, which had all our adventures from my first quest right up till the Second Titan War. I have a sneaky feeling Grover was the one who helped in telling him about the other ones.

Finally, I changed into a sea green t-shirt, blue hoodie and jeans. I was done in twenty minutes.

When I went out, Annabeth, Nico and Thalia were coming out at the same time. Their suitcases looked exactly as I had guessed: Annabeth's was light grey with a dark grey owl, Thalia's was a startling blue with a white lightning bolt and Nico's was dark grey with a black skull. I guessed they had packed the same things as me, with different weapons. We went to the top of the hill, where Chiron was waiting for us with some letters in his hands.

"Your parents have been informed," he said, "and you have to give these letters to Albus Dumbledore, who is their headmaster. As exchange students, you are exempted from wearing robes. You can get wands, owls and other necessary items from Diagon Alley. Hagrid will show you around. Good Luck!" He smiled kindly and waves us off. I wish we got a break or something, but evil doesn't exactly go on a holiday.

Argus drove us to LaGuardia Airport, from where we caught a six-hour flight to London. I think Annabeth was the only one who relaxed even a bit during the entire flight. I was silently praying that the gods *cough* Zeus *cough* didn't strike me dead with lightning. I only relaxed once we were on solid ground. We collected our suitcases from the luggage belt, and at the exit, there was a giant man, whom I thought was Hagrid, holding a sign that said in big letters:

Pceyr Josckan, Abenenth Cahes, Talhai Garec nad Noic di Agelon

I finally made out that it said: Percy Jackson, Annabeth Chase, Thalia Grace and Nico di Angelo, but mostly because the man was calling our names out loud. The people next to him looked quite annoyed. I couldn't really blame them. The loud man reminded me a bit of Tyson: large and clumsy and welcoming and friendly. "Dumbledore's told me all 'bout yer," he said cheerfully. He lowered his voice. "Yer don' hafta worry, I won' tell anyone, I swear."

We got on the subway and got off at a random place; it looked like any old city. We went into a dingy place that looked like a pub. "This is the Leaky Cauldron," he said, "Yer'll stay here fer the nigh'. I got rooms fer all o' us. Righ' then, you lads go in one room an' the ladies can go in th' other one." We took our trunks, split up and went to our rooms, but not before I had kissed Annabeth goodnight. Out of the corner of my eye, I saw Nico awkwardly hug a blushing Thalia. Annabeth must've seen it too, because she raised an eyebrow at the same time as I did. We communicated silently: Quiz Nico/Thalia about this.

Once inside the room, I turned to Nico, who looked a little pink. "Well, someone's got a crush," I teased him and Nico glared at me half-heartedly and went inside the bathroom to change. I changed and waited for Nico to come out. He eventually did, and wasn't looking at me. "I've got only one question, Nico," I said, "how long?"

Nico sighed. He knew I'd got him "Ever since I saw her. Happy now?" He glared at me, and I knew he was telling the truth. He looked apprehensive, even fearful of my reaction. I smiled. "Good luck, mate. There's an outside chance she's not part of the Hunters now." He huffed and went to sleep. I was out cold the moment my head touched the pillow.

Annabeth's POV

I kissed Percy goodnight before going to my room. However, I hadn't missed Nico hugging Thalia; I just have to ask her later. When we reached our room, Thalia and I quickly undressed and got into bed. I crept up silently behind her and started tickling her. Have I mentioned that our dear old Pinecone Face was super ticklish?

"Annabeth… stop… please…" she begged me, red-faced and hoarse from laughing. "All right, but only if you tell me what that was back there," I said, pinning her hands behind her back. "You don't trust me, Annie?" she said, pouting. I narrowed my eyes. "No. Now tell me what that was all about. And don't call me Annie!"

"What is this 'that' you're talking of? I don't like Nico!" Thalia said, blushing. I looked at her suspiciously; I hadn't said anything about her liking Nico… My eyes widened and I almost squealed.

"Oh my gods Thalia! Why didn't you tell me?" I said, my eyes wide and a goofy grin on my face. Although I couldn't really blame her; Nico had grown up to be rather handsome, I guess. I did NOT just think that!

Thalia hung her head, she knew when she was beat. "I… I told Artemis that I didn't want to be a Hunter anymore. And I don't! I don't want to watch you guys growing to be old and dying while I'm sixteen forever!"

"But that's not all, is it?" I asked slyly. Thalia blushed deeply. "Quit teasing Annabeth! You know what I mean!" She protested.

"What do I mean?" I asked innocently. Thalia sighed. "I… I think I love him," she admitted to me. This time I really did squeal. Wait till I tell Percy! The look on his face will be priceless! But he might accidentally tell Nico because he's such a Seaweed Brain. The shock of the century will have to wait. But it's really visible that Nico is totally gaga over Thalia. I didn't even suspect Thalia! Well, maybe a little. I am a daughter of Athena.

But I'm totally drained now, and judging by the look on Thalia's face. She is too. I wonder if she has wet dreams… Mind out of the fucking gutter, Chase! I severely reprimanded myself and went to sleep while dreaming about Percy in a way that would make him blush. Really hard. I groaned in my sleep.

Seriously, what is wrong with me today? Are Aphrodite and Eros really so mad at me for telling them that makeup is stupid, and so is lust? Aargh!

Percy's POV

The next day we woke up around ten (we were tired!), had breakfast and headed to a place called Diagon Alley. The place was bustling with people wearing weird, flowing robes and some had pointy hats. They all talked in a British accent, but they looked afraid of something, as if someone was going to sneak up and kill them. I didn't pay much attention to them, though they looked at us weirdly.

We first went to this bookstore. Annabeth was having the time of their life, but she didn't buy anything extra except for this huge book on history and architecture. I had to suppress a laugh. Typical. We bought all our books and ran into three teens who looked about our age. One was a red-haired, freckled boy, one of them looked a bit like me, but , with glasses, skinnier and not tanned, the last one was a girl with bushy hair and a know-it-all attitude. I instantly knew that she and Annabeth would be best friends.

"Oh, hello Hagrid," she said pleasantly, then she noticed us. "Hi there. Are you new?" Nico rolled his eyes.

"No, we've been in Hogwarts for years, but we performed a memory altering spell on you so you wouldn't remember us," he said sarcastically. "Oh course we're new!" The girl looked miffed.

"Watch it Nicks!" Thalia elbowed him in the ribs. He winced and glared right back at her. "Sorry about that, he's really annoying," Thalia said nicely. "I'm Thalia Grace, by the way."

"I'm Annabeth Chase," Annabeth said smartly.

"Nico di Angelo," Nico said in a don't-care tone. Thalia glared at him.

"Percy Jackson," I smiled at the girl.

"Nice to meet you," she said, smiling back. "I'm Hermione Granger."

"Ron Weasley," the red-headed one said, nodding at us while looking warily at Nico.

"Harry Potter," the glasses boy said. He looked wary when he said this name. "Cool," we said. The three looked shocked. "Don't you know him?" The redhead asked curiously. I thought hard.

"Now that you mention it, I think Chi-I mean, our principal did mention a Harry Potter," I said, looking at the boy. His expression was unreadable. Annabeth looked surprised to see that I had actually been listening. "Well, glad to know they don't know about me in… wherever you come from?" he looked at us uncertainly.

"America," Annabeth supplied. "We're exchange students."

"Cool," Hermione said. "So, are you pure-blood, half-blood or muggle?"

We all looked at them uncertainly, then Annabeth said (again), "We're all half-bloods."

"Well, if yer guys are done talkin', we best get a move on," Hagrid interrupted gruffly. "See ya later, Harry, Ron, Hermione," he nodded to them and led us outside. We went to an owl emporium next.

There were all sorts of owls there, all of which suddenly became attentive and excited when we came in. I remembered that Athena's sacred animal was an owl. Of course they would be excited to see her favorite daughter. They used the owls to send messages, and we all needed one. Annabeth chose a beautiful-looking male snowy owl. Thalia chose an eagle. Nico chose a raven. That left me. I looked through the store, but I didn't find any owl I really liked, and because they didn't like me very much because I was the son of Poseidon, I decided to share Annabeth's owl. I paid half the money, of course.

The next stop was this wand place that Hagrid called Ollivander's. He said he had something important to do, but I got the impression that he didn't want to go in there. When I saw the shop, I knew why. The place was old, musty and creepy, and so was the old man who ran it.

"Ah, welcome, demigods," he smiled kindly at our shocked and wary expressions. "Do not worry, I am a child of Hecate," he explained and we relaxed instantly. "Dumbledore told me about you four. Apparently, your godly parents wanted to fashion these wands themselves. Quite understandable." He pulled out four boxes: one was sea-green with a blue trident on it, one was electric blue with a white lightning bolt on it, one was grey with a gark grey owl on it and the last was dark grey with a black skull on it. They were obvious, just like our suitcases.

"Percy Jackson," he said. I stepped forward. He took my wand out of its case. "Twelve and a half inches, blue coral and pegasi hair," he announced before keeping the wand in its case and handing it to me.

"Thalia Grace," Thalia stepped forward. "Twelve and a half inches, redwood and eagle feather," he said, giving Thalia her wand.

"Nico di Angelo: Twelve and a half inches, black poplar from the Underworld and"-he shuddered-"a shred of a dementor." He gave Nico his wand.

"Annabeth Chase: Twelve and a half inches, olive tree wood and owl feather," he said, handing over our wands. We thanked him, paid for our 'wands' and left as quickly as possible.

Hagrid was waiting outside for us. He took us back to the Leaky Cauldron, where we had lunch and went out to look around, with Hagrid of course. We passed a shop that had brooms in it and each of them had some sort of code written on the handle. Somebody said they were Quidditch brooms. I've gotta ask Annabeth about that, she probably knows. We also saw this candy shop and it being candy, we all went inside.

I was surprised at all the different and weird types of candy they had. There were Chocolate Frogs, Bertie Bott's every-flavored Beans, Licorice Wands, and tons of other stuff whose label I didn't bother to read. The lady at the counter was thrilled when I brought pretty much one of each. I don't know what type of candy it is, so I'm buying only one. i'm ready to bet five drachmas that it's better than mortal candy.

After the candy place, we just wandered aimlessly around until we reached this really creepy-looking place. There weren't very many people in it, and to me, the shops radiated pure evil. I tugged on Hagrid's sleeve. "What's that place, Hagrid?" I asked. Hagrid stopped fiddling with his umbrella and looked up in surprise. He cursed under his breath and quickly led us away. Not even Nico coud sneak away to check it out.

"That's Knockturn Alley," he growled as he led us away from there. "Best not ter go ter that area. Filled with dark wizards and Death Eaters." I snorted. I didn't think that Thanatos woud be very tasty, but a glare from Hagrid told me this was serious. "What are Death Eaters?" Nico asked. He was laughing, too. "They're the people who follow You-Know-Who." After that, he pretended to be deaf to anything we said and dragged us back to the Leaky Cauldron.

It was only then that I realized that You-Know-Who must be that Tom guy. Chiron had told me that everyone was really afraid of him, even of saying his name. But it's not like names have power in this world, I thought. Maybe it just holds fear. We lounged around for a bit and I IM'd my mom and told her everything. I even showed her my new wand. She seemed really happy for me, but also a little preoccupied.

'What's wrong, Mom?" I asked, worried.

"Oh, I just wish they didn't have to send you," she fretted. "The Titan War just got over and now you're going to stop another dangerous enemy?"

I smiled. "Mom, think of it as an honor. Only the four most powerful demigods were chosen. Being one of them obviously means something."

"It means that you'll attract more monsters, that's what." She did have a point. I ran my hands through my hair.

"Look, Mom, it's nothing to worry about. I'll be back before you know it," I said. She smiled sadly as it began to fade. "Be careful, Percy. Love ya."

"Love you, too, Mom," I called just as it disappeared. I sighed and lay down. The Achilles curse really was very tiring. I closed my eyes and went to sleep.

Tomorrow was going to be a long day.

So, what did you think? Good? Bad? Feel free to tell me anything you have in mind! I haven't read HP in a while, so correct me in your reviews if I get anything wrong. And really, I think I deserve some reviews for this cause I wrote this all in one sitting and it's over 3000 words. I'll give you virtual, delicious cookies!
