All Heroes of Olympus characters belong to the one and only Rick Riordan. All Harry Potter characters belong to J.K Rowling. This is my first fanfic and I hope you enjoy it. Set after the war with Gaea (In this fanfic, Leo survives) and before Deathly Hollows.

Harry's POV

"Where are those bloody Americans?" Ron asked. I had to agree. Me, Ron, Hermione and the Weasley's were waiting for those American exchange students at the Weasley's house. We'd been waiting for half an hour an everyone was becoming impatient.

Suddenly there was a blinding flash and about 10 kids appeared out of nowhere. Most of them wore purple and orange T-shirts with faded letters.

"How are…"Mrs. Weasley began but was interrupted by a boy with elfish features.

"Hi, I'm Leo Valdez. I'd continue my introduction but I must ask, Where the Hades is the toilet?"

I was a bit confused but pointed towards the toilet. He ran and slammed the door. I almost swore I could see fire coming out of his hair though that would be ridiculous. Everyone winced as sounds of puking were heard from the toilet. At last, he came out, looking very refreshed.

"Next time, tell Iris to transport us using another method. That was an insane ride!" he gasped. He sat down heavily on the sofa and the Weasley's ushered the others to follow.

I quickly scanned the new group. There was a girl with Asian skin and brown choppy hair grasping the hand of a blond dude with electric blue eyes. Another girl with short punk-styled hair and had the same eyes as the boy. They were probably related. A sumo-built guy with close cropped black hair smiled shyly at a dark skinned girl with unusual golden eyes. Beside them, a girl with messy blonde hair and grey eyes had her arm around the shoulders of a black haired boy with sea green eyes. Actually, he looked a lot like me but minus the glasses and scar. A boy with black clothes sat a little apart from the others looking quite uncomfortable.

"I'm Mrs. Weasley These are my children, Ron, Ginny and-" Mrs. Weasley said.

" I'm Fred. He's George. We're twins.!" Fred yelled

I thought I heard the blonde girl whisper Stoll Twins though I wasn't sure. "This is Hermione and Harry"

I waited for them to ask questions or gasp in surprise. Instead, they shared a look that I didn't understand. The blond girl spoke up. Her voice was mature and serious.

"We'll introduce ourselves. I'm Annabeth Chase" She said.

"I'm Hazel Levesque and this is Frank" The dark skinned girl said, pointing towards the chubby guy.

"Hi, I'm Piper and this is Jason and Thalia. They're brother and sister." The choppy haired girl said. The blonde dude and punk girl waved.

"I'm Percy Jackson. This is Nico di Angelo." My lookalike said, nodding towards the emo boy. The boy grunted in greeting, not making eye contact.

"AND I-" Leo stood up. "-AM LEO VALDEZ. ALL DA LADIES LOVE LEO!"

Hermione giggled a bit. I noticed Ron glare at Leo. We sat awkwardly for a moment before shaking hands.

"So," Mrs. Weasley took out a piece of paper. "You're all going to Hogwarts."

"Wait, Hogwarts?" Thalia asked, smiling. We all nodded. The Americans broke out laughing their heads off. Leo doubled over and rolled on the floor.

"Hogwarts? Pig skin!" He yelled and laughed harder.

"You named your school after Pig Pimples?" Annabeth laughed, tears forming in her eyes.

"Boar zits!" Jason said. The laughter increased.

I could hear water somewhere in the pipes and thunder outside. I looked out of the window but the sky was clear and the Sun was shining brightly.

After everyone, almost everyone, calmed down, we continued. The boys shared and Ron's room upstairs and the girl shared a room with Ginny and Hermione. Ron was scheduled to sleep in my room.

"Are you guys from a wizard school in America?" Hermione asked.

"We're from…στρατόπεδο ετεροθαλείς." Annabeth said in some weird language. "Our first headmaster was Greek."

"It's true" Piper said. I found myself believing her.

"Got your wands?" I asked.

They pulled out theirs and i could see their eyes twinkle as if wands were the best weapons in the universe.

"Books?"

"Upstairs. In our bags by Magic!" Percy said and the others grinned.

"It's settled." Mrs. Weasley said. "All of you will be Sorted tomorrow."

"Time to eat" Ron said excitedly. "Let's go."

The guests nodded fast. They must have skipped dinner considering how late it was . I led them to the table and Mrs. Weasley placed a charm on the table. It grew twice its length and the chairs doubled.

Percy's POV

Chiron couldn't have chosen a better quest group. After the emergency call from a guy named Dumbledore who looked a thousand years old, we were set on a quest to save the Golden Trio. Actually, we were supposed to protect Harry, who looks a lot like me. The nerdy and more serious type of me.

So there I was, sitting awkwardly around a table that had expanded before my eyes. I doubted the Hephaestus Cabin could make a table like that. Not judging their abilities. Hecate had given us wands blessed with magic. All I could see was a scrawny piece of stick.

"So," Annabeth started. "How's this wizard school, Hogwarts?" I could see my friends struggling not to laugh.

"It's awesome!" One of the twins yelled.

"Especially with professor Dumbledore as the headmaster" The other one said.

"I like DADA"

"Nah, Care of Magical Creatures is the best!"

"Boys" Mrs. Weasley said sternly. They faltered and I grinned like an idiot. She was so like my Mum.

"Hogwarts is the best wizard school." Hermione bragged. "It has moving stairs and cool dorms. The foods are tasty and the subjects are very interesting."

"Boring" Ron corrected. Hermione glared.

Mrs. Weasley bought a platter of food and placed it on the table. Nothing was blue. I sighed but my stomach growled, eager to be fed. We dug into roasted potato, peas and chicken. Beside me, Leo nudged my arm. He held out a ball of fire in his hand. I nudged Annabeth who nudged Piper who nudged Jason who nudged Reyna who nudged Hazel who nudged Frank who tapped Nico lightly on the shoulder. We needed a diversion. Leo stood up and said in an obvious tone

"I need to go to the bathroom" He walked behind us and placed his hand in between our seats as fast as he could without being noticed. Thank gods he was small for his age. I quickly whispered Poseidon and threw in part of my chicken. The others did the same.

What happened next was my fault. I knew I shouldn't have asked but it just happened.

"Mrs. Weasley?" I asked. She turned. "In your opinion, are sea disasters worse than sky disasters or are sky disasters worse?"

I'm such a Seaweed brain. Jason and Thalia leaned forward eagerly and the others face palmed. Annabeth kicked my legs and I grunted.

"Well," Mrs. Weasley said. "If you fell from the sky, your death would be short and quick. Drowning though..." She shuddered. "I guess sea disasters are worse."

"Yes!" I said, a little too loudly. Everyone stared. "Me, Jason and Thalia made a bet. I went for sea. They went for sky." Big save.

Outside, thunder boomed and the winds howled. My first thought was Uh oh. My second was Gah!

Why? A lightning happened to zap a tree nearby the house and set it ablaze. Mrs. WeaSley cried out in horror and the Demigods and I ran out side. Should I say a plan forms in my mind when I'm in danger. I took a bucket from the front of the house and filled it with water from my hand. I threw the bucket and doused the tree with water. As the water flew in mid air, I made it spread like an umbrella around the tree.

"What happened?" Mrs. Weasley asked. "Wandless magic is very hard to do!"

I showed her the bucket and she sighed. The others walked back in but Annabeth stayed beside me. She judo flipped me and helped me up. I winced but smiled.

"Sea disasters are better!" I whispered in her ear.

"Yes, it causes a whole lot of disasters" She replied giving me a kiss.

Please review and share your ideas. I'd really appreciate it.
