The Half Blood Exchange Program

Sophia Johnson is a sixteen year old daughter of Zeus who has practically lived her entire life at Camp Half Blood with Annabeth. Her best friends include Annabeth, Percy, Grover and Nico. One day, Chiron approaches the best friends and asks them to go on a different sort of quest. The five children will be sent to an unknown location in Scotland where they will be observed by a group of witches and wizards at a place called Hogwarts. The witches and wizards have no idea who these five children are, but it's their mission to find out.

A/N: This is post-Titan war and pre-Horcrux searching, so that all of the characters are the same age. This is simply for fun so no flamers, reviews appreciated! Many have people questioned, so Sophia will be two months younger than Percy, so that the prophecy still applies to him.

Chapter One

SPOV

We were all sitting in a car on this mysterious train, marveling at the beautiful scenery that passed by us. A kind older woman stopped by with a cart full of sweet treats. As Grover and Percy scanned the treats, I remembered yesterday as we received our quest.

Yesterday:

It was around 11 in the morning when I was summoned to the Big House to visit Chiron. I was practicing archery with some Demeter kids, Janice and Big Al. I was thanking the gods that I wasn't practicing with the Apollo cabin, despite the fact I am quite good at archery, there is no comparison to his kids. Let's be honest… it's in their blood.

I trudged up the stairs, brushing off some errant singes that the flaming arrows caused. Great. My orange CAMP HALF-BLOOD T-shirt was burnt all over the bottom. I would have to go buy some more shirts at the camp store.

As I entered the conference hall, my best friends were already there. Percy and Annabeth were seated next to each other, holding hands while Grover and Nico sat on the opposite side of the table. I sat at the bottom, directly across from the head of the table where Chiron sat in his human form. He sat forward, and cleared his throat. Instantly, my hands began to sweat. I was nervous. I made eye contact with Annabeth and I knew we had the same idea of what was going to happen: a quest.

"I was approached by a man I met many years ago and he helped me with a situation I had encountered. And now it is my turn to repay his debt. You see, my friend runs his own special school… A school of witch craft and wizardry." We gasped.

"You mean, the whole school is related to Hecate?" Annabeth questioned instantly, the gears rapidly turning in her head. Chiron shook his head.

"No, these children naturally have magic flowing through their veins. As I was saying, my friend, Professor Dumbledore, has requested I send some of my own campers to stay with him for the length of the school year, to not only educate his own students, but to give you some insight as well into their world. I have chosen you five because I feel you best represent our camp, seeing as we have a child from each of the Big Three, a satyr and a daughter of Athena, who played a major role in our war. Do you accept this quest?" He stared each of us down before we answered.

"I accept." Annabeth.

"Yeah, sure." Percy.

"I accept this quest." Me.

"Let's do it!" Grover.

A simple nod from Nico.

Chiron grinned at us. "Here's the fun part. These students have no idea what is going to happen. They will only be told your names and that you have only recently learned about their way of life. Dumbledore's plan is to figure out what students can figure out your secrets. You must hide your secrets, but also subtly drop hints as well. You leave at midnight tonight; Argus will drive you to the airport. It is about a 7 hour flight to Scotland, where you will take a train to the school and meet the staff who will introduce you to the entire school at dinner. Good luck, my demigods."

I walked out with my friends, stunned. Everyone began talking at once and my head felt like it was going to explode.

"Enough!" I shouted. They all turned to me, stunned. I took a deep breath. "You heard what Chiron said. We leave in a few hours. We need to pack." And with that, I headed towards Cabin One.

I was shaken from my memory as Annabeth screamed. I instantly pulled my bobby pin from my hair, feeling it transform into my hand into my sword. Yeah, my bobby pin is also my sword. It's awesome, just like Percy and his 'pen'.

She jumped up onto the couch we were sitting on and backed up as… wait. Was that a… chocolate frog? I scooted closer to it and saw it was moving, inching up the window before finally disappearing out the window. I touched the sword to my hair and it instantly retracted back into a pin.

We all looked at each other. What were we getting ourselves into?

The train didn't take very long and by the time we pulled up to the station, it was twilight. We shuffled off the train, lugging our suitcases behind us.

I was looking around, marveling, when I heard Grover release a scared bleat. I touched my pin, turning slowly. There was a man who was much larger than any average man but too small for a giant. He had a giant smile on his face. I lowered my hand, feeling more at ease than anticipated.

"'Ello! Welcome to Hogwarts School O' Witch craft and wizardry! Names Hagrid. Come on you lot. We are taking the carriages up to the school." Annabeth and I hurried to catch up with the half-giant while the boys hung back and talked.

Hagrid told us about anything and everything that had happened at Hogwarts over the past few years, including the story of The Boy Who Lived, Harry Potter. There was a dangerous, dark wizard who they called You-Know-Who. He murdered Harry's parents and then came for him, but his mother's love for him protected Harry, rebounding the curse.

I felt my jaw and stomach simultaneously drop as the castle came into view. Annabeth gasped and began speaking excitedly to Percy about Architecture, or something like that. I felt my palms sweat and grabbed Nico's arm for comfort. He scowled at me but didn't shrug me off. Nico and I had a complicated relationship. We were cousins, so our relationship was very much love hate, while Percy and I got along perfectly. I guess being a son of Hades dampens someone's social views.

The doors opened.
