Hi guys. This is my first fan fiction, so bear with me. This story is set during Harry Potter's 6th Year, and right after the Titan War for Percy Jackson. I love reading crossovers, so I decided to write one myself!

Disclaimer: I don't own any characters from Harry Potter or J. K. Rowling.

Chapter 1: A Normal Day

Percy:

It started out just like any other day. I was extremely excited for the day. After the Titan War had ended, things had been pretty quiet around camp. Well, quiet for Camp Half Blood, anyways. New campers were arriving all the time, and they were all sons and daughters of minor and major gods and goddesses. Thanks to Annabeth, we now had a whole bunch of new cabins for all the new demigods to stay in. We still had archery, sword fighting classes, and the lava wall. The Stoll brothers pulled pranks on the other cabins, and it was no surprise to see Katie Gardner from the Demeter cabin telling Travis or Connor off for one of the pranks they had pulled.

Camp would always be home to me.

However, that wasn't the reason I was excited.

I was especially excited for the day because Annabeth and I had a special date planned. We were going out into New York City for dinner.

Now, I gotta say, I was excited, but I was also a little bit nervous. Hey, what can I say? I've been known to completely mess things up. A lot. But I told myself I would be fine, and not to worry. It was just Annabeth, for crying out loud. Little did I know that our date was about to go horribly wrong.

"Percy, are you ready?" Annabeth called into the Poseidon Cabin door.

"Yep, I'm coming!" I told her.

"Hurry up! We're going to be late!" Annabeth chided me.

"Okay, okay, I'm coming, sorry!" I said, rushing to the door. What I saw there made me stop in my tracks, speechless.

Annabeth was in a beautiful blue dress that showed off her slim build. She was wearing her Camp Half Blood necklace, like always. But was really made me stop and stare was her beautiful grey eyes that sparkled, her gorgeous princess curls, and the knowing smile that her lips curved into when she saw me at the door.

"Wow... You look... Wow." I said breathlessly.

Annabeth rolled her eyes at me. "Let's go Percy."

We walked through camp and past Peleus, the dragon who guarded the Golden Fleece. Neither of us said anything to the other, content to hold hands and enjoy each others company.

When we reached the bottom of the hill, Annabeth turned to me.

"So, how are we getting to New York?" She asked.

"Blackjack, of course!" I replied, smiling. She smiled back.

"Of course."

After dinner, which was amazing, might I add, Annabeth and I were walking down the street to an ice cream shop, hand in hand.

"So, did you like dinner?" I asked Annabeth for at least the fifth time.

Annabeth rolled her eyes at me. "Percy, I told you the last four times it was great. What make you think that I will say something different this time?"

"Sorry." I said. "I'm just a little nervous, and the ADHD doesn't help me at all."

"Percy," Annabeth sighed,"It's just me. We've known each other for four years now, and it's not like I've changed since we started dating. There's nothing to be nervous about."

"I know." I said, smiling at her. She smiled back and put her arms around my neck.

"Maybe this will help your nerves." Annabeth said mischievously, and leaned in and kissed me.

Now I have to admit, the kiss did help me a little. After I came out of the fog that Annabeth put me in, I was definitely less nervous.

That is, until I heard the growling.

Now, most normal people would hear the growl and think, 'Hey, we should probably leave before whatever that is attacks us.' I, on the other hand, wasn't allowed to leave, because I knew that whatever the monster was, it would probably attack me anyway.

"Did you hear that?" I asked Annabeth.

"Yes." Annabeth's bronze knife was already in her hand. I took the hint and uncapped Riptide, my bronze sword.

We both stared at the alleyway the growling was coming from.

"Probably a hellhound." Annabeth whispered to me. "Come on."

We inched towards the alleyway, moving towards the shadows. Looking down it, I couldn't see anything.

Suddenly, a large black shape sprang towards us with a snarl. I brought Riptide up in a shimmering arc, and Annabeth slashed with her knife, but what I took to be a large hellhound jumped over us and sprinted away down the street, squealing in terror.

Lowering my sword and turning to Annabeth, I could see my confusion mirrored in her eyes.

"Well, that was weird." I said.

"It was almost like it was running away from something..." Annabeth said slowly, almost to herself.

She glanced up at me, and then gasped.

"Percy..." She warned.

I spun towards the alleyway and my eyes widened.

A man dressed in all black, with a white mask on his face was pointing a wooden stick at us.

"Who are you? What do you want?" I said fiercely.

"How interesting. Two children with weapons are obviously not muggles. Yet you are obviously not wizards either. I think the Dark Lord will be very interested in you both. I suppose I should take you to him." The masked man replied.

"You're not going to take us anywhere." Annabeth said firmly.

"Oh, my dear, I believe you are sadly mistaken. Stupefy! Stupefy!" The man said, pointing at each of us in turn.

Everything went black.
