Well, I've been reading a lot of FanFictions similar to this - Harry Potter meets Percy Jackson - but the thing that always annoyed me was the time difference. Harry is NOT the same age as Percy! He is 13 years older! So, for all of you out there that agree with me, I made this story. Hope you like!

Disclaimer: I swear, by the River Styx, that I do not own Percy Jackson, or Harry Potter. I wish I did. My life would be so much easier if I did. :'(

Harry Potter and the Lost Demigod

Chapter 1: I'm Sent Back in Time

Percy

I raised the knife to strike. Then I looked at Annabeth, at Grover cradling her in his arms, trying to shield her. And I finally understood what she'd been trying to tell me.

You are not the hero, Rachel had said. It will affect what you do.

"Please," Luke groaned. "No time."

If Kronos evolved to his true form, there would be no stopping him. He would make Typhon look like a playground bully.

The line from the Great Prophecy echoed in my head: A hero's soul the cursed blade shall reap. My whole world tipped upside down, and I handed the knife to Luke.

Grover yelped. "Percy? Are you…um…"

Crazy. Insane. Off my rocker. Probably.

But I watched as Luke grasped the hilt. I stood before him – defenceless.

He unlatched the side straps of his armour, exposing a small bit of his skin just under his left arm, a place that would be very hard to hit. With difficulty, he stabbed himself.

It wasn't a deep cut, but Luke howled. His eyes glowed like lava. The throne room shook, throwing me off my feet. An aura of energy surrounded Luke, growing brighter and brighter. I shut my eyes and felt a force like a nuclear explosion blister my skin and crack my lips.

Then everything went black.

When I came to, I estimated that about an hour had gone past. You see, I've become quite an expert at these things, because of the numerous times that I've been knocked out. Your body just suddenly starts telling you how long you were out cold.

I painfully raised myself up on my hands, until I was more or less in a sitting position. I groaned – my body felt like it had been picked up, battered around and dropped from a great height. Ironically, that was pretty close to what had happened.

After my head stopped spinning, and the pain subsided, I started to take an interest in my surroundings. I had assumed that I'd just been knocked out by the energy Kronos/Luke released when he stabbed himself, but as I looked around, I saw that I was no longer on Olympus.

I was on a path, by the side of a road. On each side of the road were two neat story houses, each with some lawn out the front. The one I was closest to was number 4, and I swear if the lawn had been anymore perfect, it would have had a sign next to it, saying, 'KEEP OFF THE LAWN,' in bright red letters. I wondered who would keep their grass neat to that degree. There certainly wasn't a demigod living in this house – a monster would have torn up the lawn in seconds.

As I sat, contemplating that thought, the door opened and a boy stepped out. I blinked. The boy could almost have been my double, except for the scar peeping out of his hair, his large round glasses and the general skinniness of him. He had black hair, and vivid green eyes – not sea green like mine, but more like….traffic lights!

I know, you're thinking, traffic lights? Whose eyes would resemble that? But this boy's did. His eyes had a glow to them as he looked at me – not Kronos gold eyes glow, but just a glow. However, I could see that he was suspicious, or afraid.

"Who are you?" the boy's voice interrupted my thoughts about his eyes. Blame the ADHD for my train of thought!

I shifted, attempting to stand, but failing miserably. "I'm Percy Jackson." I smiled at him, hoping to show that I meant him no harm. Unless he was a monster, but I doubted that. "And you are….?"

The boy's eyes widened. "Y-You mean… You don't know who I am?" he asked incredulously.

I frowned, scanning him should I know him? He looked about my age, but I didn't remember him from Camp Half-Blood. "Nope, sorry. Am I meant to?"

"Err….no! No, no, of course not. I'm Harry Potter." he looked at me again, maybe trying to see if I recognised his name.

I thought. Did I know a Harry Potter? Was he famous or something? Coming up with zip results in my brain, I grinned at him. "Well, hello Harry! Um… Do you think you could help me up?"

Harry stepped forward and grabbed my hands, pulling me to my feet. I swayed slightly, feeling a little light-headed. I needed sleep – the Curse of Achilles gave me invincibility, but made me much more tired, especially after a battle like the one I'd just fought. "Hey, Harry? Could you direct me to the Empire State Building? I have friends that I'm meeting there."

Harry looked at me strangely. "The Empire State Building? But that's in America!"

I stared at him. "But…you're saying…"

Harry looked sympathetic. "Percy, you're in England."

No. I couldn't be. I was in America. In Manhattan.

"You must be mistaken. I was in New York, America. Th-This can't be England!" I was starting to panic. What if it wasn't a joke, or a dream? What if I was in England?

Harry shook his head. "You're definitely in England. This is Number 4, Privet Drive, London. I live here."

My legs gave way. I needed rest so bad, and this news was too much. "Has the freak storm in America stopped?" I had to know if Typhon was gone.

"Are you sure you're alright? Because there is no storm in America."

I was puzzled. Surely Typhon would have been on the news. "Yes, I'm fine, just tired. Can you get me a newspaper?" Harry nodded at the strange request and ran inside to grab a newspaper. Two minutes later, he was handing it to me.

I flicked through it, but saw nothing about Typhon, or anything in America. I was about to hand it back to Harry when I saw the date.

I felt sick. "What's the year?" I asked shakily, begging every single god I knew that date on the newspaper was a typo.

"1996. Why? Hey, Percy! Are you alright? What's wrong?!" Harry's voice faded away as I lay back on the path. 1996. England. The words kept spinning around my head. Just before I lost consciousness again, I realised the truth.

I was in 1996, London. Thirteen years in the past, on a different continent, with no way of getting back.

Just to clarify, Percy is slightly distracted by Harry's eyes, but that is because apparently they glow like traffic lights. This is not a slash HarryxPercy story. Blame his ADHD for any wierd thoughts that may pop up.

Percy: Hey! I can't help it!

Me: I never said you could. I'm on your side!

Percy: Oh... um... I might just leave now.

Me: Well, I hope you liked this first chapter. Reviews? As many writers point out, reviews = more chapters!
