This takes place after BOTL, but before TLO, so Percy and Annabeth aren't a couple yet. Anyway, I got this idea from watching a bunch of movies with this theme. I know I keep saying that I want to finish my stories before making new ones, but I couldn't help myself!

Disclaimer: I don't own PJO!

Percy's POV

"What did you do to me?" Annabeth yelled as she shook my shoulders. Actually, it was more like me yelling at myself. It was really weird, like looking in the mirror every time I looked at her.

Okay, in order for this to at least sort of make sense, let's go back to last night. Annabeth and I were walking through the woods together after curfew. We had come back to camp for Labor Day weekend, which was kind of like the end of summer for us. We wanted to spend some time together before we had to worry about too much work at school. Well, we wanted Grover to come with us too, but he had left camp a few weeks ago when we went back to school, so it was just the two of us. That made it sort of awkward, but we were just friends.

Anyway, we were just talking about school when I heard the rustling of a bush and shushed Annabeth.

"Did you hear that?" I asked. Annabeth listened and her eyes widened as she nodded.

"Let's see what it is," I whispered and we followed the sound.

"Over there," Annabeth pointed and we tiptoed there.

"Huh," Annabeth muttered when we reached the spot. "I could've sworn-" she was cut off by a bright light that disappeared as soon as it appeared.

"What was-" I started but suddenly doubled over. I wasn't sure what was going on, it felt like I didn't have control over my own body. I finally was able to stand up and realized the same thing had happened to Annabeth.

"Are you okay?" I asked her. She stood and looked at me.

"Yeah, I guess, but what was that?"

I shrugged. "I'm not sure, but we should probably get back to our cabins before we get caught, or worse." She nodded and we headed back.

Annabeth's POV

I woke up when I heard someone closing the cabin door. I looked around the cabin to see all the beds already made. I must have overslept, which made sense considering how late I was up last night with Percy. I yawned and pulled the covers off of me. That's weird, I shaved my legs yesterday, how did they get so...hairy? Weird. I put my feet on the ground...no, not the ground, someone's clothes. Sloppy brothers. I walked over to the bathroom.

"Percy!" I said when I walked in. "What are you doing in my cabin?" He didn't respond. Then I realized something: his lips moved when and only when mine did. I lifted my right hand, then my left, watching Percy to the same.

"Stop that!" I said. Then I realized something else very important: my voice wasn't my voice. I felt my head, hoping to feel my curls, but no. Instead I felt straight hair. Short, straight hair. I looked down. My body wasn't mine. It was a guy's body. I screamed as I realized what had happened. I was in Percy's body.

Percy's POV

I woke up to the sound of a scream and jumped up out of bed. I went outside to see what was going on, half expecting the camp to be under attack or something.

"What's going on?" I asked a girl. I heard Annabeth's voice and I looked around, but there was no sign of her. Weird.

"I'm not sure," she said. "It came from the Poseidon cabin. I think it was Percy." She walked off, leaving me confused.

"Annabeth!" someone called and I recognized the voice as Selena. I looked around for Annabeth, if Selena was calling her, she must be nearby.

"Annabeth!" Selena said and approached me. "Hey, some thing's up with your boyfriend, I think you should go check it out."

"Annabeth has a boyfriend?" I asked, once again confused. "Since when?"

"Fine, alright I'll stop teasing you, but it's so obvious you like him." She ran off, leaving me even more confused. Then I realized something I hadn't realized before: my hair seemed longer than normal; I could feel it going past my shoulders. I picked up a strand and examined it.

"This isn't my hair," I said aloud, looking down at the curly blond strand of hair. "It's..." I felt my eyes widening as I put everything together. I screamed, well it wasn't really my scream, it was someone else's. Annabeth's scream.

Well, I hope you enjoyed it! :) What's going to happen now? :O What about when they have to go back to school? Review! Please and thank you! :D
