A/N: This is my first fan fiction, so I shall appreciate all comments. For all purposes, TLH never existed, but Leo will be here because I love him :D

Percy POV:

"Are you sure you have everything, Percy?" My mom turned to look at me in the backseat.

I swung my backpack over my shoulder, and climbed out of my moms' car next to Half-blood Hill, my favorite place in the world. "I'll be fine, mom," I replied. I was seventeen, and I've traveled across America multiple times without so much as a change of underwear. You could say I was a pretty resourceful guy.

"Don't back talk your mother Perseus Jackson, and come here and give me a kiss." Leaning through the car window, I awkwardly hugged my mom despite the lack of space for my lanky build. She ruffled my hair, then kissed my cheek even as I was protesting it. She drove off and I started climbing up the hill towards Peleus, the dragon wrapped around Thalia's tree.

~{O}~

I was walking towards Cabin Three when I heard a familiar voice, "Hey Dolphin Breath, should I warn your chica that she might have a little competition, cause I don't know about you, but I don't paint lips on my face!"

Oh crud! Mom's lipstick! I quickly wiped it off before turning to face one of the new campers I had met over winter break, Leo. I didn't know him that well, but we traded friendly banter, probably because we thought the same, at least comically speaking. I had no idea how he could figure out anything mechanical.

"Hey man! If you got any shorter I'd step on you! Speaking of my lovely girlfriend, have you seen Annabeth?" smiling down at him. His hands were always fiddling with something, today it was one of those McDonalds toys, he probably got it from Nico.

"She was walking into your cabin a few minutes ago, dude, but I haven't seen her since. But don't forget, tomorrow night it's you, me and Black Ops, okay?"

"How could I? I can kick some zombie butt, and yours! Remember when we got Nico to help us make a real life level-"

"- And he passed out for three days? It was so worth it. Gotta go, later man"

"See ya, lover boy!" I walked away with a wave over my shoulder and set off to my cabin with a new vigor, finally home.

As soon as I walked into the low stone bunker that was my cabin, Annabeth jumped up from where she had been sitting on my bed and threw her arms around me.

"Seaweed Brain! You were supposed to be here yesterday! Didn't you know how worried I-"

"Whoa, Annabeth, I'm fine, My mom's car broke down, and we had to wait for Paul to get back from his teachers retreat until we could use his." She was freaking out, turning me around and checking to make sure I had all my limbs.

"But you could have called-"

"-Your phone was off."

"Or emailed?"

"There's no internet here outside of the Hephaestus cabin."

"What about I.?"

"Ran out of drachmas at home," Pulling her down on to the edge of my bunk, I continued, "I've been out of contact for a lot longer than a few hours in the past; what's bugging you?"

"Wow, Seaweed Brain, that was almost perceptive of you," Annabeth replied with a laugh.

"And that was almost a compliment, but seriously, what happened?" Annabeth wasn't one to worry about me too much; we both knew we could handle anything short of a major monster like a Chimera easily. And now that I had the curse of Achilles, I was even harder to kill, "Annabeth, talk to me."

"It's Thalia," Annabeth blurted out, "She's gone missing."

"Wait, what?" How could the great Thalia Grace, the daughter of Zeus, leader of the Hunters, go missing? And how could Annabeth know, considering Thalia didn't live at camp?

"The hunters came yesterday, and Thalia went out late last night, saying that something was calling her. A huge thunderstorm passed through camp for a few minutes, and then Artemis came down and said that Thalia wasn't in this world anymore. I got this all from Hannah, you know the daughter of Hermes who joined two years ago?"

"Does Hannah matter right now, if Thalia is missing!" I almost wanted to say dead, because another world could mean Hades, but I knew that Thalia was the only link Annabeth had from when she was seven, before she came to camp.

"I never knew you cared about Thalia that much, Seaweed Brain. Actually, I thought you found her irritating."

"Yeah, well apparently, you like me pretty well despite how much I irritate you, but you never know..."

"Percy! Not the time!"

"I was kidding! But there's nothing we can do now, can we?" I said, trying to comfort her.

"No! We have to do something, right?"

"Like what, Wise Girl? We don't know where she went or how she got there. We don't even know if she's in this world! Besides, It'll be dark soon, and despite my invulnerability, I still remember how it felt to be shredded like a cut of meat my first summer. Let me tell you, not pleasant!"

"Fine, but we're going to look first thing tomorrow." I put my arm over her shoulder, and she leaned into me, nuzzling her golden hair into my cheek.

"Did you think I wouldn't look for her, even if you tried to stop me? You know me!"

"Fair enough," She replied, and we headed off to dinner in each others arms.

~{O}~

Later that night, I awoke suddenly to the sound of a voice calling my name. It sounded like... Thalia? It was a rhythmic chant of "Percy, Percy." I felt like there was a reason I shouldn't go, like deja vu, but I knew Annabeth would kill me if I didn't follow Thalia... I jumped out of bed and started walking, knowing that Riptide was in my pocket, and that was all I needed. The chant continued, adding more and more voices, but none that I recognized. Thalia's voice was louder than the others, and she sounded nervous. I started to run.

Before I even realized it, I was standing in front of a huge chasm that led into nothing. I suddenly noticed that Leo was beside me. We looked at each other, then leaped to what I suddenly realized was our deaths.

A/N: So, how did I do? I don't know if I like how I did the Percabeth fluff, so drop me a line and tell me how much it sucked? I'm up for criticism, but don't flame please, I like to have some self esteem. :D
