This is my first PJO Fanfic please let me know what you think!

Prologue

Annabeth POV

It all started with a knock at my door. I had just gotten home from work when I heard it. I called out for them to wait but when I looked through the peephole there was no one there. I threw open the door and I almost tripped over the car seat that was placed in front of my door.

"What the Hades?" I mumbled to myself.

At my feet was a sleeping baby, with the baby there was a note with my name on it. I tried not to wake the baby up as I grabbed it.

Dear Annabeth,

You don't know me, it's probably best if we keep it that way. I never wanted a kid, I wouldn't know what too do when it came to raising the thing, but from what I have heard about you I know you will be a great mother. You do, however, know the babies father; we had a meaningless one night stand about nine months ago and this is what happened.

"Percy Jackson, Son of Poseidon," is how he introduced himself to me at that party that night. He told me that I looked an awful lot like his girlfriend, and after a few more drinks that's exactly who he thought I was. It was one night and the next morning I left before he woke up.

I met you once; you were buying baby clothes for your nephew. We were talking about baby names. You said that if you had a girl you would want to name her Dylan Blake Sophia. I didn't know who you were until Percy walked up out of nowhere and grabbed your bags.

So I would like for you to meet Dylan Blake Sophia Chase.

If you look at the Birth Certificate then you will find both yours and Percy's full names on there.

A few months before I gave birth, I legally changed my name to Annabeth Viola Chase. I know that now you'll try to find me, but you won't, that's no longer my name. I have attached the blood work that was done on Dylan, and on it you will find the weird anomalies that come along with being the child of a demigod. And if you just look at her eyes you will know that what I am saying is true. Dylan is Percy's daughter.

I can't raise a baby, I can barely take care of myself, but I know, I know that this baby will be safe with you, and that you will raise her to be a wonderful young lady. So please, I know you probably want to give her up, but please, don't put her through that, don't let her grow up thinking that there was no one who wanted her.

I hate for you to find out like this, but when I contacted Percy he said that he wanted nothing to do with us and that we had to stay away. But I just couldn't let Dylan grow up with out a father.

Sincerely,

No one of importance.

P.S. She really likes being bounced after being fed, and she gets really cranky if she'd up past nine. Oh, and she loves baths. She's six days old.

I just stand there staring at the note. I cannot believe that this is happening to me. What the Hades! How did this person even know where we lived?

I look down at Dylan when I hear a quiet yawn escape her mouth. She blinks up at me with eyes that haven't decided on their color yet. And she just stares at me, and as much as I just want to carry her to the nearest orphanage I know that I can't. Whoever left her here was right, she deserves to know that at least one person wanted her. I won't let her grow up the way that I did.

I swoop down and pick her up out of her car seat, pulling her close to my chest, and walk back inside.

"A.B." I hear Percy call, "who was it?"

I walk into the living room and find him lounging on the couch. When he sees me he smiles, but his smile falters when he sees what I'm holding.

"Percy, I would like to introduce you to your daughter, Dylan Blake Sophia Chase. And the funny thing is; she's not my kid. Here, read the letter." I toss him the letter and I just stare at him, bouncing Dylan, as he reads. When he's done he looks up at me.

"Is it true?" I ask him. "Is it true that when she asked for help you said that you wanted nothing to do with them?"

"What was I supposed to say?" He asks me. "I'm too young to be a dad! I'm nineteen! And you know what we're going to do? Plus, the kid probably isn't mine. First thing in the morning, we are going to the orphanage and we are going to give her up for adoption. Do you understand?" He asks me. "For all we know, this baby is the daughter of some woman that we've never met; who probably stalked us, and did drugs! You know that there is no way that I would ever cheat on you." I can't help but stare at this man, no this boy, in front of me, and wonder what happened to the man I loved.

"I understand, let's get some sleep okay? You go ahead; I'm just going to clean up the kitchen." I turn to walk away when I hear him call out to me.

"I love you Annabeth," he says.

"I love you too," I tell him, but this time I feel like I just don't mean it.

"Okay Dylan, it's just you and me. And you know what? You may not be mine, but you will be."

Percy POV

I wake up in the morning and I notice that Annabeth isn't in bed with me. I roll out of bed and check to see if she's in the bathroom. Nope.

"Annabeth? You here? Annabeth? Where are you?" I call as I wander through the house. Finally I give up and I walk back to our room. I don't know what it was but for some reason I just feel like I'm missing something.

Only later did I realize that it was my mind not wanting me to deal with the fact that her tooth brush was gone, her socks. Her clothes in general were all gone. My mind didn't want me to deal with the fact that half of our dishes along with her favorite mug, and her suitcase were gone.

I didn't notice any of these things until I found the letter that she wrote me taped to the mirror on my dresser.

My dearest Seaweed Brain,

Not that I can actually call you that anymore. You haven't been my Seaweed Brain for a long time. About nine months to be exact. We made a promise that everything would be alright as long as we're together. But you know what? We haven't been together, since the moment you went to that party.

The Seaweed Brain that I loved? He would not want to leave this baby to fend for herself in the system. Not after what his father did to him. As you probably already figured out, I'm leaving. I have known you since I was twelve, we've been dating for three years now, but you changed, and, even though I will always love my Seaweed Brain; you are not him. You are just a hollowed out replica of the man I loved, and I don't know where we went wrong.

You were the best thing that ever happened to me, and it kills me to do this, but I have to say goodbye. I love you, but that's why I'm leaving, like you said, you're not ready to be a dad. Hell, I'm not ready to be a mom, I am terrified. How am I going to tell Dylan that I'm not her real mother? How am I going to tell her that I left her father because he wasn't ready? And that because of that she will never have a father?

I don't know.

I do know however that despite all of your many faults, I will always love you. And I know that as long as you're alive I will never love another like I love you. But you need to move on and live your life. That's why I left in the first place. So do your self a favor and just forget about me. Because what we had? It's gone, somewhere along the way, we lost it. I hope that you really do become the world's best marine biologist. Because now you really do have a chance to follow your dreams, and you better make the very best of it Seaweed Brain.

Just remember, I love you Seaweed Brain.

Always and forever yours,

Your Wise Girl.

Oh my gods, oh my gods, oh my gods! She left! I can't believe she's gone, but I know I can't blame her. I was the one who pulled away. I changed and I didn't let her in. After a while, no matter what I did, I feel like she just forgot that I loved her. I stopped bringing her lunch at school, I stopped taking her out, I stopped making her coffee in the morning, hell I even stopped telling her that I loved her every chance that I got.

As I sit there crying; I tell myself that if I ever find her again, then I will be better. I can't believe that it took me losing her for me to realize that I had everything that I would ever need in my grasp and I let her and my daughter slip away. The fact that she was willing to raise a child that wasn't even hers in the first place, just hits me like a ton of bricks.

I grab my coat and my phone and I race towards the door. I'm already dialing the number when I'm flying down the stairs. "I will find her. I will find her," is all I chant in my head as I hear the phone ring; then all of a sudden "I will find her," changes into "I will find them."

"Hello?" I hear her voice.

"Thalia?" I ask her.

"Yes?"

"I need your help." I tell her as I run onto the New York sidewalk.

"I can't Percy, and you know why I can't." she tells me, but I can hear the pain in her voice.

"She's with you isn't she?" I ask her.

"I'm helping her start over, Percy, I'm sorry, but she doesn't want to be found, especially by you. You broke her heart yesterday Percy. And the kicker is? She didn't even find out that you cheated from you, she found out from a letter and a freaking baby! A baby that you didn't want. So, no, I am not going to help you. I'm sorry, but I'm just looking out for my little sister, and after what you did, I don't think that you should be around her right now. But just keep in mind; if she changes her mind, which for now, she's adamant that she won't, but if she does then she'll know where to find you." All I can do is stand there and try to stop crying.

"Thalia, please, I made a mistake! I want to fix this!"

"Percy you had nine months to fix this, but you didn't, you lied, to her face, about everything. Don't make this harder for her than it has to be Percy, just let it go, and act like this never happened."

"But Thalia! I love her! I can't lose her, she is my best friend!" I plead with her.

"Percy, I know that, and you know that, but does Annabeth know that? When, besides last night was the last time you told her that you loved her?" She asks me. As I think about her question I just feel like dying.

"I don't remember." I tell her, starting to cry all over again.

"Exactly, you want to know what she told me?" She asks.

"Nine months."

"Exactly! Nine months, Percy! How is she supposed to react after all of this?" Thalia's voice is softer now, and in the background I can hear a baby crying.

"That's her right?" I ask. "That's Dylan?"

"Yeah, yeah it is. And guess what Percy?"

"What?"

"She's beautiful, and she's amazing, and she's yours, but Annabeth is the one comforting your baby right now. I have to go." She tells me and I hear the line go dead.

As I stand there in the middle of the crowded sidewalk I promise myself that I will find them again, and I will make this up to them, and I will be the man that each one of them deserves and when I do, I will never, ever, let them go again. If it's the last thing I do, I will be with my Wise Girl again.

So that's the prologue, please R&R, and let me know if this idea is something that I should pursue. And the more reviews that I get the faster that I'll post. Thanks for reading!
