Prologue:

The Big Three were never supposed to have any more children. And as far as I could tell, those three gods were (mostly) good at following this rule. And that is saying something because the gods were never good at following ANY rules. The only exception that I could find was Thalia Grace. And everyone could see how the daughter of Zeus ended up-at least anyone that was under her constant protection at Camp Half Blood.
Camp Half Blood. To anyone else, it's just a place. To some, just pointless words on paper. But it's the only home that I have ever known. The only home that was ever worth mentioning. The only home that ever really meant something to me. Scratch that- Camp Half Blood was more then just a home. When I came here, just ten years old, it was the only place I ever felt at really accepted at. It was the only place that I ever felt truly at peace. For the first time in my life there wasn't a father looking at me like I messed up his entire life. There was no step-mother who glared at me like I was going to kill everyone in the house, including her two darling little boys. Her kids became my father's children- in ways that I never could.
Thinking back, I really couldn't blame my step-mother for hating me. I was really young but I could still see the shadows in the windows, the creatures. I also could tell I wasn't a stupid child, so there was something off in the way that I couldn't read proper English without the words seeming to float off the page. Yes, I was young. But I was never blind. I was never care-free in the way that most young children are. I realized that there was something different about me. And those looks from my step mother confirmed it- I needed to leave. Now. Before I hurt someone- even someone in this family that cared so little for me. I guess that's why I made the decision to run way.
I would have died without Thalia and Luke. Thalia DID die. I used to think that it was my fault, and in a way, I believe that I still do. But as I grew older, I began to realize what being a half-blood meant. It meant that you usually die. It means that you leave your family behind. It means training and studying every day for years in the hope that you might live a few years longer (and hopefully make a difference while you do it). I wish every single day that Thalia had made it to camp with Grover and Luke. I wish it so much. But she did die, and I can't bring her back (because in a way, she was never truly gone). But I can't let her memory go in vain. I have to go an a quest. I have to study and train. For her sake. For her memory. For what she did to protect us.
No, the Big Three were never supposed to have children. They were never supposed to break their single rule. But thankfully, for me and for everyone, one did. And the child's name was Percy Jackson.

authors note/ Hi! This is my first fanfic. I know this first chapter seemed all over the place but I just wanted to summarize what we know about Annabeth's life before Percy came along. The first few chapters of The Lightning Thief won't be included (because they arn't from Annabeth's POV, duh. Anyway thanks for reading!
*I do not own any Percy Jackson characters*
