A/N: This is an AU story, I started writing it before HBP so it won't follow the book at all, I have my own ideas as to where it's going to go. Please read and review!

Disclaimer: No I don't own Harry Potter or anything but I wish I did…

My Greatest Mistake

Prologue:

I always wondered how it could have happened to me, I mean me! I was responsible, and at 17 I had so much going for me. I was Hogwarts head girl and the Gryffindor quidditch captain. My body had morphed from that of a child into a woman's. I had so much to look forward to, until I fell in love with my teacher. That's right I fell in love with the new Defense against the dark arts teacher, none other than Harry Potter, the boy who lived, my brother's best friend! The boy who caused me to put my sleeve in the butter dish when I was ten years old! Yes, the very same Harry Potter charmed me in my seventh year at Hogwarts.

I'll admit, our relationship wasn't completely legal, he was my teacher, but rules never stopped Harry before, or me for that matter. Our relationship was a secret, but as most secrets seem to be, ours was found out. There really was nothing we could do about it, we had planned to tell everyone about our relationship when I graduated, but something changed that. Something I like to blame Harry for, because without his sperm I would still be a carefree seventeen year old girl.

I suppose I should start from the beginning, my name might be helpful, I'm Ginerva Molly Weasly, now, Potter. My story begins, I suppose, in October, right around Halloween. For some reason Halloween always depresses me, I can't explain it, but sadness always lingers over me when the 31st of October comes around.

I was sitting in the heads common room being moody and sulking like all normal 17 year olds do at one time or another. All of my friends and the rest of the school were in the Great Hall eating their Halloween feast. So as I was sulking, Harry Potter, my childhood crush (and I'll admit I was still quite attracted to him) came into my common room, and at that moment, my world changed forever.

A/N: I know this is short, it's just the prologue, the other chapters are longer. Please read and review!
