The Girl in the Legend. ~a twilight fanfic~

We all know the story of Bella and Edward, and we know about the Cullens, the pack on the reservation, and the Volturi. But the details after Renesmee's birth are vague and all over the place, that's because the stories needed to leave out a few very important details. If we had known the details sooner maybe somethings would have changed, maybe more secrets that where held by the volturi would be revealed.
What if Bella and Edward had two children instead of one, twins, two girls. Both astute and beatiful, but both had their differences. Atremis Marie Cullen born only a few moments after her twin sister, grew a bit stronger with her powers daily. She loved her family and her family loved her, but when the volturi came there was no memory of her but everyone that came to help remembered her.
This is the story of The Girl in the Legend, but what really happened to make her a memory in a legend.
