Dedication to the release of Taylor Swift's album RED :) What will happen when Edward finds Bella's songbook?

I knew that when my "better half" came to stay with Dad and I in Forks, everything would change. Being the shiny, new toy on the block was going to be awkward enough for my introvert twin. So it comes as a surprise to me that she gets us involved with the Cullen family. Not that I helped dissuade their interest much, after all I did break Edward's nose for making my sister cry.

Bella has moved on. She's engaged and is excited to have her wedding. She's engaged to Riley. What happens the Cullens reappear? Most importantly what happens when Edward comes back and wants Bella back? In this story Riley stays human.
