The Twilight Twist

What would happen if Bella's mom had really been a Vampire and Charlie never knew his own now ex wife who ironically enough lives in Florida. Again long lost sister of Bella herself I love being the twin of someone else because then I'm not the oldest or the youngest. She was born normal, not meant to be. When our mom started dating Phil I was about 16 I hadn't seen my sister or my dad in a long time she couldn't take care of me and without telling my dad she sent me away to the Cullen's Orphanage place and I've grown up with the Cullen's we had just moved back to forks to the old house in the middle of the woods. My sister never remembered I even existed and our dad never told her.
