Forward: Seventeen years after BD (Part 1) things have most definitely have changed. Renesmee and Jacob never met and the Cullens fled Forks to save her from being killed by the pack.
Renesmee is now going to Acadia University in Wolfville, Canada (I'm not lying it actually exists) with two of her hybrid best friends. She's been fully mature for about ten years. The rest of the Cullens are living in Ontario (about a 14 hour drive {for a human who abides traffic laws}).
The rest you'll find out as the story progresses. Please enjoy!
