Alright this just hit me. This is a challenge for anyone that wants it just P.M me if you do.
So Bella got pregnant with Nesse and almost died and was changed as a result but what if Bella was able to have Edward's baby because of her gift? Bella is still able to reproduce even as a vampire and all of her children are as well. Bella becomes the Eve of a new world that was created by the apocalypse that only the vamps and supernatural survive and thrive. The humans are struggling and are dying out. Well this sounded cool to me; and I haven't heard of the idea before. Oh and Bella can be paired with anyone and that should probably be encouraged.
