About ten years before the Cullens move to Forks they meet a different vampire. She has the gift of mirror but also the gift of being able to make herself and those around her more human. She's Jasper and Alice's mate and the three are beyond close. But she doesn't like humans that much. Or rather doesn't like humans getting close to her family. Let's see what happens when Bella meets and gets close to the them. In this I'm gonna have Bella eventually be the mate of Carlisle and Esme. This is gonna shake things up but it will turn out well I hope.
