AU where Isabella is Kathryn's daughter and the identical twin sister of Kristin Kringle.

A/N: I just want to be clear, I do NOT ship Edward x Isabella. I am Nygmobblepot ALL THE WAY but I thought it might be interesting to give Isabella a little more backstory and explanation and perhaps (?) a bit more of a sympathetic side (maybe? IDK honestly I just wanted to write this LOL)
