"Why did you write My Sister Rosalie?"

Bella, and Rosalie, are trying the best they can to be true to themselves, even though, obviously in Rosalie's case, she has no idea she's being true to what's hurting her and Bella. And also Bella has no idea she is better than she thinks she is. But that's the beauty of this story.

This is a story about hope, even when you don't see it anymore. 

So.

I ... my daughter died. Rose Marie. And it hit the family so hard, even today, more than ten years later. Little Isabel said: "I miss Rose Marie." That hurt. A lot. And I wonder. Can she hope now? Who would she have been as a person? I wonder that. Would she have been happy, or sad, or selfish, or generous? I wonder if she's happy now, and I don't know that, and I'll never know that.

And so I wrote MSR. I don't know about Rose Marie, but maybe Rosalie can find hope, and maybe she can be happy, and maybe that can help, her, a little.
