My sisters, we didn't like each other as kids. We were scared of each other, I think, but we've grown to love each other. It was fun to write about these sisters who were supposed to hate each other but really don't.
My son, Wolf, was born when I was past 40 and the author of a best-selling novel. That means he has grown up a middle-class child - one who sometimes asks me for stories of my childhood but knows nothing of what it means to grow up poor and afraid. I have worked to make sure of that.
