I've decided that The Great Western will be my next book. I can't believe no one has fleshed her out into a full story. True the record is a little thin, and it is true several authors (Larry McMurtry and Cormac McCarthy) have appropriated the concept of her into other story lines. Some of it, no doubt, is because there are no known photos of her, but that plays right into my strengths, or, at least, to my advantage.
I have a hunch I can capture her visage, if not her complexities.
