There are lines of geomagnetic force running through the Earth's crust, and most of the time, these run in opposing directions - forward and backward. In some places, they deviate and will cross each other, and when that happens, you kind of get a geomagnetic mess going in all different directions. I call these vertices.
All of my books have an internal geometric shape, and once I've seen the shape, then the writing gets much faster and easier because I now do know where we're going, and I know what's motivating these people, why they were here, and therefore, I have some good idea how they got there, and so I can fill in the missing chunks somewhat more easily.
I have no objection to well-written romance, but I'd read enough of it to know that that's not what I had written. I also knew that if it was sold as romance I'd never be reviewed by the 'New York Times' or any other literarily respectable newspaper - which is basically true, although the 'Washington Post' did get round to me eventually.
Whenever you're dealing with something that's difficult to describe, that you can't get across to someone in a sound bite, it sounds like the normal default is to pick what's easiest, and in the case of fiction written by women, fiction involving women, fiction involving any sort of relationship, the word that comes to mind is 'romance.'
Cultural concepts are one of the most fascinating things about historical fiction. There's always a temptation, I think, among some historical writers to shade things toward the modern point of view. You know, they won't show someone doing something that would have been perfectly normal for the time but that is considered reprehensible today.
I have never seen a script that hasn't gone through at least eight different iterations before they even begin filming, and frequently what is filmed is not what's in the script, because things change on the ground. An actor can't say a particular line. An actor will have a brainstorm and ad lib something utterly brilliant.
