Finding the form was really a very dynamic process. I went through a lot of shifting, trying to get it right. Because the writing took place over such a long time, it's hard for me to pinpoint when specific things happened, but basically the final version only materialized in the last two or so years. It was there, but it took me a while to see it and then to refine it after I'd seen it.

I was trying to focus on Margaret's trajectory as an artist, as a woman and an artist. Hopefully Cavendish experts won't be angry at me for anything I've left out. I feel like all the major movements of her life are there.

As a publisher what you are trying to build is a long life for a book, to help it find its readers in many different ways, whether or not it made this list or got that review, etc. I'm sure some of that thinking has been useful to me as a writer as well.

I sense people expect something to show for ten years. But I do feel like it is dense. Some of my own favorite books are slim, but there's a lot of weight and power in them.

The reason the middle section switches to third person is, well, this is middle age. This is the part in her life where she loses track of something that was driving her and has to figure out what's going to drive the next part of her mission, this mission to be an author. I had to push back away from her for a while before we could come up to that really lyrical close third in the final section.

But when I realized it was actually going to be this portrait of the artist, birth to death, I had to then discover who Margaret as a young woman would be. I had to find the different voices for her throughout her life. I had a lot of fun discovering that. I had a lot of fun writing the childhood sections. By imagining her childhood, I was able to come up with this voice that matures as she gets older.

I suppose also that watching marketing and publicity stuff play out from behind the scenes, making those plans and seeing each piece fall into place or not, each year, for each book, has made me a little more tranquil about the process for my own book than I might otherwise be.
