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.

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.

I can be a fairly hands-on editor, and when I'm editing someone I feel intensely invested in that writer and her work. I love helping to shape a book, and I feel very privileged to get to do that with writers I'm excited about. I think doing that work for the past six years has changed me, and it better prepared me for the questions and suggestions.

I'm not entirely sure what a historical novel absolutely has to be, but you don't want a reader who loves a very traditional historical novel to go in with the expectation that this is going to deliver the same kind of reading experience. I think what's contemporary about my book has something to do with how condensed things are.

I'm not sure running the press has changed how I write (though perhaps it has in ways I can't see), but it has certainly changed my relationship to how books get made.

Back then, when I had that original idea to write about the seventeenth century, the whole thing was set in 1666. I was thinking of Margaret near the end of her life, and that was the voice I heard for her.

So it was this multi-perspective, multi-character book, and it went through all of these different manifestations. I'm not sure there was a single moment where I thought to myself, Oh, I need to write about Margaret Cavendish. She just kept taking over the book I thought I was writing.
