Margaret Cavendish was one of the people who came up in the course. That was when I started thinking about her as a character for a book, but my idea was for a totally different book. It had all these characters in it; Samuel Pepys was one of the main characters. He famously wrote these extensive diaries through the period that are really funny and sort of saucy, actually.

It's all just so fraught when you're writing and then going through the editorial process. It feels like this shape-shifting thing. When it's done, and you can't change a single word, it's a totally different thing. I was surprised by what that thing was.

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.

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 was sad to see some of them go. Like a magic lantern that would project images on walls and people would travel the countryside with these magic lanterns and tell stories. And there was this cabinet that you would walk up to and it had a little peephole and inside the whole thing was covered in thousands of little mirrors.

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 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.
