It's so exciting when a book catches traction you didn't even expect (or completely did expect!), and so frustrating when a book never quite catches the traction you know it deserves. But either way it doesn't change the book, it doesn't change how much I love that book, or how thrilled I am to be publishing it.

There was a stage inside it and a crank on the outside that would rotate something, like a tiny tree carved of cork, onto the stage, and then the thousands of little mirrors would multiply that one tree so that the viewer would see an infinite forest instead.

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 loved reading historical novels when I was young, but I definitely don't think I wrote one. When I read my book through, when it was completely done and in printed galleys, I was surprised by how uninterested in the passage of time and history the book seemed to be. Even though you can feel it all there, that's just not what it's focused on.

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.

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 would be researching seventeenth-century garden design or I would be doing something with Pepys, but I just kept using all of it to write about Margaret Cavendish. It took me a long time to realize that I just wanted to write a book about her. Years.
