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.

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 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.

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 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.

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 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.
