It's interesting, editing can be so immersive for me that I've noticed that the authors I edit have a pretty profound effect on how I hear language for a while.

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.

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.

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.

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.

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.

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.
