I had all these sparkles I'd collected and wanted to work in, but when I originally started writing it and it was originally this novel about all these people set in 1666, what I was so interested in was the New Science.

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 obsessed with the scientific instruments people were building and all the weird experiments they were doing. I did actually wind up working in some of that, but there were whole sections I'd written about these instruments that ultimately had to be abandoned when I realized that the book really was about Margaret Cavendish. I couldn't justify using all of them.

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.

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.

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.
