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 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'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 way I've talked about my research process is that it was like magpies. I was just sort of moving through all these books and when something shiny would pop out I'd be like, Ooh, I love it! and I'd pluck it out. It's fun to figure out how to use those bits you really love - like I'd read about gold shoes with cork heels. Obviously, Margaret would have to wear those shoes.

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'm not entirely sure what a historical novel absolutely has to be, but you don't want a reader who loves a very traditional historical novel to go in with the expectation that this is going to deliver the same kind of reading experience. I think what's contemporary about my book has something to do with how condensed things are.

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.
