These days I always seem to be working on a lot of things at once, so “next book” has multiple meanings. There’s the next one to be published, which I finished writing several months ago and is now making its way through the publisher’s production process. There’s the one I’ve been asked to write and given a title for, but I’ve barely started to think about it yet. And then there’s the one I’m actually writing at the moment. That’s the one I’m talking about here. There’s a clue to its subject matter in the research material pictured above!
