It's a fair enough question to ask what a best-selling, Pulitzer finalist author (for my 2017 book, Collector of Lives: Giorgio Vasari and the Invention of Art) and finalist for the Digital Book World awards (for my 2018 book, The Museum of Lost Art) is doing on a site like this. The answer is that my interest in projects and productivity far outpaces the publishing industry. Through my agent I publish a book every year and a half or so, which is about as much as the market will allow a single author not named Stephen King or James Patterson. My books are critically-acclaimed and covered everywhere, from the New York Times to the Guardian to NYRB and beyond, but a quicker publication pace is not recommended than what I already keep up. And so I'm happy to work with other good authors, to help them through content editing (I'm a specialist in preparing winning non-fiction book proposals) and ghostwriting. It keeps me fresh and exploring new fields beyond my areas of expertise, helping interesting people. I've been teaching the mechanics of how to become an author for many years (how to get an agent, how to write a winning book proposal, how to navigate the publishing world, how to convince an editor to commission an article), which is rarely taught, and I'm also happy to share this knowledge. You're welcome to be in touch if I can help you in any of these ways. I live in Slovenia (believe it or not), but this is no problem in terms of collaborating, as I've helped authors from around the world. I'm happy to help you, too.
