After publishing 17 books, I’m no stranger to the publicity campaign. In my no-name days, my publicist would purr that my novel’s release would be ‘review-driven’ – which decodes: ‘We don’t plan to spend a sou on your doomed, inconsequential book.’ By contrast, as we’ve seen writ large with Prince Harry’s Spare, your volume can be cast upon the public waters as not a mere object but an event.
