It shouldn't be long now, at least for those of you in the UK.
The books are back from the printers, and my editor at HarperCollins was kind enough to overnight me the first advance copy. I am holding it in my hands right now. There are many rewards in being a writer, but none as sweet, I think, as opening the first copy of your latest book. Makes it all worthwhile.
The British bookshops should be getting their shipments in a week or two, I would estimate. Just when they put the copies out, I couldn't say.
