I got a nice email from my editor today; the dust jacket received final approval last week and so it is being "finished off" now. The books should be shipped from the printer around the middle of this month. I had wondered why the cover image hadn't shown up on any of the online bookseller sites yet. Now I know.
And remember, the book is already available for pre-order from all the online sites. The list price for the book is $24.95. So far, Amazon has the best deal that I've seen: $16.47, plus another five percent off if you pre-order now.
