That was fast! The issue has been resolved, and quickly. Now I just hope it stays that way. The new paperback cover is now available in all Amazon Kindle stores. Thanks, and sorry for the flurry of posts.
It's back for the U.S., available now, no delay in shipping. And something is happening on the U.K. site - at least it's listing a paperback, though it says they don't know when it will be available. I'll let you know when I see it's ready there. Sorry again for the trouble!
Sorry folks. I reported that the paperback edition of Paternus was available on Amazon - and it was, for the U.S., but not international markets. Now, for some reason, it is not available for the U.S. either. It has a listing for the U.S., with the new cover, but it looks like only used copies (which would have the old cover) are available.
I've been assured this is temporary and CreateSpace and Amazon are working to fix the issue - but it could be another 3 to 7 days. I'll report as soon as I see that it is available, both in the U.S. and on international Amazon sites. Very sorry for any inconvenience!
All the best,
