Each novel takes on a life of its own, so much so that authors sometimes have trouble staying on top of everything that goes on after the release date. Here are some examples.
I was aware sub-rights for The Penny Tree had been sold to Quebec Loisirs, the French Canadian book club and that they planned a big push for this fall, but until google alert picked it up I hadn't seen the new cover they'd come up with (which I really like because she's leaning against a tree and the English title of the book is after all The Penny Tree).
In addition, here's something you may not know. I might never receive an actual copy of this version of the book. Sometimes I do, sometimes I don't. Authors have to push hard to chase down copies from book clubs, and in some cases I've simply given up, joined the club, and ordered a few copies of my own book for my personal library.
Stuff like this happens all the time. (ie., audio rights were sold for The Tin Box in Denmark, but I didn't find out until I read it on a royalty statement). Initially, when I was first starting out, I was appalled. I was the author! Shouldn't someone out there be communicating every detail with me, including the release of a new cover!?
Now I just laugh. I am, after all, only one fish in a sea filled with fish, and the publishing industry is in a constant state of flux and movement. Everything aside, I'm just grateful that my novels have been included in that movement.
