Personally, it was not the one book in particular that was/is of interest. The geoban was what annoyed me.
Anyway, I got an answer from ms Rebecca Gardner of "The Genert Company" just now.
She claimed that for some reason she hadn't received my first mail but still replied to my last one.
A fairly generic answer, but she gave me the UK publisher (Century), so I'll send a mail to them as well.
I'll keep you informed.
