Got a response from Night Shade Books: they would like to have my edited mobipocket version, but only for their own download site. Next to that, they asked for some advice how to produce proper mobipocket books. I guess I'll point them to this forum
If you ask me, this is a good sign: publishers don't deliberately put "poor" mobipocket versions online, it's more a matter of know-how (or better:
not knowing how)
I'll edit the first message in this thread to remove the download, anyone who wants to download an "enhanced" version should go to the
Download site from Night Shade Books for Butcher Bird. I guess that in a couple of days, a better mobipocket version should be available for download on this site.
