Re Bujold: Yes, alas! but if you stress the issues covered, might they give it a go? But The Mountains of Mourning should indeed be a good lure.

Thanks for that info about Winterfair Gifts. As someone whose most exotic form of on-computer reading is PDFs (which I convert to rtf/doc files if I can, because they're invariably quite difficult, ie far more difficult, to read) all those formats sound dismaying. Must look into it, though - obviously no other solutions!
