The audiobooks appear to be available everywhere.
The ebooks appear to be available everywhere but Australia/NZ. Anything that can be done from here is being done — I’m really, really sorry because I honestly love my Australian fans T_T.
(Where by celebrate, I mean that I realized I actually needed a bit of a visual guide after all this time, because I am terrible at mapping, and at reading maps. I am one of those adults who, if they must make sense of a map, must orient it so that the street that I’m standing on is also in the direction I’m facing, which frequently means the map is upside down to other people. This causes some confusion. My orientation, in the world, is Right-Left. I know most people prefer actual compass directions, but… they don’t translate well for me. Sadly. All of my maps of Elantra have been word maps – indicating where places are in relation to other places. In a wiki.)
ETA: Mati Demers has offered to sell print maps to people who are interested.
