I've been reworking the basic map that will be coming with future e-versions of A Wind from the South. It'll be a while before it's ready, though, so here's a stopgap measure.
For those readers who use Google Earth, I've uploaded a basic placemarks file that shows the major (and minor) locations involved in the book. You can download the file at this link.
(And yes, I'm looking into doing something similar for A Wizard of Mars. We'll see how that goes.)
