This is not an "official" map. It's just the latest in a line of dozens and dozens of hand-drawn and computer-aided maps I've drawn over the last few years while writing the trilogy. I drew this one today, with so much snow falling outside we had to cancel a trip, so I decided I'd spend the time on a map. I was trying out a new art & design program, and didn't quite get everything to work right, as you can probably tell. Please feel free to use this as a rough guide for your own maps. There are no doubt some errors in it (for example I think the farm at Blue Hill is actually a little further east than this map shows. Also, the unlabeled river that flows out of the Wood and through the "n" in Bourne is the Bournewater).
The problem for me with maps & stories is that I love drawing maps and charts so much that I have to remind myself once in a while to stop with the maps and actually do the writing!
