I know that some love maps, some are indifferent, and some dislike them. That’s as it should be.
I personally like maps, because I’m geeky that way but also because I process information both visually and kinesthetically, and thus maps make it easier for me to negotiate certain kinds of plots. Yet with other stories, I don’t even think of wanting a map. I wonder if there is a kind of story that seems more to benefit by a map while others just don’t have any call for them.
There are narratives in which there are things about the world you can’t learn from the story but which you can glimpse if the book includes a map, so in that sense a map can add a bit of extra dimension to a world. One of the challenges of writing the Spiritwalker books in first person is that there is a lot of information about the world that can never get into the narrative because it isn’t something a) the narrator would reflect on much less know &/or b) that is necessary to the plot.
