The Cartographers

I threw the penalty flag with emphasis, several times during the second half of the book. How can you whip out something magical in the plot and not give any infrastructure to its existence?

How the heck do these places come into being? According to the plot, they just are and the characters, I have to assume, are ok with that.The author mentions individuals can recognize these places when looking at a map and yet give no details as they do it. Is it something about these individuals? Their mindsets? Comparing 1 map meticulously to another edition of the same map? What?

To the positive, I'll say I've not run into a plot involving map mysteries so this was interesting, and the audio narrator does a good job of making her character voices distinct enough for me to catch when there's a shift in speaker.
