While I was prepared for the degree to which this book was an indictment of our public education system, I was unprepared for the degree to which it's an indictment of pretty much our whole society, including education, national government, mass media, etc...
I have to admit that I'm really still digesting the implications of the book and will probably need to re-read shortly.
I enjoyed the beginning and middle immensely. Walton does a great job of characterization with Mor and with capturing the nature of a young SF and fantasy reader.
The end felt rushed and disappointing though.
While decent enough, I was generally disappointed in The Ghost Map. The story is certainly compelling and Dr. John Snow's pursuit of the early science of geoinformatics in pursuit of defeating cholera is a great story. But Johnson fails to wrap up the tale in a satisfying way, letting the final third of the book drag on indefinitely.
