Book One was dramatic, with Yellowstone blowing up. I got this book to find out how things go, but it is all left hanging. A slow decline, but will it collapse or recover? Maybe he has a dozen more books planned before we know.
Learning to adapt to colder weather, power plants having problems etc. in what seem to be very similar, if colder and with less reliable power supplies, circumstances as before does not, for me, engage the imagination. Things Fall Apart gives the impression of being just filler between the other two books with none of the sense of being in an alternate world I had hoped for.
