Thanks for yesterday's comments! They were very interesting, especially since I was leaning in the same directions. But I finally chose to read John Waller's book, which turned out to be something different than what I was expecting. I'll not give away the story, for the sake of those of you who might also want to read it. All I will say is that Waller's writing style kept me engaged throughout and, as good nonfiction should do, caused me to reflect more deeply on somewhat similar and more contemporary "dancing plagues."
