Thanks! I'll check the Postwar next week or right after I'll visit my family. Durant is going on my reading list regardless. The Dark Ages are among those periods that always seemed like something that I would enjoy visiting from a different perspective than warfare. Just, again, it's one of those things that high school can somehow make boring. Your review did intrigue me enough to even ask the previous questions so kudos.
So just to be clear: this isn't "a book" we're talking about.
I know, it was more of a mental shortcut on my part. Same way I call LotR or Feynman's Lectures as "a book" instead of something more appropriate.
