This book is very long and very dense, but I'm inclined to say that it should become a text book for middle schoolers who are learning how to do research and write papers on what they learn.
I discovered that there's a lot here that I learned to do haphazardly and instinctively, but it would have been helpful in school to have more of a method to the approach.
There are three stories in this that don't make me want to buy copies of the book an burn them. And those three stories range from mildly interesting to modestly intriguing.
But the language and composition are good. The characterization is strong... assuming the author intended to make most of the characters loathsome and small.
The value of this book is as a distillation of reporting spanning the last 10+ years of US national politics. If you're looking for bombshells or new facts, then you're likely to be disappointed. But if you're looking for something that will connect the dots between the sometimes seemingly disconnected events, this is a great review of recent history.
I also appreciate that it isn't a partisan screed against Trump – although his supporters may see it that way. The author calls out Trump's strengths and abilities in plain, unapologetic language, just as he does Trump's flaws.
In typical Stephenson fashion, this book is overly long. But instead of enjoyable digressions into scientific or philosophical topics, this contains long recapitulations of ancient mythologies in a stilted tone and jarringly incongruent language.
It's fine, but far from my favorite Stephenson novel.
