Ok, so, the good:
This is an attempt to write a fictitious, in-universe academic history text about the events of Star Wars. It touches on issues of historiography, bias, and ‘Great Man’ history vs structural causes. It doesn’t just cover the events of the films, but the underlying economics, social dynamics, and political background of the empire as portrayed in the movies. It paints a realistic portrait of how a fascist state operates in a galaxy far far away, while still acknowledging the fact that said state is ruled by an evil wizard.
I think this is very neat, and potentially an awesome way to get students or people uninterested in the art of historiography into understanding the process of how history is written. I also think it does a good job trying to explain or rationalize the very dumb plot developments that have happened under Disney’s watch.
The not so good:
I think the book would’ve worked better if it was further removed from the events of the films. The author mentions interviewing Rey, and directly quotes Luke Skywalker at various points, and to me that takes away some of the magic. I was hoping that the author would be writing from a vantage point of ignorance about the more personal narratives in the movies, and maybe would dismiss the supernatural elements altogether. But there just isn’t quite enough of that sort of “unreliable historian” in the book. Largely the events of the films are depicted accurately, with only things the narrator couldn’t have possibly known omitted.
It seems to me there isn’t enough of that ambiguity, that “well source A says this but B says this” that you see in, say, George RR Martin’s Fire and Blood. Why does the author know that Vader is Anakin Skywalker - that would’ve been a cool thing that the readers knew but the author didn’t.
Finally, the book is seriously hamstrung by its requirement (which I assume was a corporate mandate) to frame all of the events as leading up to Episode IX, and to recontextualize everything as being a part of the Emperor’s “grand plan” to do whatever nonsense happened in that movie. And that kinda sucks, because it requires contorting the rest of the book to ultimately be about a movie that very few people liked.
