I used to be really interested in history and spent a goodly amount of time wandering around in old book stores. Not the modern ones that sell nothing but new stuff. The ones that had nothing but old stuff. Anyway, I found an old history text book, "The hostory of the world from 500BC to 1945". I read almost like a novel. The various things that would happen in one place would be carried through to show the modern results from it. Kind of like the old TV show "Connections" that should the affects of one thing on the future things. It was pretty tattered, I read it regularly just like you would a very good novel. Some horses A__ stole it from the barracks when I was in Iceland.
