1) Yep, they are able to catch me by surprise still, and even better, do it by meeting my expectations on one hand while utterly subverting them on another.
2) It is a bad idea to read two of them in a row. It’s not that popcorn isn’t still delicious every time you get a tub of it, it’s that you fail to get the proper impact if you have it daily.
3) Man, life really is nasty, brutish, and short. These are the good guys, and they usually try their best to help the most people, but noble self-sacrifice? Playing long odds in the hopes of saving a few more? None of that. They help when they can, but if they decide they can’t, that help ain’t coming. On the bright side, they do a pretty good job of staying alive, and they’re almost never the aggressors. But heroes? Nope.
Also, though I didn’t learn this from the specific two-in-a-row circumstances, Latitude Zero taught me that this author and/or stable of authors is really quite good at recycling villains. And getting me to empathize with them, no matter how minimally. I know I keep praising this series, so I should make a point of explaining that it’s not that they’re objectively good. It’s that they’re a post-apocalyptic sci-fi series that so dramatically transcends the limitations of the men’s adventure shelf, and in so many literary and social ways, that they are objectively Not Bad. Which is wildly unusual if not unique in the annals of that shelf, and results in my getting to read a never-ending series that is dialed into my specific proclivities.
It’s like that time when the soap opera I randomly chose to watch from the beginning as my first ever soap opera turned out to have witches, talking dolls, and portals to hell opening up under peoples’ homes. Nobody could have predicted that something so perfectly aimed at me would ever exist! Much less that I would trip over it.
 Because I was camping in the desert and didn’t want to a) run out of books nor b) destroy my delicate electronic devices nor c) bring a book whose physical form I would be worried about.
 I did not. So that worked out pretty well!
