So, sometimes you just get to the point of needing to start reading when you can't wait for the next season of a show. So I'm reading the fifth book in the Expanse series. And let me tell you something, I was shocked at how simply written it is. I was expecting Tom Clancy and got Richard P Henrick. The show provides characters with more nuance and stuff below the surface, the book just kind of blurts it all out. It is definitely a good read so far, but it is much more of a simplistic storytelling than I had expected.
Did you start with book five, or have you read the entire series?
I find that in a lot of book series, the later volumes tend to start with a quick character sketch for the main cast as they pop up, presumably for readers who have had long enough between books to forget, and for people who are starting somewhere other than book one. This tends to make the first few chapters of each sequel a little bit simplistic, as it broad-brushes stuff that was more subtly dealt with in the previous novels.
I haven't seen any of the TV show, so I don't know how closely it maps to the books; But IMO the books are excellent.
