I decided just to finish this series off and it was a wise decision. Read this in a day and it was a very satisfying conclusion to the series.
This one is about change and abandoning toxic behaviours for new possibilities. Some decent speculation as to how a lunar colony could become a lunar state and what options that offers for exploring the solar system. Ofc, there is handwavium technology in here but that's a given for this kind of story telling.
The whole series is a recommend from me.
