Some folks love this book and I can see why - good continuity of characters, real peril, some world building I can see is going to grow with the series.
It is no The Martian.
There is little humour and the characters are universally selfish, which you can justify Is because their world is harsh and selfishness is rewarded. I found the women in the book caricatures from the 1990’s, and the protagonist so-so.
