Still an excellent hard sci-fi story, but this one had annoyances the previous installments didn't. The viewpoint character for this one spouts way too much macho bullshit for my taste. Also, even though sexism and racism always were right at the front of the Lady Astronaut stories, the gender war here seems relentless and really tiresome. Also one of my least favourite tropes "I'm not going to tell my loved one(s) things to protect them" rears its ugly head; one of the reasons I enjoyed The Calculating Stars was its utter refusal to deploy poor communication as a plot point.

Despite occasionally grinding my teeth at the points mentioned above, this is still a very good, very hard science fiction story about living on the Moon. The plot is effective yet non-convoluted, and when things get nasty, you really feel the blows. Definitely recommended.
