The Relentless Moon

 This time we follow a side character of the Calculating Stars. She is a pilot that is also the wife of a senator. She's on the moon as the colonization keeps on working. There are issues with a terrorist faction on Earth trying to stop the space program, mainly through sabotage. She has to uncover the culprits on the moon. 

 It's again an entertaining continuation of the books. It delve a little bit more into the issues of having space colonization ( mainly the fact that not everybody on earth can be saved by going to space)
