Relentless Moon

The Relentless Moon, Mary Robinette Kowal. Well, I think I am officially recategorizing these as a good series I didn't like the first book of rather than a series I'm not into (previously), because I enjoyed this quite a bit, to the point of not wanting to put it down in the second half. Spy-vs-spy action grounded in space realism, totally into it. Thank you to the Hugos for getting me to pick up a series I had written off after the first one.
