Plenty of similarities to "The Moon is a Harsh Mistress" and a few to Star Trek: the Next Generation. Quite a few characters in this book, most of whom are fairly flat. The story was good, if a bit predictable. The science seems pretty accurate, but it's been a while since I read about colonies in space. Overall I enjoyed the story and will read the next one in the series. 3½ stars.
Despite the author being a woman of genre fiction, this is not one of the books I am reading for that challenge in 2013.
