I actually enjoyed this book quite a bit, despite my criticisms. It was a quick and compelling read, and I liked the protagonist (although she tended towards the too perfect--a few flaws would make her a lot easier to relate to). What it was lacking, for me, was a lot more sense of place and culture. The colony was descended exclusively from Russian settlers, but we don't see any of that in anything but the names; the book explains that the people don't relate to their Earth ancestors anymore, but they weren't so many generations removed from Earth that every trace of any traditions would have been erased. As well, the entire planet is underwater, and thus almost the entirety of the action takes place underwater; but outside of the very beginning of the novel I rarely got a real sense of that. A little more richness would have gone a long way.
