If the first book was an exploration of AI and what would happen, and the second book was a meditation on morality and what makes someone a good or bad person, then this last, grand finale linked it all together to paint a portrait of war and what it does to people, and that it is most definitely not black and white. This whole trilogy is about what desperate people in desperate circumstances do, whether that’s being stuck on a frozen rock or having to rely on a (previously) murderous AI to save the Universe. The one thing I was kind of craving more of was Leanne Frobisher’s story, I was a little confused about how she got the point that she did, but maybe that’s addressed in the novella. All in all, I think it achieved the aim of creating a wide spanning, multi-character and multi-media picture of what death and life in a technologically advanced world would look like, and it was scary, but it also made me feel hope for the future.
