This could have been so much more. I think that the (in my opinion, flat?) descriptors of non-white people in the book stuck out to me - despite Sethu's character having a considerate amount of depth - and made it hard for me to relish the ending of the book. However, I do see how, ignoring that, this story's appeal. A prime example of deployed technology that didn't have enough foresight and the (repeated) reminder that you only need one mistake to have everything crashing down definitely rang home (and felt annoyingly and boringly pale).
