From the author who brought you Machinehood, this is another nicely complex story about where humans fit into a future world that is ruled by alloys (i.e. sentient machines) and especially the overlap between their two cultures. A lot of politicking, some space exploration and a love story at the heart of it. Some really sensible and compassionate treatment of the question “What is a disability?” with a protagonist with sickle cell and an alloy who gets damaged. I loved the different ways the author approached these ideas and how there wasn’t just one right way to be a human OR be an alloy.
