I didn't like this second book nearly as much as the first one. There is more philosophical dialog than action, though there are chase scenes and threats to confront. As robots gain emotional complexity, they experience a sense of instability, but I'm not sure if that's good or bad even though the older robots think the increase in ideas and making personal choices means they are evolving. The plot can be hard to follow, and the motivations of the different characters are not always clear. The human characters are all viewed through the perceptions of the robots, so there are gaps in understanding them too, which I don't mind at all. But, the ending didn't make any sense to me either, which isn't fine. There will either be more books in the series or not, but there should be more of a distinct ending to this book. I was left wondering what I'd missed, so I went back a few pages and tried to figure out if I hadn't remembered important dialog, but I hadn't missed anything. This is the first book by Sean Platt and Johnny B. Truant that I haven't really enjoyed.
