I did enjoy this book; the concept is great, the pacing builds steadily, the plot well structured. There is much to like. The slight downside is the villain is somewhat predictable, but that doesn't detract much from the story.
The concept of the "lock in" to the victims of a virus and how they cope with living in artificial / remote bodies is brilliant. To me the scene setting and backstory was excellent. I would very much look forward to this becoming a series. Well done mr scalzi
