Shaun's violent tendencies rang true for me. Sure, everyone in this world has lost *someone*, but it was very much telegraphed in the first book how much damage it would do for Georgia to lose Shaun or vice versa, because that's not just losing someone, it's losing *everything*. I was shocked by Georgia's death in Feed, because it's a fairly standard convention in fiction that the point-of-view character survives. Grant abused that trope to great effect, and I was impressed with the storytelling once I got over my initial dismay. I like it when a writer can surprise me. The story "Cold Equations" which is referenced in this novel can be read here: http://www.spacewesterns.com/articles/105/ Worth checking out even though Shaun's explanation spoils the ending.
