" Scalzi is quite good at building up a situation until you just can't imagine how it's going to be resolved without everyone dying. He's still quite good at that in this book and I enjoyed this ending more than in the other books in this series. Having said that, I gave this book three stars because it often lags. Sometimes the dialogue turns into philosophical musings (not in the good way) or long debriefings of the reasons behind some action, such as the conversations between John Perry (he's back!) and General [insert one of three names here]. This kind of thing, if overdone, irritates me, because sometimes I think it was bleedingly obvious and we didn't need it, and other times because I just don't want to have a character's every thought process explained to me. Let the reader think about it. Let them debate with another reader why John Perry is a hero or a traitor. Leave some of it to be a mystery. "
