I love some of the earlier Scalzi. Up until Locked In, he could do no wrong in my eyes. Old Man's War and Fuzzy Nation being stand outs for me. 
 This book? Okay, so, I DID like it, yes, but I had 2 main issues with it that ultimately dragged it down from the strong 4 star it should have been. 
 Alternating POVs. Now I don't have an issue with these in general when it's kept to a manageable number (and it was), but for some reason, and I have no idea why, I found it difficult to make the swap from the different storylines that were happening. Not normally an issue for me, but it was here, and I don't really know why. 
 Kiva. Shit character. Nothing else to say.
