This was awesome. It's probably the best book in the series. Some events were completely unpredictable, which was a joy. It also got me really hyped for the conclusion. Fantastic.

When Amos was killed I was pissed. I was thinking you can't kill him like that. What was he even doing there? Someone needs to be his moral compass. He knows that. Why is he off on his own? Then it finally clicks that the repair drones are the dogs from Strange Dogs. Not like Amos being a half alien is what I wanted but it makes more sense than shooting a great character in the head. If he had been actually dead this would not have been a 5 star read. His death just wasn't spectacular enough to be his end. 

The other big character moment that got me was Bobby's death. Seeing it from Alex's perspective gave me goosebumps. Super emotional and a great visual to picture her as a valkyrie.
