I liked this book. There wasn't a lot going on (action/adventure wise), but after the last few books, that was good. The team gets sent out on a few assignments, and there is a bit of case-related tension, but nowhere near what had been going on previously. 
 Parts of this book were really hysterical. The way the team comes together and interacts with one another is gold, really. 
 We got a bit more with Seb and Hudson, and there was definitely some Hobbs family drama. I was pleased to see Rafe's story expanded. Even though up to this point he's been a read asshat, I felt there had to be a reason. His behavior was so over the top (especially when you consider Ethan and Seb and their family) I felt there had to be something more. Something he was dealing with, or trying to keep from his family (and perhaps he was trying to push them away), so I was pleased to see the glimpse of him and his brothers. 
 The ending, of course, was pretty intense, and opens questions that I'm sure will be resolved in book seven.
