This novel focused on Faith NightStar, the most powerful F-Psy, and Vaughn, one of the DarkRiver sentinels. I really enjoyed the interaction between the two of them and the pack. I also like that we still got to see a fair amount of Lucas and Sascha; they didn't just disappear when we moved on to another mated pair. 
 The overall changes in their world continue and I liked that Faith's family handled her defection differently than Sascha's family. The Changeling are adapting and expanding and while they can be brutal it's generally justified and necessary.
