Judd has interested me since the first book. I knew he's be an interesting character and I was not at all disappointed by this story. It was also interesting to get more detail on the Psy's from Singh as she developed the Arrow assassins in this book. It was also nice to be introduced to more of the ShadowDancer pack. We got to know a few more of this pack, including the Alpha, Hawke. 
 Brenna is also a good character. I like how strong she is even after her attack by the Psy in the previous book. Brenna has been through a lot and the idea of a relationship with a man seems unlikely from the beginning but you soon realize that Brenna believe it is the only thing that will help her overcome. Brenna clearly needs to know that she can let someone love her before she can start moving forward. I think it was a nice touch and I've very glad that Brenna didn't die but got a happy ending. 
 I'm very curious about Riley and Andrew. I think they should have a good story in their future but this book only made Judd's family the Laurens more interesting to me. I adored the littlest girl who is apparently more like Judd that the others and I'm interested in the strange relationship Hawka and Sienna seem to have. 
 Singh is doing well and keeping her readers interested.
