I found this book a little better than the last. Singh picks up the story and the characteristics of each person in this book a little easier. We start learning more about the Psy and the Changelings. In the last book, we discover the existence of the E-Psy classification which was thought not to exist. Now we learn more about the F-Psy (Foresight). 
 Singh developed Faith's character well and while I disliked the frailty of Faith it was more a physical and emotional frailty rather than one of spirit or heart. This made Faith interesting. As did a discovery Faith made that makes reading further into the series seem promising. 
 Vaughn was intriguing in the last book (though Dorian is still very intriguing) and we get to see that Vaughn's close to the surface jaguar is fun and extremely possessive but not in a bad way. He just knows what is his and is very willing to keep it safe. 
 I do feel like we didn't get to know enough about the characters because of Singh's murder story and the development of any Psy becoming emotional (they suppress their emotions). I feel like both characters did a look of development on their own without really exploring the depth of their feelings and connection to one another. Still the story is compelling especially since we have a continuing story about a society that is corrupt and needs to be taken down or brought back to emotions rather. 
 While I think I enjoyed this book more than the last, I think it had more to do with the interest in the couple rather than the over all quality. Still the series is worth a look.
