Yet another great novel by Briggs. We get to continue to follow Charles and Anna as they hunt a serial killer targeting Fae and Were's. Since the wolves have come out to the public they've had to be even stricter with discipline and it's wearing on Charles - luckily Anna manages to get Asil and Bran to pay attention and give Charles another duty to help him take his mind off his duties and put things in perspective. 
 The ending was absolutely nuts and I can't wait for the next installments in both this and the Mercy series' as (view spoiler)[ the leader of the Grey Lords has just majorly changed the game. (hide spoiler)] 
 The only thing I thought was weird, and I could be mis-remembering, but I though that since Charles was a born werewolf he didn't experience the change the way the others did; that is was more magical and not painful, but there was a lot of talk about the pain he was going through to change.
