In this third installment of the series, the FBI are investigating a series of murders, and they have requested the pack's help. Anna is concerned about Charles because his job as the pack's enforcer is getting under his skin in a way that no one seems to notice but her. Their presence on the investigative scene enables Charles to use his skills in a more constructive way, while giving Anna some insight into the ghosts from Charles's past that are coming between them.
As a mystery story, I found it lacking in the complexity I have come to expect from Briggs' novels. I pegged the perpetrator pretty much from the moment the character was introduced, and I also found some of the plot elements just a bit contrived. But I enjoyed the way in which the mystery enabled Anna and Charles to work out some of their own issues, and it worked great as a backdrop for the further exploration of their complicated relationship.
I still prefer the Mercy series, but this one does have its charms. I will certainly be looking forward to continuing with the series.
