Weirdly the back of the book has the blurb from a different one. However, if you are familiar with the series, you would know that. The plot of this is interesting involving east European sex-slavery of werewolves and witches which was very violent.
Luna is still top dog (ahem) of the SCS with new love Will from the ATF (FBI) at her side. This was a well crafted relationship and is one of the real strengths of the novel - cousin Sunny and fellow cop Bryson hardly feature this time.
But, Luna was even more relentlessly irritating than in the previous novels, totally going off the rails, blowing open her stake-outs and ultimately and totally unsurprisingly getting kidnapped. This was attempted to be explained in terms of Luna dealing with her monster, but it was just so annoying for a long-term police officer. What it was doing was setting up later books, as became more clear towards the end.
Dmitri was back, and Luna now finds him just as irritating as before, which is quite refreshing to see in werewolf literature where the whole Alpha wolf and pack mentality dominance is pretty much a given in any book I have read. Luna also seems to be developing other talents - again an indicator of books to come, as is the title of 'Daemon's Mark'.
Oh well, I like Luna, I like Will, I like Sunny and I kind of like Bryson so I have no doubt I will be buying Number 6 in the series although I have to say that it's really the humour that keeps me interested.
