This is not the first book in the series and it was evident right from the start. The book presumes that you already know the characters, which you would do if you had read what goes before, but if not then it is a difficult book to follow.
When I have read series before and inadvertently started on the second or third book I have found that I can quite easily pick it up as the author will gently recap some of the salient issues. However Slaughter didn’t do that so I was making up my own back-story as I read. The trouble with this was that I didn’t really get to know the characters and therefore didn’t care what happened to them.
I never really got into the book so after about 70 pages I gave up and didn’t finish.
