The vendetta part of the story was far more interesting to me, which is good, because the bulk of the story was about the Remingtons trying to figure out how to deal with the thorn in their side which is Guy Preston. I thought the author did a good job of drawing it out and finally into the resolution. Not to give any spoilers, but the trick was to tie the law's hands so that it was up to the Remingtons to deal with him - without breaking the law themselves. I thought SJ McCoy walked that line pretty well.
We also got to see a lot more of Chance in this book, whetting our appetite for his story - which I understand will be a three book spinoff. Chance is a very complex character, and I enjoyed getting to know more about him. I don't know what his story is going to be about, but I'm quite sure I will enjoy it.
The four stars is entirely because of the way I couldn't get excited about the weddings. It has nothing to do with the writing, which is very good.
As far as content, I would rate this PG17. There is a bit of innuendo, and plenty of swearing, including f-bombs - though not too much by my standards. I don't remember any graphic sex scenes, although there is reference to it, and at least one "closed door." There is also some violence, both 'on screen' and off, and plenty of suspense.
