For fluff, it’s got some really dark scenes. It doesn’t have enough of a plot to be anything more than fluff, though. It absolutely does NOT stand alone, so don’t consider reading this book unless you’ve read all that went before it — you’ll be hopelessly lost.
Sookie has changed so much over the course of this series that she is having trouble recognizing herself, and is troubled over it, with good reason. Having a main character change is good, and I’ll say that some of that change is growth, but I can’t say it’s all growth, or all to the good. (Can any of us say that, though, about the changes we go through in our lives?)
