This book was pleasant and a lot of fun. It wasn't quite what I expected from the author of Claimings, Tails, and Other Alien Artifacts, because it was more light-hearted and less intense. But it was funny and hot, and I had a great time. It is BDSM, but of the sweet, fun type - it might annoy true BDSM fans, but it went down easy for me, since I am not such a fan.
I was a bit concerned about how the author portrayed the Appalachian setting - I wondered if it was too stereotyped and insensitive. But I came to feel that the author knew these people and was writing with love. I suspect the weirder aspects of the culture were more her parody of how people regard "hillbillies" than a parody of the culture itself. Terry Pratchett used to say that his books parodied people's attitudes about countries (like Australia/XXXX continent) rather than the country itself, and I got the same feeling here.
In any case, the story was a fun easy read, with lots of humor and hotness, and the ending left me with a warm, happy feeling.
