Read this because it was one of the MM Group awards winners and I thought it would be good. I was quite intrigued by the dynamics of the MMM relationship in this book. 
 Although I find it terribly unbelievable, I like how the relationship was successfully built. I thought: some people are happy in polygamy, with the older and the younger wives becoming friends and allied, developing strong womances. Lots of unbelievable things are possible, though probably uncommon. 
 I have to admit I skipped most of the BDSM part, though I found the beginning of the first BDSM scene VERY well done. (view spoiler)[ It starts with the sub being photographed by the two doms, and they tell him how to pose, then it subtly evolves into a BDSM session when the next order is not a polite "turn your head left" but something like: "kneel!" with a dom voice.
