I liked the way this book started but I had trouble finishing it. To me it felt liked it dragged towards to end. A few unnecessary scenes that I could have done without. That is a pity because I quite liked the 2 couples in the book and the way the story developed.
As for the complainers about unrealistic BDSM scenes; there is a disclaimer in front of the book telling us that it is not realistic and not according to standards (safe sane etc). Guessed those people missed it. So it is unfair to complain about it and therefore rate this book down.
