Mercy was a book I was so highly looking forward to. What we see in this book here, is self-discovering in BDSM and the heroine being a dominatrix and the hero being naturally submissive. This was quite unique, I do love this type of dynamic, because one we just don't see this too often but we also see how the BDSM aspects of the relationship really help the hero and I was so intrigued by this one here. I will say that this wasn't quite a five-star read or even close to one. But I did enjoy seeing these two together. I also liked the way that the forbidden them was written. This is a story that is quite a page turner, I literally stayed up till 2 AM reading this book, so it was highly engrossing, but i just couldn't quite connect to certain elements in this story. I didn't quite understand why they kept their relationship a secret for so long, I mean I understood but I do think it was dragged out a bit too much. I am curious to see where this author will take the series. I wasn't a huge fan of the plot device for the big reveal of them being together. So while I understand why the author used it, I just wish that they had come clean with their family and friends earlier and been more pro active about it.
