This is the third installment of the series. I found this one a bit hard to get into to start, but once it got going, I enjoyed it. Mark has been in all the stories, and he is the focus of this one. He has found the heir, Pen, and falls in love. Their relationship is different than most but it brings out the best in both of them. Pen is sweet and wishes to go unnoticed. He tries to keep up a brave face when doing things he would rather not, but his heart is almost always apparent. The series has a lot of darkness to it but is balanced out by the HEAs of these M/M pairs.
I received a copy of this story through Netgalley, and this is my unsolicited review.
