Dark Knight by J. L. Beck was a must read for me when I saw it was a dark bodyguard romance. I am all about the bodyguard romances and the fact that its dark romance made it even more of a need. I must say, I was not disappointed and the dark romance brought an element to this book that really brought feeling to the story as the characters are forced to deal with trauma and horror that has steadily eaten away at who they are, resulting in shells of the people they once were.
