4.5 stars. Just a few personal thoughts. I really liked the mystery/thriller plot. There were twists and turns right through the book. Bran is more appealing and approachable in this series. I only knew him from the Alpha Omega series before this and was fairly ambivalent. I was struck by how much research the author must have done for this story. It was full of interesting details. I smiled to myself when I read about the black button, I thought only we knew about that. I'm really starting to invest emotionally in all the secondary characters. Usually I don't like love triangles but I'm fine with this one because it's not the focus of the story at all. Although I believe in book 3 Mercy eventually makes up her mind.
