I read this book because I've loved the rest of the series so much that I've been dying for this book. It finally came and I just couldn't wait. Keri Arthur has become one of my favorite authors and I'm thinking of trying some of her other series'. 
 We don't have too much in the way of a hero. This is about Riley Jensen and her life as a Directorate agent (something like FBI for nonhumans). She's half werewolf and half vampire, which I know you're thinking isn't possible but she explains it. We also delve into her personal life in the form of family and love. 
 In this book, Riley is again tossed into a mystery when Vampires are being beheaded and woman are dying of what appears to be nothing. As Riley has discovered, two cases like this tend to mean a link and she starts piecing the puzzles together with the help of her Directorate team-mates. 
 I would say in the past Arthur gave us more in the way of Riley's friends and family. Rhoan (brother), Liander (brothers soulmate), Cole (colleague), and Sal (colleague) are barely in the book. You would think that alone would upset me. But it doesn't because their brief time in the book seems natural for the most part as Riley barely had time to stop in pursuit of bad guy and trying to fend of a soulmate that seems psychotic. 
 Arthur has; as always; made this fast paced, mysterious, hot, sweet and sad all in one book. She did a wonderful job that leave me telling those who like vampire/werewolf stories that you should read this because it is one of the best I've read in a while.
