I really liked this book. I liked the premise and I liked the world building. Not sure if I will go on to book 2 just yet. while the book was enjoyable the story seemed choppy to me. we started off with Duncan flirting with Callie and Callie secretly lusting after Duncan. Next thing I know they are making out in Valhalla. I was also confused as to why the "high bloods" didn't consider themselves human. and I always roll my eyes at the whole Maury "He IS the father" situations. It hasn't been done right in a very long time. The difference between the sentinels also wasn't very clear or why it was that way. I did love Duncan's personality. He was alpha but knew when to stay in his lane. He had the sweetest ways of showing Callie how much he adored her. I loved the parts where he'd kiss her hands, neck, face, and lips all while telling her what he'd like to do to her.

 I like Jim Frangione's performances but when an author starts calling their men "males" and their women "females" and then on top of that toss in the word shitkickers I can't help but flash back to the Black Dagger Brotherhood. Face it authors, JR Ward has killed Jim for any of your stories unless you steer clear of those key words Mrs. Ward has beat to death in her own books.
