I love this series. It's a perfect blend of mythology, contemporary times, action, story, and characterization. Plus I love Hearne's humor, sometimes snarky, sometimes dry, and sometimes just silly stupid but always smart. 
 Having said that, this installment is lighter on action than most of the previous ones. When we get action it's intense, frightening, and thrilling. But in between we get lots of thinking and talking and narration. We also don't get many scenes with both Atticus and Granuaile as they spend most of the book apart on separate adventures. The story is told in alternating POVs - Atticus, Granuaile, and Owen, Atticus's teacher and mentor. 
 Owen is cranky, cantankerous, funny, and more objective than Atticus. As you if you've been reading the series, most of his problems are of his own making and Owen has no problem telling him so. Owen is interesting and I like the perspective he brings to the story; his interactions with the werewolves and the modern world are a hoot. I assume we'll be seeing more of him. 
 We finally find out who is behind the attacks on Atticus and why. There's death, betrayal, and heartbreak, and I cried. Politics suck. While this wasn't one of the more enthralling entries in the series, it moves the story along and sets up the final battle. I can't wait to see where Hearne goes next with this series.
