Well, Higgins improved on his previous book by getting Dillon more involved and ending his time with an annoying family.
Unfortunately, this book eliminated an important main character, had one of the villains that Dillon seemed to have killed in the previous book survive, and had an (understandable) mopey Dillon sporadically involved in the story until the end.
Hannah Berenstein was the heart and soul of the Ferguson team. While everyone was planning and following through with killing people, Berenstein was the one that would say, "Wait a minute -- is there a better way to handle the problem?". Sometimes they listened to her, sometimes not, but she always made them think. Hopefully, Higgins added back a similar type of character to his Dillon stories. Plus, she had deeply hidden feelings for Dillon.
Dillon, on the other hand, he hid his feelings for her, but not very well. He was the one always flirting with her -- and it almost worked sometimes. Plus he felt responsible for her death. Thus, his mopeyness. That was no excuse to have him less involved in the story.
And the villain that survived? Well, she was only a "moderate" villain, if there is such a thing. She was on the bad side of the ledger, but by the end of the book, she allowed herself to work with the Ferguson group.
The book was just a downer throughout and had no spark until the end. I hope for another rebound in the next story. Rated it 2.5
