This story sucked me in from the first pages. I could have read it through without a break if it weren't for other everyday obligations (such as family and food).
I enjoyed meeting FBI Agent Ruth Warnecki as she explored Winkel's Cave. You could forsee right from her rescue by Sheriff Dix Noble that a relationship would develop between them.
We are also introduced to FBI Agents Savich and Sherlock, who are investigating their own twisted mystery.
I enjoyed the interaction between the four law enforcement officers. Lucky for me the three FBI agents have been featured in previous novels, which I will be on the look out for. You can check Catherine's website for a complete listing of her books.
