I enjoyed the mini-adventures where they were under the gun to get the task accomplished and the infighting/competition between Jack Jr and his father. I also liked that Jack's team included two teenagers who helped in ways the adults couldn't. If you suspend your belief system, this is a wonderfully exciting book. If you don't (or can't), then you will get bogged down in the impossibilities and probably not enjoy this third book in the Jack West series.
I did find it over-the-top at times and simply impossible but I liked the team of the good guys and when they pulled it out of the bag each time I was glad. So I did enjoy this book though it did get very religious at times. I really don't remember the first two books in the series being as wild and improbable as this one but maybe I'm just misremembering.
This is the 2nd part of the story started in the Six Sacred Stones. This book was action driven and fast paced. Every time, I relaxed and thought things were under control, something new happened. The story kept me guessing, shocked me in places, and I couldn't wait to see how it ended yet I didn't want it to end. Reilly threw in fascinating ideas of historical figures and as a reader you didn't really know what was true or fiction. Great read.
