This book was disappointing. The opening chapters seemed to be setting up a Crichton-esque adventure-thriller, but then the narrative went on to flatline for extended periods over the next 200-300 pages. It felt like the authors were overly eager to share their research, and they used the story as a vehicle to accomplish that, instead of using their research to flesh out a compelling narrative. Too much emphasis on archaeological and cultural obscurities, with too little focus on tempo and plot. Two stars.
