I enjoyed this book. For the most part interesting and fast-paced. Bogged down in a couple of places, but nothing too annoying. Similarly a couple of plot holes, but nothing so gross as to affect the overall story line.Agent Pendergast is an interesting character, but more a collection of affectations than a fleshed out person. I'd have enjoyed it more if the authors had spent a bit more time developing his character and letting us know what makes him tick. Maybe they do in the other books in the series.The story's good - part "Silence of the Lambs", part "X-Files". Some nice plot twists and atmospheric settings. It would make a good movie.
