It's still a good opus of this series of thrillers Freemasons. It is quite easy to read because of the very short chapters. It is quickly taken by the scenario and there has excellent basic ideas for constructing the plot. So all this is very pleasant and we are happy to find Antoine Marcas, Commissioner. However, I issue a little flat. The division into short chapters somewhat conceals a certain length (when Marcas is found in New York, a very credible action phase follows some procrastination). In addition, some aspects could have been better developed (the end of the "adventure" of Nicolas Flamel and especially the operation of Aurora). So for me, this is not the most successful but it is a good novel and all this is a matter of taste.
