This is an excellent book of adventure, where the action does not stop a minute! Panting and taking, there is no time to catch his breath. The characters are pretty cool, they are strong but not "omnipotent" and do not always come out by themselves, but need help. The amazing thing is that even if some details seem "capillotractés", a small author's note (which some have failed to read (on Goodreads), apparently), said that all the technical advances which it is in this book are real and already created. "Seek and you shall find", as the author says, citing Matthew. In short, it was exactly the kind of book I needed after the previous few disappointments. As for the "seen and reviewed" (read also on Goodreads), where I am still looking for my part I never read an esoteric thriller also pushed scientifically speaking, the books of Dan Brown are quite off the mark, although pleasant to read, easier, much easier than this one on all planes.
