Having read the reviews here, I expected a very good thriller! I'm disapointed. I had great difficulty in hooking up to the middle of the book! It's long, incredibly slow, and without thorough psychological analysis that could level the vacuum action! But since I do not like leaving a book in the harbor, I am compelled to finish it. Good also because ultimately the plot itself is rather original and interesting, but I think the author needs to deepen his writing if he wants to pursue this voice thriller. In any case, I considered buying the other French title but then finally no, I think it must first evolve in the way his characters search and intrigues and make a choice between the styles that considering bringing in his works.
