Bernard Werber revives the investigation fantastic novel, to my delight! It embeds several frames which inevitably end up crossing, he adds a pinch of scientific news, it sprinkled with a touch of adventure, he made numerous references to his other works and multiplies the winks to his readers . We find joy with his world (or rather our universe, through his own eyes). I have always appreciated this capacity he has to know to germinate a credible scenario in a different difficulty universe. I could write tons, but if you still reading this review, you will understand that I loved the book! I recommend it!
