If I read this book with pleasure, I must say I am rather reserved on certain aspects of the plot. The difficulty of this kind of novel, whose starting point is both ingenious and mysterious, is to solve this intrigue as brightly it was initiated. If some answers are satisfactory, the fact remains that Glenn Cooper had to appeal to a fantastic element to everything clicks into place and this has somewhat offset the pleasure of the enigma to me. The style meanwhile is fairly ordinary and customary to the genre where the background is more important than form.
Three stars therefore, the whole being means: some brilliant ideas but also some shortcomings in their final development.
