While reading this book, I was surprised at every page. I don't want to say too much. because I'm afraid it might be a spolier for those who haven't read it yet. An ignorant scientist. Murders along the migration route. So why? A book you can read with excitement. I definitely recommend it.
It also has a french made movie. But it was very bad to adapt such an exciting book to the cinema in such a stable way. I could only watch the movie halfway. The choice is yours. Have fun.
