Dear reader, dear reader, before reading a notice, I think we need to get an idea of the kind of person who wrote: I am female, and I go on my 16 years. Now you can decide if you continue reading this comment, or else if you simply do not manage to identify with a teenager (you were yourself no so long ago ...). The main character is just a thirteen year old boy who leads a mysterious and exciting investigation but which gradually turns into a nightmare and takes this delicious tragic hue. The moments of suspense and pure anguish maliciously sprinkle this disturbing novel and a macabre promise whose scale and proximity will reveal at the very end of the story, when the panic and horror will in height ... Between Marina, Shadow of the Wind and Prince of Mist, I did not hesitate a second: it is definitely my favorite, I started after lunch and was forced to extend my reading until late at night to know the final outcome. 5 stars !!! Excellent!
