The problem books 4 hands is to find if not harmony, at least balance between authors: too violent, too graphic, outrageous characters ... these are the problems when two authors of thrillers must work together. The story is original, the treatment is questionable. Indeed, many clichés to finally give birth to a series of fantasies in the form "and if I could do whatever I wanted without being punished, without any consequence to me, would I do good or evil?". Halfway between an episode of GTA and the life of Faust, the main character will use the powers of a mysterious typewriter (ink) to weave a very creepy and well abominable vengeance (the blood). The discovery of its powers is not even funny, impossible to identify with the character or understand what it does, to share his actions and decisions. His enemies are not choirboys but honestly, they do not deserve the end he "wrote". A legal saves? Well going to the end of the story to know the answer. As this is a new in paperback, price saves the book so to speak. But do not buy it because you like the books of Franck Thilliez, you would be very disappointed. In the kind "I do what I want, I can have it all," I recommend the new Robert Louis Stevenson's "The Devil in the Bottle" where the holder of the bottle can see all his wishes carried out, on the express condition of dispose of the bottle in time if not his soul to the devil to be forever ...
