The originality of the concept is the alternative ground (but not required for understanding the plot) between the book and mini-videos on Internet (called "cyberbridges, viewing on level26.com) that complement the written narrative. For example, one chapter ends: "He put the USB stick in his computer" ... and the book tells you: "To see what the policeman's see, open the link # 3" and the video viewing the officer in the story you are "available" in pictures on the internet. This is fun! All played by known actors (the head of security in 24h chrono) or less known ...
So in summary, I liked the book and loved the concept. To be continued with volumes 2 and 3.
