I read this third book in one sitting, I could not let go of it. I, who rarely read that day, I abandoned my video games to finish this book says it all !! I love that the character is a boy of my age, who embarks on a lot of adventures and different worlds: here it happens in a prison for young offenders that must infiltrate. The next book is going in a suburb and he must infiltrate a gang. This leads me to the world I do not know, it's exciting. Guillaume (Fade cool books)
