a book on a good action comedy tone

I expected a Matrix 2.0, a theory in which people influence us through internet, something that we do ask questions, but that's not really the purpose of this book.
It has to do with a character No Life, who spend too much time in front of his PC and finds himself against his will in a turbulent history alongside a killer. What is amusing throughout this book is that this guy thinks he is in a video game and that despite the magnitude of what will happen, it will take everything to cool. Well of course the story revolves around the Internet, people who control everything etc .. but that's not what interested me most in this book. I will remember the humorous side of the story.
The book reads very well and very quickly thanks to in another chapter 2 or 3 pages every time.
I think I'll read the next book by this author.
