How to write a book and make money: Find the hot topic of the day - today's is terrorism, put in your own pet theory or idea about the topic - the author's is how terrorists can use steganography to communicate and finally write a lot of fluff to combine the two. The author has written a poor story, thrown in liberal screenshots and lengthy explanation of how they work.
