A great field, but the book is far too sporadic. It attempts to cover so many topics that it inundates the reader. Some chapters are well-written and clear, and some are simply a hodgepodge of examples with no connections to the text. Some of the notation in the book is also quite cumbersome. One thing that was great is the use of mind-maps at the end of the chapter to show the topics and sub-topics covered. If you take a look at these, you'll see how it's easy for this rather short text to take on more than it could handle.
