I start right away with the best thing. The book is written with very great consideration and insight. The content is fluent to read which makes it easy to adapt and learn. The book is separated to logical chapters which build the subject on top of the previously learned things and same logic is used when carrying the discussion inside a chapter. Therefore there should be no problem in understanding what is discussed.
After reading a couple of paragraphs from first chapters it is clear that the book has something major to say about the subject and the author has very strong insight to the things he discusses. Every good book has always a good plot despite the subject and this book makes no exception. The code examples are very practical and are very accurately targeted to the every particular context they are represented in.
Generally the book is top quality content and it is hard to raise anything else that is top over the others. The book is absolutely in my Top 5 list so far.
