The cover of this book gave me the impression that the contents of the book would be presented in an overly academic way: that is far from the truth. All that you will ever need to know about Assembly language is covered in the most skilful of ways. At no time have I felt intimated by the author's wisdom or expertise: a sign of a master, in my opinion. It's strange really, because if someone had shown me the inside of this book before I bought it then I am absolutely certain that I would have dismissed it without any justification at all. I am delighted that I bought this book.
