The reviews for the book are generally four or five stars, with the exception of a couple low ratings. Many people thought the book was very informative and insightful to information they wouldn't have known otherwise about NSA. One of the reviews I had read on Amazon read, "This is a book by a true expert who has spearheaded some of the most powerful investigations into internet spying. If you want some depth and perspective on the NSA scandal, look no further."
Another review read, "Gripping and absolutely terrifying". If you'd like to read any more of the reviews you can see them here at two main websites:
