http://en.wikipedia.org/wiki/Shill A shill, plant or stooge is a person who helps a person or organization without disclosing that he or she has a close relationship with that person or organization. Does that fact that he wrote a book for the same publisher constitute ‘a close relationship’? Me thinks no. :::Shill typically refers to someone who purposely gives onlookers the impression that he or she is an enthusiastic independent customer of a seller (or marketer of ideas) that he or she is secretly working for. The review is detailed. This is not marketing. What’s your problem?

http://en.wikipedia.org/wiki/Book_review A book review is a form of literary criticism in which a book is analyzed based on content, style, and merit.[1] A book review could be a primary source opinion piece, summary review or scholarly review.[2] It is often carried out in periodicals, as school work, or on the internet. And he did just that. He analyzed and recommended it. What do you want?
