Q: I’m a book author and I belong to a group where we agree to post reviews in social media for each other. I’ll review someone else’s book on a book review site or a bookstore site if he or she reviews my book. No money changes hands. Do I need to make a disclosure?
A: It sounds like you have a connection that might materially affect the weight or credibility of your endorsements (that is, your reviews), since bad reviews of each others’ books could jeopardize the arrangement. There doesn’t have to be a monetary payment. The connection could be friendship, family relationships, or strangers who make a deal.
