The author should be understood as the person on whose behalf we will write a review. For example, it could be a company if your customer works in the B2B sector, or a person to whom your customer has built a house. You need to ask both parties for the most detailed information about the cooperation. Let the customer tell what services he provided.
A response is a text in which they evaluate what they have read, heard, seen, and express their attitude to it. The purpose of the review is to describe your feelings and thoughts that came from getting to know the author and his work, as well as to recommend the book or work to other readers. the review can be written in the form of reasoning, then it usually contains the thesis (the reader’s opinion about the book), evidence of the validity of this opinion; conclusion (general assessment of the book); recommendations (who to read this book).
