A review is a form of feedback to tell an author what is thought of their work, and offer opinions of the story and the skill of the writing. These are usually written and can be found in newspapers, magazines, and on booksleeves. For an example of what happens when an "author" does not learn how to deal with reviews, take a look at BigAl's review of "The Greek Seaman" by Jacqueline Howett. Read the review. Then read the comments. Laugh. Weep. Learn.
