Example Input: Review: I have read many authors on the subject of fly fishing. Dave Hughes is a great writer. He puts it in a language a beginner can understand. I am not a beginner but I really like to read his books. I had several of his books and gave them to our new county library. Then I missed them, so I went on amazon and re-bought several of them. Great service! Would do it again. Tight lines.
