Query: A word of warning.....

Based on an article in the Wall Street Journal and the previous reviews, I bought this book, and Missing Links by Dan Jenkins, for my father-in-law, an avid golfer and reader. He was so disgusted by the language in both books (the c-word, f-word etc. "on every page") that he returned them.
