Query: F word prevails!

We bought the audio book because it seemed silly. No warning on the package. First story is f-word littered. Not a family product. Harper Audio, I have learned my lesson. I will not buy your products since I can't count on the label being truthful, and I will also research other audio books before I suject my family to such garbage.
