Query: Audio CD

This review is about the Audio CD version.The Audio CD book is comprised of four CDs. It's unabridged. I'm happy with the quality of production, and the narration is clear and well done. The case is not plastic, but a paper sleeve type case. Since The Richest Man in Babylon is a story, it's well suited for the audio format and is easy to listen to, and understand. It costs less than most paperbacks (currently $10.97), which is a very good price for an audio books in CD format. If you are thinking about the Audio CD version, you can't go wrong getting it. Recommended.With 500+ five-star reviews, it's superfluous to add anything more about the book itself. So suffice it to say that it's a well done work of fiction that gets the message and teaching across very well. A five-star work indeed.
