Query: The Next Fifty Years

I thought I had ordered the book but it seems the CD was ordered instead. Fortunately the author was kind enough to refund my money but I was very disappointed. After researching what had been the communication problem, the person who was circulating the CD as part of her lecture series was advertising the CD under the book title then stating she was replacing the book with the CD. I personally feel that is an inappropriate way to advertise her product and it should be done separately. I may reorder the book at a later date obviously through a different Amazon distributor.
