The approach to introduce a new way of thinking by telling a story is fresh and diversifed way of applied theory. In this book the author tells a story about how you could change your way of communication in order to ask the right questions.
The basic idea is very simple but smart and could be helpful actually. But the story surrounding this approach is very lengthy and doesn't adding any value, beside a practial example.
In result it is a nice book for everyone who is open minded for new ideas and who has time (!) For me the second half of the book was much to long and it tend to be annoying.
