My wife Nancy has written quite a number of fine books. But in my view, her very finest is the book Learning Contentment.
On a related front, Canon Press has recently been making a concerted push to get their list available to all of you in audio. They just recently accomplished that with Learning Contentment, and so I just finished listening to it again. What a great book.
