Many of your books are collaborations. What is the difference between writing collaboration and ghostwriting?
For the first dozen years I wrote for others, it was truly ghostwriting. That means readers didn't know who wrote the book. For example, I wrote books for celebrities such as Joyce Meyer; Franklin Graham; and Truett Cathy, founder of Chick-fil-A.
Collaboration has two meanings. First, you get credit on the book—shown by with Cecil Murphey, as I did with Gifted Hands and 90 Minutes in Heaven.
Second, if you write with someone but much of the writing is yours, you're also a collaborator and you have the word and before your name. (I did three additional books with Don Piper, all with and.)
