Why would anyone want to try to combine an old line Amish book with a new-ageish “re-birth” pop psychology and think they could come up with anything that is realistic.
The Pearls are not Amish. They are sort of a very conservative Evangelical type. But when the book was released they originally used a picture of an Amish wagon on the front of the book as a tribute to the training methods of their Amish neighbors.
