I have not read the book.....but as a brother in-law....I can comment on ken holly's characture. Ken is a man of his word....what he says he will do....he does. he has an internal compass and core values that sets his actions and reactions. His calm and balance is impressive. Never has ever lost his cool regardless of the situation. He demonstrated all the traditional duties to GOD, Family, work, and friends.
I have not talked to Ken in a number of years but.....I know he is well.
