'm a retired teacher and have purchased three sets for some of my grandchildren. I encourage all adolescents and adults to read the children's books. I'm about to read the "Courageous Heroes" "Logical Fallacies" and "Inspiring Entrepreneurs"
Keep up the good work on trying to save our children from the Marxist - Communist agenda!
