This is not "investigative reporting." The book is filled with nonsense. The author did not do any basic research into the teachings or traditions of the Holy Catholic Church. Her title is even wrong, all religious women are NOT nuns.We need to thank most of these Sisters who gave their life to Christ. Mercy Sisters founded the first hospital in Chicago. Catholic Sisters came from Europe and immediately went to the Civil War battlefields nursing soldiers from the north and south. I could go on and on about the schools, hospitals, universities founded by these great women.
