The first book that I read, written by any medical professional about any controversy. At the time that I read it I needed to look up a lot of terms and procedures but it was worth it. Even though it was a difficult read (two volumes) it was worth it because it brought questions to mind that I had never considered. 4 stars only because it was difficult to get thru. The book is no longer available and the author (Dr. Eva Snead) not available for comment.
