I am a brand new subscriber to the Bookmarks web site , and I have been trying to find the name of a book that was read on National Public Radio in the summer of 1993.The book is non-fiction and is about parents who are homesteaders in the American nort west in the middle 1970's. They have four sons who are home schooled and all end up attending Harvard and several become doctors of medicine. Sound familiar ? Thanks in advance for any help ! Howard /Columbus,OH.
