A nostalgic cowboy-romance in non-fiction form. This is the memoir of a supreme court justice, not about her life, but about her birthplace and her father. Think if Arya Stark wrote a book about Winterfell, but Americanized completely.

Sandra Day O'Connor and her brother write a book that spends few words on politics, however history of American law is in there regardless. At times not so subtle, this book chronicles the lives of those who lived on The Lazy B ranch, and the changing world distantly around them. If you look you can see America evolve in the background, legally, infrastructurally, and ecologically. 

Politics are downplayed to a minimal. Nothing partisan or truly controversial. It is simply inter-mountain ranching of the twentieth century laid bare for a reader to observe.
