Marriage, A History. By Stephanie Coontz is an extensive look at the history of marriage and how it has evolved over the course of human history. That might not sound exciting to you, but it should be. The book is incredible and shows how marriage has gone from a logical and emotionless decision to one solely based on love and emotion. You will be entertained and enlightened and honestly you should have already bought this book yesterday. Full disclosure if you click the link and buy the book or anything else I make money. Like, making it rain pennies, and maybe even a few nickels kind of money.
