When Jim Crothers found a box of dusty letters in his Maryland attic, he decided to fulfill a promise he made to his young wife while he was in Vietnam in 1970: He would write a book "about the war nobody knows." These letters hold all the intimate thoughts, dreams, emotions, and philosophy two people shared during a turbulent era in American history. They show how the constant emotional pressure of wartime life affects real people. But, quite simply, these are love letters.
