Book excerpt: During World War II, the millions of letters American servicemen exchanged with their wives and sweethearts were a lifeline, a vital way of sustaining morale on both fronts. Intimate and poignant, Miss You offers a rich selection from the correspondence of one such couple, revealing their longings, affection, hopes, and fears and affording a privileged look at how ordinary people lived through the upheavals of the last century's greatest conflict.
