Book excerpt: They were an inseparable tribe of childhood friends whose world was torn apart by the First World War. Some were lost in battle, and those who survived have had their lives unimaginably upended, scattered to Ceylon and India, France and Germany, and, inevitably, back to Britain. Now, at the dawn of the 1920s, all are trying to pick up the pieces. At the center of Louis de Bernières’s riveting novel are Daniel, an RAF flying ace, and Rosie, a wartime nurse. As their marriage is slowly revealed to be built on lies, Daniel finds solace—and, sometimes, family—with other women, and Rosie draws her religion around herself like a carapace. Here too are Rosie’s sisters—a bohemian, a minister’s wife, and a spinster, each seeking purpose and happiness in her own unconventional way; and Daniel’s military brother, unable to find his footing in a peaceful world. Told in brief, dramatic chapters, So Much Life Left Over follows the stories of these old friends over the decades as their paths re-cross or their ties fray, as they test loyalties and love, face survivor’s grief and guilt, and adjust to a new world.
