Mann Im Dunkel by Paul Auster

An aging, recently operated man lies awake and alone, alternately tending to his pain and to the raw sorrow of a family tragedy, while inventing a vivid alternate America in which political violence erupts into a second civil war; the novel he composes in his head becomes a way to examine guilt, memory, fathers and sons, and the thin line between private grief and public catastrophe, exploring how storytelling can both console and expose moral ambiguity.
