The Echo Maker

On a winter night on a remote Nebraska road, 27-year-old Mark Schluter flips his truck in a near-fatal accident. His older sister Karin, his only near kin, returns reluctantly to their hometown to nurse Mark back from a traumatic head injury. But when he emerges from a protracted coma, Mark believes that this woman–who looks, acts, and sounds just like his sister–is really an identical impostor. Shattered by her brother's refusal to recognize her, Karin contacts the cognitive neurologist Gerald Weber, famous for his case histories describing the infinitely bizarre worlds of brain disorder.
