On a winter night on a remote road in Nebraska, twenty-seven-year-old Mark Schluter's truck turns over in a near fatal accident. His older sister, Karin, his only close relative, 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 recognise her, Karin contacts the cognitive neurologist Gerald Weber, famous for his case studies describing the infinitely bizarre worlds of brain disorder. Weber recognises Mark as a very unusual case of Capgras syndrome and is keen to investigate. But what he discovers in Mark begins to undermine even his own sense of self.

Meanwhile, Mark, armed only with a note left by an anonymous witness, attempts to learn what happened on the night of his accident. The truth of that evening will change the lives of all three beyond recognition.

Set against the spectacular spring migrations of American Sandhill cranes, The Echo Maker is a profound and riveting novel that explores how memory, instinct and relationships make us who we are.
