'Sacks is rightly renowned for his empathy . . . anyone with a taste for the exotic will find this beautifully written book highly engaging' Sunday Times Always fascinated by islands, Oliver Sacks is drawn to the Pacific by reports of the tiny atoll of Pingelap, with its isolated community of islanders born totally colour-blind; and to Guam, where he investigates a puzzling paralysis endemic there for a century. Along the way, he re-encounters the beautiful, primitive island cycad trees - and these become the starting point for a meditation on time and evolution, disease and adaptation, and islands both real and metaphorical in The Island of the Colour-Blind.
