The Man Who Tasted Shapes by Richard E. Cytowic
"The ten people in a million who are synesthetes are born into a world where one sensation (such as sound) conjures up one or more others (such as taste or sound). Although scientists have known about synesthesia for two hundred years, until now the condition has remained a mystery. Extensive experiments with more than forty synesthetes led Richard Cytowic to an explanation of synesthesia-and to a new conception of the organization of the mind, one that emphasized the primacy of emotion over reason." from the back cover
