Raz was one of those vanguard human beings of indeterminate ethnicity, the magnificent mutts that I hope we are all destined to become given another millennium of intermixing. His skin was a rich pecan color from his dad, who was part African American and part native Hawaiian. His hair, straight and glossy black, and the almond shape of his eyes came from his Japanese grandmother. But their color was the cool blue he'd inherited from his mum, a Swedish windsurfing champion.
