Nicolas von Bingen and Alex von Hemmerle, titled members of the German aristocracy, have been best friends since childhood. Both widowers, they are raising their children, Nick's two lively boys and Alex's adored teenage daughter, in peace and luxury on the vast Bavarian estates that have belonged to their families for generations. While Nick indulges in more glamorous pursuits, Alex devotes himself to breeding the renowned white Lipizzaner horses that enthrall audiences throughout Europe with their ability to dance and spin on command, majestic creatures whose bloodlines are rare and priceless. But it is Nicolas's bloodline that changes everything, when his father receives a warning from a high-ranking contact inside the Wehrmacht. A secret from the past has left the family vulnerable to the rising tide of Nazism: Nick's mother, whom he never knew, was of Jewish descent.
