The intertwining story of three generations of German immigrants to the Midwest - their clashes with slaveholders, the Dakota uprising and its aftermath - is seen through the eyes of young Asa Senger, named for an uncle killed by an Indian friend. It is the unexpected appearance of Asa's aunt Hazel, institutionalized since shortly after the mass hangings of thirty-eight Dakota warriors in Mankato in 1862, that reveals to him that the past is as close as his own heartbeat.
