One of the most horrific episodes in American history occurred on December 29, 1890. The U.S. Cavalry surrounded an encampment of Lakota on the Pine Ridge Reservation in South Dakota and massacred some 300 people. The details of the carnage of the Wounded Knee Massacre are almost unbearable. As Black Elk, the Lakota medicine man who witnessed the massacre, put it, “Something else died there in the bloody mud, and was buried in the blizzard. A people’s dream died." This tragedy is the bleak backdrop for Jonis Agee's new novel, "The Bones of Paradise." Set 10 years after the Wounded Knee Massacre, all the characters in her novel - from white cattle ranchers to the Lakota - are wrestling with the ghosts of the massacre. Agee tells Steve Paulson about the origins of her novel.
