The captain of the Gray-horse troop

The Indian Wars are over. The rivers that ran with blood are clear. The plains that rang with war cries and gunshots are silent. But now a new war is about to start. Deadlier, bloodier, and even more cruel.... Captain George Curtis of the U.S. Cavalry has been sent to take over the Indian Agency at Pine Ridge. His job is to make and maintain a fragile peace between cattlemen and the Indians. What Curtis doesn't know is that he has secret enemies in Washington who want him to fail.
