"Terry Johnston is an authentic American treasure."-Loren D. Estleman, author of Edsel It was a day that shocked a nation. June 25, 1876. The day General George Armstrong Custer fell at Little Big Horn. Now the U.S. Army is on the march. Vowing revenge, its commanders have declared total war on the Cheyenne and Sioux. Every able-bodied man must answer the call of the cavalry trumpet . . . men such as frontiersman Buffalo Bill Cody and scout Seamus Donegan. From the Black Hills to Slim Buttes, from Yellowstone to Warbonnet Creek, some would succumb to ambush, some to starvation, others to disease and even madness. Under the blood-red sun of that terrible summer, Seamus Donegan prays only to survive . . . to return to his wife, Samantha, and witness the birth of their first child.
