Shotgun

"Even in the darkest days of the Civil War Dr. John 'Shotgun' Bishop never saw anything like the deadly plague sweeping through the Cheyenne nation. Diseased corpses dumped in the wells of the Great Plains. Women and children bombarded with infected blood during midnight raids. This is the new scourge of germ warfare and it's threatening to wipe out thousands of innocent lives. The culprits are a gang of renegades led by Shotgun's one-time prote̤gé a doctor driven insane by the war and now hell-bent on spreading pestilence across the land 'to witness the cleansing of the West'"--Provided by the publisher.
