These Violent Times — C. Courtney Joyner

Outlaws left him with one arm, which he replaced with a specially rigged .12 gauge shotgun. Now Dr. John Bishop has the ultimate cure for evil -- one barrel at a time.

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 protégé, a doctor driven insane by the war, and now hell-bent on spreading pestilence across the land “to witness the cleansing of the West.”

When the psychopath frames Shotgun for the plague-murders, he's forced into a bloody chase, with posses of lawmen, bounty hunters, and a Cheyenne war party on his trail. Dr. John Bishop has only one choice to stop the plague, and clear his name: load up -- and start shooting.
