Some men are hard to kill. Colt Ostergaard is something else entirely.

On the frontier world of Fenris — where forty-year winters give way to savage springs, where ranchers ride six-legged yimas across golden plains, and where the scars of a brutal independence war haven’t finished healing, one man drifts from trouble to trouble, justice to justice, and never seems to slow down.

Colt Ostergaard is a former soldier, court-martialed for an act of mercy that saved hundreds of lives and cost him everything else. He carries a hand-crafted Diamond Firearms Shark Elite, a pocket watch with his grandfather’s name inside, and a reputation that arrives in town a full day before he does. He doesn’t look for fights. Fights find him. And the men who start them rarely finish standing.

Across the high plains of Fenris, Colt will face Feral raiders, rogue Alphan soldiers, corrupt lawmen, a disgraced general raising a private army in an underground fortress, and a powerful foundation that has been hunting him for reasons he doesn’t fully understand — and won’t stop, no matter what it costs them.

Riding alongside him is Shelby Yodersen, who introduced herself at fifteen with a pink shotgun and has been saving his life-and complicating it-ever since.

Collecting all of Rick Cutler’s stories from the complete six-volume Space Cowboys anthology series by Raconteur Press, plus new chapters written exclusively for this novel, Colt Ostergaard: A Man With a Gun is the definitive arc of one of independent science fiction’s most original characters.

Science fiction written like a Western. A frontier that doesn’t forgive mistakes. A story for anyone who believes the best science fiction has always been a morality play with better guns.
