Set beneath the vast skies and unforgiving landscapes of Montana, the Frontier Series follows Deputy U.S. Marshal Danny Coogan—a former Afghanistan veteran and Montana Fish and Game officer who keeps finding himself caught between violence, loyalty, and the hard truths buried in rural America.
What begins as one man’s search for a quieter life in the small town of Darwin quickly becomes a relentless fight for survival. Across remote ranches, frozen mountain passes, reservation land, and forgotten ghost towns, Danny is pulled into investigations involving murder, cattle rustling, drug operations, corruption, missing persons, and buried secrets that powerful people would kill to protect.
As threats close in from every direction, Danny must navigate the uneasy line between federal law, local loyalties, and the people he considers family. Each case pushes him deeper into a modern frontier where justice is rarely clean, trust can get you killed, and violence often arrives long before backup.
Blending modern Western grit with nail-biting suspense, the Frontier Series delivers rugged landscapes, complex characters, sharp wilderness humor, and high-stakes action. Fans of Longmire, Joe Pickett, and The Highway will find a world where survival depends on instinct, courage, and knowing who to trust when the frontier turns deadly.
