The law has boundaries. The frontier doesn’t. From the frozen backcountry of Montana to the remote reaches of Indian Country, Danny Coogan has built his life around protecting people in places where help is often hours away.
An Afghanistan veteran turned game warden and eventually U.S. Marshal, Danny knows that out here justice is rarely simple. Murder crosses county lines. Criminals disappear into millions of acres of wilderness. Old grudges survive for generations. And the difference between coming home and dying alone can be the person standing beside you.
Across the Frontier Series, Danny faces killers, fugitives, drug runners, domestic terrorists, cattle thieves, kidnappers, and men willing to bury their secrets with the bodies. Along the way, he must navigate the complicated jurisdictions of federal, state, county, and tribal law while protecting the small Montana communities and the people he has come to call home.
Blending hard-edged crime, wilderness adventure, down-home humor, and the rugged character of rural America, the Frontier Series is contemporary Western suspense for readers who believe the most dangerous place in America may be where the pavement ends.
For fans of C. J. Box and Craig Johnson, the Frontier Series delivers murder, mystery, and justice beneath the Big Sky, where backup is a long way off, and trouble is always closer than it looks.
