Joshua Colter was born of the wild frontier. As a young boy living with his family on the edges of civilization during the French and Indian War, he witnessed firsthand the bloodshed and brutality men were capable of—from the deception and depredations of whites like his own vile father to the merciless vengeance of the native tribes.

Luke Scott just needed to track down some rustlers.The biggest question he had as he rode form his ranch was what kind of idiot rustles cattle in Colorado in December?

It was what he found when seeking emergency shelter that would alter his life forever.

The great state of Texas is a land of opportunity. For outlaws. And horse thieves. And cattle rustlers. Not to mention bank robbers, train robbers, and anything-that-ain’t-nailed-down robbers. The state’s governor, Richard B. Hubbard, is at the end of his rope. He wants to clean up Texas once and for all—and he’s desperate enough to try something crazy: hire a man who can do what the Texas Rangers can’t. A man not tied down by a wife or children. Or rules. Who’s not afraid to go outside the law.
