Work on the Santa Fe Trail, and on a Mississippi River boat give him a start, but the years of Civil War leave him broke and footloose in South Texas. There he discovers more cattle running loose than he ever knew existed. Teaming up with two ex-Federal soldiers, he sets out to gather his wealth, one head at a time. While gathering and driving Longhorns, Mac and his friends meet an interesting collection of characters, including Margo. Mac and Margo and the crew learn about Longhorns, and life, from hard experience before they eventually head west. Outlaws and harrowing river crossings are just two of the challenges they face along their way.

    He hunted outlaws like some men hunted wolves or mountain lions. The bounties he collected were simply payments rendered to a workman, and he was a man good at his work. Under Eli’s flint-hard exterior, that was merciless to outlaws, ran a wide streak of kindness that showed itself the day he picked up a starving orphan in Dodge City and took him along. He soon learned that the twelve-year-old Rob Slater harbored a common intent with him – to run down the elusive Parson gang. He for the $10,000 reward, and Rob, because Jude Parson had murdered his folks. Rob asked Eli to teach him the trade so one day he could look Jude Parson in the eye and square things with the killer. Under Eli’s tutorage the two came to turn the outlaw world on its ear until the day Eli honored his brother’s dying request and took his young daughter into his care touching off a series of unexpected changes that would forever mold their futures.

    The only friend he can rely on is a blue mustang with the cunning and heart of a fighter.
