Staked out on an anthill and left to die in the Mexico desert isn’t a great way to start the day.

Broke again, Ace takes a job riding shotgun on a wagon delivering supplies to Dace Jackson, the richest cattle baron in the Arizona Territory. It’s just a job until Ace learns that the ruthless Jackson is trying to steal an entire town. Then it’s personal. Especially once he meets Annie, a beautiful young woman with green eyes a man could drown in. But what can one man do against an army of hired gunmen? It won’t be enough to be fast with a gun. He’ll need smarts too. And a whole lot of luck. The Lone Wolf Howls series can be read in any order.
