It's the scorching summer of 1878, and a bitter range war is threatening to blow Montana Territory sky-high. On one side there's the all-powerful Stock Grower's Association and its 50-strong army of hired guns. On the other, there's just a handful of families who'll fight to the death to keep the land they've settled on. Trouble is, the Association is slowly but surely winning the struggle. When they're not stealing the settlers' stock, they're burning them out and shooting them down, and there's not one damn thing the victims can do about it.
Until, that is, Ash Colter happens along. And when he buys into it, the odds change overnight. Colter really is the fastest gunfighter in the west, and as the Association soon learns to its cost, you don't mess with the man they call the Gunsmoke Legend.
