In the harsh mountains of Arizona, Ronald Kerry arrives at Lonsdale Castle carrying a reputation that follows him everywhere: that of an assassin.

Hunted by suspicion and rejected by the people around him, Ronny accepts a strange position as manager of the isolated Lonsdale estate. But the ranch is not an ordinary cattle farm. Ancient rivalries, stolen herds, outlaw gangs and a brutal family conflict are waiting for him beyond the mountains.

At the center of the danger stands the mysterious Bolibar, a ruthless cattle thief whose feud with the Lonsdales has turned the mountains into a battlefield.

Ronny soon discovers that survival will require more than courage and a fast hand. He must face deadly ambushes, impossible escapes, treacherous mountain passes and a rival who may be more dangerous than any outlaw.

Yet the greatest struggle is not fought against Bolibar.

It is fought between two men who love the same woman.

Set against the spectacular wilderness of the American West, The Thief's Pass combines adventure, romance, violence, humor and frontier legend in a fast-moving tale where loyalty is tested, reputations are shattered, and old rivalries can only end in a final confrontation.
