In The Sky-Liners, Louis L'Amour introduces Flagan and Galloway Sackett, heading west from Tennessee to seek their fortunes. That's when they came across an old Irish trader who offered them two fine horses if they would agree to escort his granddaughter, Judith, to her father in Colorado. Flagan saw nothing but trouble in the fiery young woman, but they needed the horses. Unfortunately, Flagan was right, for Judith had fallen for James Black Fetchen, a charismatic gunman whose courtship hid the darkest of intentions.

Now Fetchen and his gang are racing the Sackett brothers to Colorado--leaving behind a trail of betrayal, robbery, and murder. Flagan and Galloway can only guess why Judith is so important to Fetchen and what awaits them at her father's ranch. One thing Flagan knows for sure: The tough and spirited woman has won his heart. But can he trust her with his life?
