In Cowboys Don't Cry, Shane and dad finally settled in to a new life on a ranch in Deer Valley, Alberta. They'd been through some rough times after Shane's mother died in a car accident and his father was drinking too much. But all that was behind them and they were getting along fine together. Or so Shane thought.

Now, in Cowboys Don't Quit, his dad is a day late delivering some bulls to a ranch in Bonzeman, Montana, and Shane is a little worried. Then it's two days. When he gets back from his last day of school and his dad's still not back, Shane decides that he just can't wait around. He's going to Montana to find him.

But crossing an international border and driving hundreds of miles isn't easy when your fifteen, with no driver's license and little money, in a bald-tried old truck. With everything against him—including both sides of the law—Shane is determined to find his dad, before it's too late.
