Last Chance Cowboy by Cathy McDavid

The Powell Ranch is not the expansive spread it used to be. With a good part of its land sold off to developers, Gabe Powell is struggling to save his disappearing way of life. He has a legacy to leave his daughter, and starting a stud farm would give him financial stability. But first he must capture the wild horse he's spotted in nearby Mustang Valley.

Sage Navarre is in Arizona on an urgent domestic matter that will secure her young child's future. And as a government field agent, she's been ordered to help Gabe track down an escaped mustang while she's here. Working with the cowboy is an incredible experience–and Sage finds herself wildly attracted to him.

But what will Gabe say when she dashes his dreams for his ranch? Because he's not the only one who wants that mustang.
