Brianna McGraw ventures out West to find and rescue her brother from bandits who will sell him illegally to the highest bidder. Separated after they were orphaned a few years ago, Brianna has worked hard as a librarian to save money for the trip. But when she arrives, she realizes she has to somehow come up with a thousand dollars to buy him back.

She then sees a wanted poster with a sufficient reward and decides to become a bounty hunter, accomplishing two good deeds at once—bringing a criminal to justice and saving her brother.

Trey Morgan’s renegade days are long over. He is at home on his ranch, tending to his cattle, when Brianna appears and arrests him. He is more amused than concerned, wondering how she thinks she’s going to drag him 900 miles through the mountains.

To his surprise, Brianna proves over and over again that she is intelligent and strong enough to make the long and grueling trip. While he quietly observes his beautiful captor, his discomfort grows when she begins to win more and more of his respect and admiration.

Soon, the threat his beautiful captor holds over him is not so much in the pistol she wields, but the lasso she has firmly fastened over his heart.
