Stampedes, wild animals, and renegade Comanches make a cattle drive dangerous for any man. The risks multiply when Charlotte Grimes goes up the trail disguised as Charlie, a fourteen year-old boy. She promised her dying father she'd save their ranch after her brother, Tobias, mismanages their money. To keep her vow, she rides the trail with the brother she can't trust.
David Shepherd needs one more successful drive to finish buying the ranch he's prayed for. He partners with Tobias to travel safely through Indian Territory. David detests the hateful way Tobias treats his younger brother, Charlie. He could easily love the boy like the brother he's always wanted. But what does he do when he discovers Charlie's secret? What kind of woman would do what she's done?
The trail takes an unexpected twist when Charlotte falls in love with David. She's afraid to tell him of her deception. Such a God-fearing, honest gentleman is bound to despise the kind of woman who dares to wear a man's trousers and venture on a cattle drive. Since her father left her half the ranch, she intends to continue working the land like any other man after she returns to Texas. David would never accept her as she is.
Choosing between keeping her promise to her father or being with the man she loves may put Charlotte's heart in more danger than any of the hazards on the trail can.
