Cherokee Warriors: The Lover by Genell Dellin

Desperate to save her small farm, Susanna Copeland decides to drive a herd of cattle to Kansas—but no crew will work for a woman. Looking for a man who'll pretend he's her husband, she bails Eagle Jack Sixkiller out of jail...and gets more than she bargained for. Jack enjoys beautiful women, and he especially enjoys teasing his "wife," kissing her in front of the men, inventing new verses of "Oh, Susanna", and inisting they share a tent. After all, to protect their charade—and her—everyone must believe they're married. And Susanna finds she likes it all much too much. But, happily widowed, she's decided no man will ever control her life again. Yet as they face stampedes, hailstorms, and theives together, they begin sharing a bedroll—and soon, their hearts.
