Distant Heart by Tracey Bateman

Toni Rodden has escaped a life of prostitution and vows she'll never let a man control her again. After months on the wagon train, she's finally earned her place, albeit grudgingly from some, and has found a surrogate family in Fannie Caldwell and her two siblings. For the first time she can taste freedom and the possibilities of a new life. But as Fannie prepares to marry wagon master Blake Tanner, Toni realizes how alone she is and questions whether she'll ever find acceptance, or true love.

Despite Toni's conviction that no man will be able to see beyond her marred past, Sam Two-Feathers, the half-Indian wagon scout and acting preacher for the train, seems to know of a love that forgives sins and values much more than outward appearances. Will Sam have the confidence to declare his love? Will Toni be able to trust in a love that can forgive even the darkest past?
