White Vengeance (White #11)
Susan Edwards

Dakota Territory, 1867 ... The day Ranait O'Brien buried her parents, she vowed to do anything to keep her family together. When Sheriff Tyler tried to place her young siblings in foster homes, Renny swore never to trust him again. No matter how he tries to make it up to her, or how tempting it is to fall into his arms and return his passionate kisses...
Tyler only wanted to help the beautiful and spirited Renny, but his actions turned her against him. Eager for her forgiveness, he offers to accompany her on a quest to find her Sioux brother--and he won't take no for an answer.
Infuriated at Tyler's interference, Renny is more determined than ever to prove she doesn't need anyone's help. But as the journey across the plains draws her closer to her mother's people, and to the one man who accepts her as she is, Renny learns she must be at peace with the past before she can embrace the future.
