A Promise to Believe In (Brides of Gallatin County #1) by Tracie Peterson

Gwen, Beth, and Lacy Gallatin fashion a life for themselves in the Montana wilds, operating a roadhouse that is located at the crossroads of two major stage lines. When their father is accidently killed, the oldest sister, Gwen, reasons that she's cursed. After all, death seems to haunt her: her mother, now her father...and she was married for a mere ten days before her husband died from a bout of measles.

As Gwen and her sisters struggle to maintain the inn on their own, an unexpected visitor adds to the mayhem. Hank Bishop claims to be searching for something in the possession of Gwen's late husband. But mayhem of another sort builds in Gwen's heart as she finds a growing attraction to this man. Can she dare to hope that love might again be hers?
