Gown of Spanish Lace (Women of the West Book #11) 

Ariana loves her life as a schoolteacher in a little frontier town. But one evening after classes are done and she prepares to hurry home, her life changes in an instant when a band of rough outlaws abduct her and take her far away from all she has ever known. Trapped in a small shack, Ariana prays and waits, her emotions swinging between terror and boredom as days stretch into weeks. Still, the outlaws refuse to tell her why they’ve taken her or what they plan to do.Then the boss’s son appears in the doorway of her cabin. He seems different from the others, but can she trust him? Will she ever again see her mother and father, the couple who lovingly adopted her and raised her as their own? Will she ever wear the beautiful wedding dress so carefully saved for her–her one remaining link to her birth parents?
