Tears Like Rain (Trails West Trilogy #1)
Connie Mason

As untamed as the prairie, as free as the wind, she hated what white men were doing to the Cheyenne. But spirited Tears Like Rain risked her life to save a cavalry officer and made him her slave.
The Soldier …
Although the Indians had beaten and stabbed Zach Mercer to the brink of death, the real torture didn’t begin until Tears Like Rain rescued him. Never had Mercer ached so desperately for a woman who scorned him. Zach longed to make his beautiful virgin captor desire him as fiercely as she now despised him, but he wouldn’t succeed until they both learned a different lesson: that only the bonds of love are unbreakable.
