Trails West Trilogy Series by Connie Mason

As untamed as the prairie, as free as the wind, she hates what white men are doing to the Cheyenne. But spirited Tears Like Rain risks her life to save a cavalry officer and make him her slave. Although the Indians have beaten and stabbed Zach to the brink of death, the real torture doesn't begin until he loses his heart to Tears Like Rain.

Born white but raised by Indians, Wind Rider lived to protect the Indian lands from white settlers. But who would protect him from the exasperating Irish beauty whose soft, sensuous touch seared his soul? Fiery and tempestuous western romance by the author of Tears Like Rain, who was named Romantic Times's Storyteller of the Year.

Everybody knew a proper lady like Sierra didn't go traipsing through untamed lands with a perfect stranger, especially one as devilish as Ramsey Hunter, her unwilling guide and tutor in the ways of love. Sierra believed the rumors that said her long-lost siblings were living in Denver, and she'd put her reputation and heart in peril to find them--as would Ramsey.
