Climb the Highest Mountain — Rosanne Bittner

Ever since her gaze locked with Lone Eagle's over a crimson campfire, young Abigail Trent knew her fate lay with the virile Cheyenne scout. She had married him, borne him children, and endured all the hardships of the rugged frontier. But even though so many years had passed, each night found the white squaw melded to her Indian mate, burning with the need to prove their passion again and again.

Now new troubles rose to challenge them: Homesteaders poured into the unmapped territory, determined to wrest the land from the forbidden lovers and their "heathen" people. Abbie and Lone Eagle had conquered greater threats than this, surviving bandits and outlaws, fevers and wounds. They would overcome this danger, too, as together they struggled for their own way of life and fiercely embraced their savage destiny.
