Sunny Landers is utterly devoted to her father's dream—a transcontinental railroad that would run from Chicago to the Pacific. Journeying west on a wagon train, she discovers for herself the glories of the unsettled country...and the unsettling half-Cherokee, Colt Travis. He was like the land of his birth: handsome yet wild, imposing, and dangerous. Against an endless horizon, Colt opens her heart to a passion she never dreamed possible. But in a country torn apart by war and progress, can they ever find a way to stay together?
