When a socialite from the nation's capital embarks on a journey to the Wild West, her life is changed forever. A setting populated by hundreds of laborers, outlaws, and Indians is hardly the place for a wealthy general's daughter. But Josephine Cain is determined to visit her father, who supervises the day-to-day work involved in the grandest ambition of post-Civil War America: the building of the Transcontinental Railroad. Life with the railroad is far from the proper life Josephine is used to, and she faces deadly gunfights, harsh weather, and vigilante uprisings. She is torn between the West and the East; between her privileged upbringing and the challenges of a new frontier; between the pull of the suitable beau her parents approve of and an attraction to a rough but charming Irish railroad worker. But if Josephine is willing, she just might find a new life, a unique purpose... and true love.
