The daughter of an Irish homesteader father and a Blackfeet Indian mother, Amanda is eager to see the world. Her plans become entangled when she stumbles across evidence that links a corrupt local lawman to a vicious crime. A rock slide on the train tracks strands the travelers, leaves a U.S. Army payroll vulnerable to outlaws, and places Amanda?s life in danger. U.S. Marshal Thomas Benton is working with the army and steps in to escort Amanda to safety as events escalate toward conflict. The most difficult struggle looms in her heart as Amanda follows Thomas through all the dangers of the American West in the year of 1870.
