Mary Louisa Roberts won the race of a lifetime—or so she thought. In competition with desperate homesteaders, ruthless land seekers, and a sheriff determined to see her fail, Mary rides out on a horse to strike her claim in the Oklahoma Land Rush of 1893. When she finally thrusts her flag into the dirt, 160 acres becomes her own. But with that claim, she risks more than she could ever imagine. A naïve school teacher and young mother abandoned by her hard-drinking, gold-seeking husband—whom she now believes to be dead—Mary is faced with letting go of a past riddled with loss, hardship, and reminders that a woman isn't capable of surviving on her own.
