After the death of her abusive husband, Sarah Gregg is free to join her family along with thousands of others in the nation's westward march for gold. But in the middle of the hard journey, Sarah's younger sister, Florrie, disappears. Devastated by the family's failed attempts to find her missing sister, Sarah now wants only to settle into a quiet, uneventful life when she reaches California . . .

In the roaring mining town of Gold Creek his attentive persistence points Sarah toward new vistas. Then unexpected news of Florrie arrives -- and it's worse than anyone expected. But driven by a new hopefulness, Sarah seeks help from Jack, despite his troubled past. The two have traveled a rough road together, and only their hearts can tell them where they are headed . . .
