In 1866 Catriona O'Toole arrives in the town of Franklin, Tennessee, searching for her younger brother, Ryan, who, according to his last letter, was headed for Franklin only days before the catastrophic Battle of Franklin. Ryan's last note contained a stack of cash -- enough money to bring his entire family across the ocean from Ireland. But after disease and illness tear through County Antrim and the O'Toole family, only Catriona and her seven-year old sister Nora are left to make the journey.
