A few minutes after 9 p.m. on Palm Sunday, April 5, a massive funnel cloud flashing a giant fireball and roaring like a runaway train careened into the thriving cotton-mill town of Tupelo, Mississippi, killing more than two hundred people—not counting an unknown number of black citizens, one-third of Tupelo’s population, who were not included in the official casualty figures. When the tornado hits, Dovey, a local laundress, is flung by the terrifying winds into a nearby lake. Bruised and nearly drowned, she makes her way across Tupelo to find her small family her hardworking husband, Virgil; her clever sixteen- year-old granddaughter, Dreama; and Promise, Dreama’s beautiful light-skinned three-month-old son. Slowly navigating the broken streets of Tupelo, Dovey stops at the house of the despised McNabb family. Inside, she discovers that the tornado has spared no one, including Jo, the McNabbs’ dutiful teenage daughter, who has suffered a terrible head wound. When Jo later discovers a baby in the wreckage, she is certain that she’s found her baby brother, Tommy, and vows to protect him. During the harrowing hours and days of the chaos that follows, Jo and Dovey will struggle to navigate a landscape of disaster and to battle both the demons and the history that link and haunt them.
