Inspired by the life of a real World War II heroine, this powerful debut novel reveals an incredible story of love, redemption, and terrible secrets that were hidden for decades. On the eve of a fateful war, New York socialite Caroline Ferriday has her hands full with her post at the French consulate and a new love on the horizon. But Caroline’s world is forever changed when Hitler’s army invades Poland in September 1939—and then sets its sights on France. An ocean away from Caroline, Kasia Kuzmerick, a Polish teenager, senses her carefree youth disappearing as she sinks deeper into her role as courier for the underground resistance movement. In a tense atmosphere of watchful eyes and suspect neighbors, one false move can have dire consequences. For ambitious young German doctor, Herta Oberheuser, an ad for a government medical position seems her ticket out of a desolate life. But, once hired, she finds herself trapped in a male-dominated realm of Nazi secrets and power. The lives of these three women are set on a collision course when the unthinkable happens and Kasia is sent to Ravensbrück, the notorious female-only Nazi concentration camp. The tragedy and triumph of their stories cross continents—from New York to Paris, and Germany to Poland—capturing the indomitable pull of compassion to bring justice to those whom history has forgotten. In Lilac Girls, Martha Hall Kelly has crafted a remarkable novel of unsung women and their quest for love, happiness, and second chances. It is a story that will keep readers bonded with the characters, searching for the truth, until the final pages.

The runaway bestseller Lilac Girls introduced the real-life heroine Caroline Ferriday. This sweeping new novel, set a generation earlier and also inspired by true events, features Caroline's mother, Eliza, and follows three equally indomitable women from St. Petersburg to Paris under the shadow of World War I. It is 1914 and the world has been on the brink of war so many times, many New Yorkers treat the subject with only passing interest. Eliza Ferriday is thrilled to be traveling to St. Petersburg with Sofya Streshnayva, a cousin of the Romanov's. The two met years ago one summer in Paris and became close confidantes. Now Eliza embarks on the trip of a lifetime, home with Sofya to see the splendors of Russia. But when Austria declares war on Serbia and Russia's Imperial dynasty begins to fall, Eliza escapes back to America, while Sofya and her family flee to their country estate. In need of domestic help, they hire the local fortuneteller's daughter, Varinka, unknowingly bringing intense danger into their household. On the other side of the Atlantic, Eliza is doing her part to help the White Russian families find safety as they escape the revolution. But when Sofya's letters suddenly stop coming she fears the worst for her best friend. From the turbulent streets of St. Petersburg to the avenues of Paris and the society of fallen Russian emigre's who live there, the lives of Eliza, Sofya, and Varinka will intersect in profound ways, taking readers on a breathtaking ride through a momentous time in history.

Lilac Girls introduced readers to Caroline Ferriday, an American philanthropist who helped young girls released from Ravensbruck concentration camp. Now, in Sunflower Sisters, Kelly tells the story of her ancestor Georgeanna Woolsey, a Union nurse who joins the war effort during the Civil War, and how her calling leads her to cross paths with Jemma, a young enslaved girl who is sold off and conscripted into the army, and Ann-May Wilson, a southern plantation mistress whose husband enlists. Georgeanne "Georgey" Woolsey isn't meant for the world of lavish parties and demure attitudes of women of her stature. So when the war ignites the nation, Georgey follows her passion for nursing during a time when doctors considered women a bother on the battlefront. In proving them wrong, she and her sister Eliza venture from New York to Washington, D.C., to Gettysburg and witness the unparalleled horrors of slavery as they become involved in the war effort. In the South, Jemma is enslaved on the Peeler Plantation in Maryland, where she lives with her mother and father. Her sister, Patience, is enslaved on the plantation next door and both live in fear of LeBaron, an abusive overseer who tracks their every move. When Jemma is sold by the cruel plantation mistress Anne-May at the same time the Union army comes through, she sees a chance to finally escape—but only by abandoning the family she loves. Anne-May is left behind to run Peeler Planation when her husband joins the Union Army and her cherished brother enlists with the Confederates. In charge of the household, she uses the opportunity to follow her own ambitions and is drawn into a secret Southern network of spies, finally exposing herself to the fate she deserves. Inspired by true accounts, Sunflower Sisters provides a vivid, detailed look at the Civil War experience, from the barbaric and inhumane plantations, to a war-torn New York City to the horrors of the battlefield. It's a sweeping story of women caught in a country on the brink of collapse, in a society grappling with nationalism and unthinkable racial cruelty, a story still so relevant today.
