Two former female spies, bound together by their past, risk everything to hunt down an infamous Nazi doctor in the aftermath of World War II in this pulse-pounding novel inspired by true events from the New York Times bestselling author of LILAC GIRLS.

Martha Hall Kelly’s LILAC GIRLS introduced readers to Caroline Ferriday. Now, in SUNFLOWER SISTERS, Kelly tells the story of Ferriday’s ancestor Georgeanna Woolsey, a Union nurse during the Civil War whose calling leads her to cross paths with Jemma, a young enslaved girl who is sold off and conscripted into the army, and Anne-May Wilson, a Southern plantation mistress whose husband enlists.

From Martha Hall Kelly, the New York Times bestselling author of LILAC GIRLS, comes LOST ROSES, a sweeping novel inspired by true events that follows three equally indomitable women from St. Petersburg to Paris under the shadow of World War I.

For readers of THE NIGHTINGALE and SARAH’S KEY, inspired by the life of a real World War II heroine, this remarkable debut novel reveals the power of unsung women to change history in their quest for love, freedom, and second chances.
