Martha Hall Kelly is the New York Times bestselling author of Lilac Girls and Lost Roses. She lives in Connecticut, where she spends her days filling legal pads with stories and reading World War II books.

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—an extraordinary novel inspired by true events from the New York Times bestselling author of Lilac Girls

American Josie Anderson and Parisian Arlette LaRue are thrilled to be working in the French resistance, stealing so many Nazi secrets that they become known as the Golden Doves, renowned across France and hunted by the Gestapo. Their courage will cost them everything. When they are finally arrested and taken to the Ravensbrück concentration camp, along with their loved ones, a reclusive Nazi doctor does unspeakable things to Josie’s mother, a celebrated Jewish singer who joined her daughter in Paris when the world seemed bright. And Arlette’s son is stolen from her, never to be seen again.

A decade later the Doves fall headlong into a dangerous dual mission: Josie is working for U.S. Army intelligence and accepts an assignment to hunt down the infamous doctor, while a mysterious man tells Arlette he may have found her son. The Golden Doves embark on a quest across Europe and ultimately to French Guiana, discovering a web of terrible secrets, and must put themselves in grave danger to finally secure justice and protect the ones they love.

Martha Hall Kelly has garnered acclaim for her stunning combination of empathy and research into the stories of women throughout history and for exploring the terrors of Ravensbrück. With The Golden Doves, she has crafted an unforgettable story about the fates of Nazi fugitives in the wake of World War II—and the unsung females spies who risked it all to bring them to justice.

Martha Hall Kelly’s million-copy bestseller 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.

“An exquisite tapestry of women determined to defy the molds the world has for them.”—Lisa Wingate, #1 New York Times bestselling author of Before We Were Yours

Georgeanna “Georgey” Woolsey isn’t meant for the world of lavish parties and the demure attitudes of women of her stature. So when war ignites the nation, Georgey follows her passion for nursing during a time when doctors considered women on the battlefront a bother. 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 Plantation 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.
