Kelly, Martha :Sunflower Sisters (Lilac Girls #3)

Martha Hall Kelly 

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.
