Sunflower Sisters (Lilac Girls Series Book 3) by Martha Hall Kelly

Set during the tumultuous American Civil War, this gripping historical novel weaves together the lives of three very different women whose fates collide. Georgeanna Woolsey volunteers as a Union nurse, Jemma is an enslaved girl fighting for her freedom, and Anne May is a plantation mistress fiercely loyal to the Confederacy. Through courage, resilience, and sacrifice, these remarkable women navigate the profound divisions of a fractured nation.
