Told from the alternating perspectives of two women, Before We Were Yours tells the story of Rill Foss, the oldest of five children who were kidnapped from their family in 1939, and Avery Stafford, a successful lawyer and daughter of a senator. As the novel unfolds, Avery uncovers the links between Rill's story and her own family. Inspired by true events, Lisa Wingate's novel sheds light on the scandals of an adoption center and their exploitation of thousands of children.
