Before We Were Yours, by Lisa Wingate (2017)

Before We Were Yours is a fictionalized account of children who were held in the Tennessee Children's Home Society. It is readable and engaging, and alternating chapters are told by an elderly woman who was abducted at 12 (Rill Foss / May Crandall) and a 30 year old politician-in-waiting (Avery Stafford) whose family has kept their ties to the Society a secret.

The Children's Home Society was operated during the first half of the twentieth century by Georgia Tann (1891-19150). She and her staff essentially kidnapped and sold children to upper class families, relying on the argument that they were finding more suitable homes and "helping" all involved. 

Tann's work was supported and/or endorsed by E.H. "Boss" Crump and other influential Memphis politicians. Crump was the mayor of Memphis from 1910 to 1915, and he effectively controlled the city for a couple of decades thereafter.
