I found this book by accident on Overdrive.
Set in rural Kentucky during segregation, Olivia tells her story of growing up poor with a mentally unstable Mama, raising her grandson, and uncovering secrets her Pap tried to hide from her.
I enjoyed this. It felt like talking to my grandma. Older people in the South have their own language, and Wall captured that with lines like "While I love the boy more than life, Ida's a hole in another sock."
