Teresa

Louise, Blanche, and Eve have survived the Purge, which occured after humans successfully fought back against sentient robots. These three robots, assuming the identities of older southern women, hide in plain sight. 

Until they meet a little girl and her mother, Teresa, both abused by the girl's father. Do the robots remain hidden? Or protect Teresa and her daughter from an abusive tyrant? No matter what they choose, their lives will never be the same again.

For fans of C. Robert Cargill's Day Zero and Sea of Rust.
