Set in the late 1800s, this is a charming YA novel about Jo Kuan, lady’s maid by day and “Dear Sweetie” by night. She writes an advice column for the gentile ladies of Atlanta, doing her best to help fix society’s ills. When she pushes back on race and gender roles, angry readers try to find out who Miss Sweetie is. Then Jo receives an anonymous letter that could lead to the identity of her birth parents, and she has a lot of decisions to make.
