The Buford Novels are not sequential. The timelines are all over the place and each novel addresses different topics.
You can read book 3 - Blind Man and the Queen - without having read the first two books.
Each novel in the series focuses on a particular aspect of Black Love: personal, social, socio-political, institutional, political and spiritual.
Book 1: My Baby's Father (March 1996)
Book 2: Separate But Equal (October 2010)
Book 3: Blind Man and the Queen (June 2019)
