I recommend N by Adrienne Pender. It is the story of the historic feud between Charles Gilpin, the first African-American to appear on Broadway, and Eugene O'Neill over the use of the N-word in Emperor Jones. The role gave Gilpin his first big role and also destroyed his career. Also, She'll Find Her Way Home by Valetta Anderson, a family drama in which skin color threatens a budding young romance. It's based on the African-American founders of Mound Bayou, Mississippi right after the Civil War.
This is a historical and dramatic representation of the African-American experience.
