"Having Our Say: The Delany Sisters First 100 Years" written by Sarah and A. Elizabeth Delany with Amy Hill Hearth is a work of non-fiction and therefore has a unique tone for a memoir. The Delanys, particularly Bessie, are well known for being outspoken, straightforward and unapologetic.
Although the book is a joint memoir, the sisters are able to present many facts objectively. The author adds in some historical time frame markers to assist the narrative, which is helpful to the reader. The sisters also relay their view of things as they were (e.g., Harlem during the Depression) and compare those things to the accounts written in history books.
