Who is the narrator of Roll of Thunder, Hear My Cry?

The story of an African American family and the racial prejudices they face in Depression-era Mississippi, author Mildred D. Taylor's Roll of Thunder, Hear My Cry is narrated by the primary protagonist of the story--young Cassie Logan. The story is told through the mostly-innocent eyes of the nine year old girl, whose mother teaches at the local Negro school and whose mostly-absent father works in a different city. The family faces many struggles, financial and personal, during the course of the novel, and a defiant stand the family takes against buying from the local white-owned store puts them in further jeopardy. Cassie grows as the novel progresses, and she sees--and receives--first-hand some of the ill-treatment handed out to Negroes by some of the local white families.

Who is the novel Roll of Thunder, Hear My Cry dedicated to?

You can find the answer to your question on the dedication page of the novel Roll of Thunder, Hear My Cry. Author Mildred D. Taylor apparently based several of the story's characters on her own father, Wilbert Taylor. Mildred Taylor and her family lived in Jackson, Mississippi, before Wilbert moved them to Toledo, Ohio to escape the racial tensions in the Deep South. David, the father of the Logan family, is one of the characters based on Wilbert. Cassie's father is much-loved and greatly missed when forced to work apart from the family. Stacey, Cassie's older brother, is another. The author must have imagined that her father was like Stacey as a youth, serving as the head of the household while the father was absent, and learning life's lessons in the process. The dedication page reads

"To the memory of my beloved father who lived many adventures of the boy Stacey and who was in essence the man Davind."
