"Sounder" is a Black history novel written by William H. Armstrong and published in 1969. The book tells the story of an African American boy and his dog during the Great Depression in the American South. The boy's father is unjustly imprisoned for stealing food to feed his family, and the dog, Sounder, becomes a symbol of hope and loyalty throughout the family's struggles.

The novel explores themes of poverty, racism, and the resilience of the human spirit in the face of adversity. It also sheds light on the systemic injustices faced by Black Americans during this time period.

"Sounder" was well-received and won numerous awards, including the Newbery Medal in 1970. It has since become a classic of children's literature and is often used in schools to teach about important issues such as social justice and the African American experience.
