Yvonne is Melody's older sister, and frequently nicknamed "Vonnie".
She attends Tuskegee University, her mother's alma mater, in Alabama and is in her second year at the start of Melody's books, placing her at about twenty years old. Like everyone in their family, Yvonne is a good singer. She is an activist for black rights, and participates in the March on Washington, Detroit Walk to Freedom (which members of her family participate in as well) and the Mississippi Summer Project. During the events of the first books, one of the things she does is fluff her hair out into an Afro, as a sign of black pride. She also works as a civil rights worked in the summer of 1964.
