This warm story emphasizes Ella's role in her success, thus avoiding the trap of the white-savior narrative. Many white artists have benefited from imitating black ones; this is the rare narrative to acknowledge that saturated with color, they capture the iconic looks of the two stars. A good volume to include in a larger conversation about friendship, allyship, and social justice. An inspiring story about 20th-century icons that will be unfamiliar to most young readers.
