Her debut novel,
Thereafter Johnnie, a semi-autobiographical portrayal of African-American life, was critically well received. Her critically acclaimed picture book
Nappy Hair, a call-and-response story based on her own experiences as a child, was the cause of massive controversy when a New York City
public school teacher was accused of racism after using it in the classroom.
Nappy Hair was originally planned as a chapter of an adult book, is influenced by the epic tradition and African praise tradition. Herron
edited the papers of
Angelina Weld Grimke for
Oxford University Press. Many of her writings, including her
multimedia novel in progress, "
Asenath and Our
Song of Songs", refer to the intersections between
Judaic and African cultures. Textual portions of "
Asenath and Our
Song of Songs" were published as separate novels in 2014, "Asenath and the Origin of Nappy Hair," and 2016, "PeacesongDC." Her children's book
Always an Olivia recounts the coming of Herron's Jewish ancestors from
Tripoli, Libya, to the
Georgia Sea Islands in the Americas. ==Teaching==
