Elizabeth Zunon, who grew up on the Ivory Coast in Africa and spent her teenage years in Guilderland, just published a book she wrote and illustrated, “Grandpa Cacao: A Tale of Chocolate From Farm to Family.” She is the little girl pictured on the cover of the book with the grandfather she knew through family stories but never met. Her book, dedicated to “all the Grandmas and Grandpas who broke their backs working in the fields so we wouldn’t have to,” is rooted in a particular family — hers — but has universal themes. In this week’s podcast, Zunon talks about her life as an artist and now, after years of illustrating others’ books, as an author.
