Her children's book "No Dogs Allowed", published by Simon & Schuster Children's Publishing in 2004, is one of five books selected by the General Mills initiative "Spoonfuls of Stories". As part of that effort, Manzano is working with General Mills and its nonprofit partner, First Book, to encourage children to read and to help children across the United States gain access to books. The book has been adapted as a stage play. She is also the author of "The Revolution of Evelyn Serrano" (2014).
