Meet the Tres Hermanas: Evelina Antonetty, Lillian López, and Elba Cabrera. They moved from Puerto Rico to New York City as children and grew up to become leaders in their Bronx community. Evelina, an activist for social causes, founded United Bronx Parents. Lillian became a librarian and administrator who fought for Spanish and bilingual books and Spanish-speaking library staff. Elba worked closely with Evelina and became an ambassador and advocate for the arts. Rhythmic verse by NoNieqa Ramos and vibrant illustrations by Nicole Medina provide a stirring look at three dynamic changemakers.
