Celia is the daughter of a Mexican mother and a Cuban father. Originally from Miami, Florida, she now lives in Chicago with her family and works as a community college librarian. Inspired by punk and her love of writing, Celia has been making zines for a very long time. Her favorite zine supplies are glue sticks, animal clip art (to which she likes adding speech bubbles), and watercolor pencils. She owns two sets of worry dolls because you can never have too many. 

The First Rule of Punk, her debut book for young readers, is a 2018 Pure Belpré Award Honor Book, a winner of the 2018 Tomás Rivera Mexican American Children's Book Award, a Junior Library Guild selection, and was included in several best of the year lists including the Amelia Bloomer List, NPR's Best Books of 2017, the Chicago Public Library's Best of the Best Books, the New York Public Library's Best Books for Kids, School Library Journal's Best of 2017, The Horn Book Magazine's Fanfare, and ALSC's Notable Children's Books.
