Born in Barcelona in 1970, Rocio Bonilla is a children's book author and illustrator. She began her career working in painting, muralism, photography, pedagogy, and advertising, but motherhood inspired her to leave the latter to create hand-painted murals for children's spaces. In 2011, she entered publishing as an illustrator and debuted as an author in 2014. To date, she has published around 50 books, sometimes collaborating with other authors, and her award-winning work has been translated into over 20 languages. She lives in Barcelona.
