Susanna Isern grew up among mountains in the Spanish Pyrenees. When she was little, her favorite hobby was to run around, discovering incredible insects and helping sick or endangered animals. It was then that animals started to whisper her stories, which she hurried to write in the notebook she always carried with her. She is the author of many children's books, most of them distributed internationally and translated into over a dozen languages. She has been awarded the Silver Medal in the Moonbeam Children's Book Awards 2013 in the USA.

Esther Gili was born in Madrid in 1981. She studied illustration at Art School No. 10 in Madrid. She worked for a decade illustrating textbooks and regularly collaborated with audiovisual production companies doing work for film and advertising.
In 2015 she published Encantadas, her first picture book, written by David Aceituno. And she hasn't stopped since! As well as picture books, Ester illustrates notebooks, bags and agendas made by Cuquiland and also has a collection of puzzles.
Her favorite technique is watercolor, so she uses it whenever she can. And a common element in her work is women with character, magic and kindness!
