Joana Estrela was born in Penafield, Portugal in 1990. She started drawing family portraits at an early age, writing funny subtitles to go along with. Her methods haven’t changed a lot since—what motivates her to start a book is still the joy that comes with it. She is a graduate of the Faculdade de Belas Artes da Universidade do Porto and has won awards in her home country for both her picture books and her graphic novels.
