Juliana Perdomo is a writer and illustrator born in Bogotá, Columbia, surrounded by a huge loving family, friends, bright colors, music, weird fruits, sunshine, and lots of rain but also rainbows. She now lives there with her amazing son, Luca, her rocker partner Iván, and their crazy old dog, Menta. Juliana has a background as a psychologist and an art therapist, but her passion is children's literature.
