Davide Cali is the author of more than 80 books and has been translated into more than 30 languages. He grew up in Italy where he began his career as a cartoonist and comic book writer. He is noted for his humour, his humanity and his keen sense of storytelling. He is also the artistic director of Book on a Tree, a literary agency.

Magali Clavelet is both an author and an illustrator, particularly for young people. She attended the Émile Cole art school in Lyon because she wanted to tell stories to children very early on. Since then, she has written and illustrated numerous children's books. She draws her inspiration from the heart of her family (her two children, her husband, her grandparents and Moon, her little cat...) and particularly enjoys drawing animals.
