Susan Hayes is in awe of children's limitless imagination and thirst for knowledge. She strives to learn from the children she knows and meets, and to enjoy the world through their fresh, curious eyes. Susan lives in the East Sussex countryside of the UK with her own children-Sylvie, Finley, and Sam; her partner Neil; and two gorgeous but slightly silly ducks, Dolly and Izzy. She has written dozens of children's books.

Susanna Rumiz is an illustrator based in Italy. She mainly works on children's books and likes to draw fun and adventurous stories with a pinch of mystery. In her free time, she grows jungles on her balcony and collects other people's shopping lists.
