Jean-Francois Sénéchal was born among books. After studying anthropology, he returned to his first love, devoting himself to literature. He is a well-decorated author: the winner of the 2017 Joseph S. Stauffer Prize in Literature from the Canada Council for the Arts, a 2019 Prix jeunesse des libraires du Québec, and a 2021 Governor General's Award, for which he was also a finalist in 2019. Sénéchal was also named to the 2018 Honour List of the International Board on Books for Young People (IBBY). Chiaki Okada is an illustrator and author of children's books from Osaka. Her gentle, calming artwork was selected at the Bologna Children's Book Fair in 2010 and she has since illustrated books by authors from around the world. Her first picture book published in English, For All the Stars Across the Sky, (Walker Books) was released in 2019.
