Julie Dachez is a writer, author of La Difference Invisible, Dans Ta Bulle! And L’autisme autrement in France. She is also a blogger, a YouTuber, a teacher, a researcher, a speaker, and an activist. She loves to play tennis and eat chocolate, not necessarily in that order. Julie writes at home, surrounded by her two dogs and her cat, Misti, who loves to take part in the writing process by lying on the keyboard.

Mademoiselle Caroline was born in Paris a few years ago. She is the author of around fifteen books, including Chute Libre, Carnets du Gouffre, a story about living with depression that has attracted the attention of the media and readers alike. La Différence Invisible was first published in France in 2016 and has since been a reference work on the autism spectrum, winning several awards and an Eisner Award nomination. Also, she skis a lot (with class and distinction), plays rugby (with panache and severity), walks a lot (with courage and tenacity), and looks after her three children of two different ages (it's possible!).
