Born in Paris in 1975, Geraldine Collet studied modern history and taught for 14 years, first in the Seine-Saint-Denis department, then in the Aisne, in the city of Saint-Quentin where she currently lives. She is now a full-time author and writes principally for young readers. She has published about 60 books for children, some of which have been translated into Chinese, Korean, English, Spanish, Arabic, Portuguese, Dutch, and Italian.

A multifaceted illustrator, Sebastien Chebret mixes it up with sundry paints and media: everything from gouache to acrylic and watercolor, from collages and repurposed paper gleaned here and there in secondhand shops to a growing use of digital tools.
