Mo is restless in his bed and can't sleep. A mysterious light, which seems to smile at him, invites him to venture into the forest, where all kinds of creatures live, some friendly and some frightening. Mo, a curious cat, will make friends with a wise old owl who encourages him to experience adventure beyond the confines of books (though caution is always advised). Mo will also meet a family of mice, a squirrel, and some reindeer who work, gather mushrooms, and enjoy themselves. With some, he will cook; with others, he will learn how to better prepare for the journey and how to greet politely, how to talk about what he likes, and also about what scares him. Together, they will solve some unexpected problems and forget their worries to enjoy the moment. Even though a fearsome bear with terrible breath is lurking nearby.

A story as delicate and exquisite as the pen-and-ink illustrations, in a beautiful hardcover edition for children aged 8 and up, and for the most discerning adults. The book received a special mention for Best First Work at the Bologna Children's Book Fair in 2024.
