What is in this box? This is the question that always comes up in front of a closed box. And the one that this book asks 31 times, offering 31 surprises in response. The reader only has to turn the page to go from the simple and graphic form of a closed box to the rich and narrative spectacle that the open box offers. The author and illustrator plays with the reader's curiosity, stimulates their appetite, desires and fears. Opening one of Cécile Boyer's boxes is like opening a small world, finding yourself in front of one or more possible stories. It's up to everyone to imagine their own.
