'Bang!' says Roland, the hero of Nelly Stéphane and André François's book, and a drawn tiger turns into a real one. Roland is an ordinary schoolboy who discovers an amazing ability to make anything he can imagine come true with a magic spell. His boring day is filled with surreal scenes in which a doll comes to life, his friend Isabelle's fur coat turns into little animals, a zebra slips on a banana peel, and Roland even ends up in jail for a while.

The book tells the story of the power of imagination and the ability to change the world around us with a simple 'bang!'
