An Italian book for children (yes!) about a boy with a very strong voice who travels to the kingdom ruled by a former pirate. The new king makes it a law for everyone to tell the exact opposite of truth. So if you want to buy some bread - you need to ask for a bottle of ink, if you have a cat, you talk about a dog.
Still, in the middle of that all, there's a lot of common sense involved.
A very nice way to take more relaxed approach to reality 8) What does it really mean when we talk about a cat?...
