The Wall tells the story of a king who notices how his kingdom, once populated by blue faces, is now inhabited by faces of all colours. So he decides to go back to the past and separate his people from the 'foreigners', expelling them and ordering the construction of a wall. Soon, however, he realises that all his wishes can only be achieved with the help of the different faces he had driven away. He therefore orders the wall to be torn down and succeeds in recreating a kingdom where people live in harmony, recognising the value of integration between people.

A successful book and an international bestseller that teaches children the importance and value of integration.
