A king who does not accept diversity exiles those inhabitants who are not like him and builds a wall to keep them away. Now the kingdom is divided in two, but nothing is the same anymore. The simple text and clever illustration, along with a pop-up wall that really rises as the story unfolds, "speak" to children in the most vivid way about how societies decline when discrimination and divisions prevail, and how they thrive when all people live in harmony and cooperate for the common good. With suggestions for discussion with children, as well as a fun "search and find" game on the pages! See the book presentation at the link below: https://www.youtube.com/watch?v=FTVD2z2-388&t=19s
