This powerful graphic novel tells the story of a giant wall separating two civilisations: one of blue people and one of yellow. Each side is forbidden to speak to the other, because they are sworn enemies. One day, a boy and a girl from opposite sides of the wall meet and decide to break down the boundaries that divide their peoples forever. The debut book from the hugely talented Jonathan Standing, this is a stunningly-illustrated story with an important message about overcoming prejudice and fear of the other.
