Book excerpt: Broken down in the Sahara Desert, a pilot meets an extraordinary Little Prince, travelling across time and space to bring peace to his warring planet. Inua Ellams' magical retelling of the much loved story by Antoine de Saint-Exupéry turns the Little Prince into a descendant of an African race in a parallel galaxy. His journey as a galactic emigrant takes us through solar systems of odd planets with strange beings, addresses climate change and morality, and shows how even a little thing can make a big difference.
