Ekho is a mirror world to the earth. It has developed like her, but electricity doesn't exist; only magic reigns. On Ekho you'll recognize the usual continents, cultures, and cities. Paris, New York, London, Barcelona... they're similar yet very different. One travels on the backs of dragons or caterpillars. This series reinvents the contemporary world in a heroic fantasy version, magnificently illustrated by Alessandro Barbucci.
