Tenon spans ten countries, their territories are intertwined, and their intrigues are like a web. Berwick was born into a declining aristocracy and ran a humble warehouse in a border town. An accidental delivery of goods involved him in an undercurrent of espionage transactions among ten countries. Starting from a bag of grain mixed with sand, he must use the cunning of the market, the calculation of the businessman, and the aristocratic sense of smell that has never been lost in his bones to pry a way out among the forces of all parties. Will this road ultimately lead to the position of Duke of the country, or will it lead to an abyss of eternal destruction?
