After three years crossing seas, deserts, and the Silk Road, a young Marco Polo finds himself a prisoner of the great Kublai Khan.

As Kublai Khan battles his warmonger brother for rule over Mongolia, Marco learns that justice in Khan’s Imperial City is as swift as it is deadly.

Marco begins a dangerous relationship with the beautiful Blue Princess as tensions grow between Kublai and Xiangyang’s cunning chancellor Jia Sidao.

As war looms with the walled city of Xiangyang, Prince Jingim tests his diplomacy skills while Kublai questions Marco’s allegiance.

Marco searches for the mastermind behind a murderous plot, while Prince Jingim weighs the risks of retaliation.

On the eve of an auspicious ceremony, Marco searches for the culprit behind the assassination on Kublai Khan – even as a new one takes shape.
