Jade is the lifeblood of the city of Janloon - a stone that enhances a warrior's natural strength and speed. Jade is mined, traded, stolen and killed for, controlled by the ruthless No Peak and Mountain families.

When a modern drug emerges that allows anyone - even foreigners - to wield jade, simmering tension between the two families erupts into open violence. The outcome of this clan war will determine the fate of all in the families, from their grandest patriarch to even the lowliest runner on the streets. Jade City is an epic tale of blood, family, honour, and of those who live and die by ancient laws in a changing world.
