Magical jade—mined, traded, stolen, and killed for—is the lifeblood of the island of Kekon. For centuries, honorable Green Bone warriors like the Kaul family have used it to enhance their abilities and defend the island from foreign invasion.

Now the war is over and a new generation of Kauls vies for control of Kekon’s bustling capital city. They care about nothing but protecting their own, cornering the jade market, and defending the districts under their protection. Ancient tradition has little place in this rapidly changing nation.

When a powerful new drug emerges that lets anyone—even foreigners—wield jade, the simmering tension between the Kauls and the rival Ayt family erupts into open violence. The outcome of this clan war will determine the fate of all Green Bones—from their grandest patriarch to the lowliest motorcycle runner on the streets—and of Kekon itself.
