The Kaul siblings battle rival clans for honor and jade in the epic conclusion of the World Fantasy Award-winning series, the Green Bone Saga. Jade, the mysterious and magical substance once exclusive to the Green Bone warriors of Kekon, is now coveted throughout the world. Everyone wants access to the supernatural abilities it provides, from traditional forces such as governments, mercenaries, and criminal kingpins, to modern players, including doctors, athletes, and movie studios. As the struggle over the control of jade grows ever larger and more deadly, the Kaul family, and the ancient ways of the Kekonese Green Bones, will never be the same. Battered by war and tragedy, the Kauls are plagued by resentments and old wounds as their adversaries are on the ascent and their country is riven by dangerous factions and foreign interference. The clan must discern allies from enemies, set aside bloody rivalries, and make terrible sacrifices… but even the unbreakable bonds of blood and loyalty may not be enough to ensure the survival of the Green Bone clans and the nation they are sworn to protect.

MAGIC DIVIDES. POWER CORRUPTS. FAMILY ENDURES. On the island of Kekon, the Kaul family is locked in a violent feud for control of the capital city and the supply of magical jade that endows trained Green Bone warriors with supernatural powers they alone have possessed for hundreds of years. Beyond Kekon’s borders, war is brewing. Powerful foreign governments and mercenary criminal kingpins alike turn their eyes on the island nation. Jade, Kekon’s most prized resource, could make them rich—or give them the edge they’d need to topple their rivals. Faced with threats on all sides, the Kaul family is forced to form new and dangerous alliances, confront enemies in the darkest streets and the tallest office towers, and put honor aside in order to do whatever it takes to ensure their own survival—and that of all the Green Bones of Kekon. Jade War is the second book of the Green Bone Saga, an epic trilogy about family, honor, and those who live and die by the ancient laws of blood and jade.

War seethed across the planet. Machines soared through the air, churned through the seas, crawled across the surface, pushing ever forward, carrying death. Earth was engaged in titanic struggle. Germany, Russia, France, China, Japan: the maps were changing day by day. The hostilities spread in ever-widening ripples of destruction: Britain, Italy, Africa...The fate of the world hung in the balance. Then the real enemy came. Out of the dark of night, out of the soft glow of dawn, out of the clear blue sky came an invasion force the likes of which Earth had never known - and worldwar was truly joined. The invaders were inhuman and they were unstoppable. Their technology was far beyond our reach, and their goal was simple. Fleetlord Atvar had arrived to claim Earth for the Empire. Never before had Earth's people been more divided. Never had the need for unity been greater. And grudgingly, inexpertly, humanity took up the challenge. In this epic novel of alternate history, Harry Turtledove takes us around the globe. We roll with German panzers; watch the coast of Britain with the RAF; and welcome alien-liberators to the Warsaw ghetto. In tiny planes we skim the vast Russian steppe, and we push the envelope of technology in secret labs at the University of Chicago. Turtledove's saga covers all the Earth, and beyond, as mankind - in all its folly and glory - faces the ultimate threat; and a turning point in history shows us a past that never was and a future that could yet come to be...
