In 13th-Century Japan, a land of ghosts and demons, ancient spirits and shapeshifting animals, Ken’ishi is a warrior without master or family. Orphaned as an infant, he has only one link to his mysterious past—Silver Crane, the sword handed down from his father.

When Silver Crane is stolen, Ken’ishi must go on a quest to recover his very identity.

One man knows of Silver Crane’s significance, the underworld crime lord known as Green Tiger. A remnant of the shattered Taira clan, he dreams of the day when he can destroy the shogunate and bring his clan back to prominence. His intrigues stretch across the breadth of Japan, beyond the sea to China, where the Mongol emperor Khubilai Khan builds an invasion fleet and expands an empire.

With only a wooden sword for a weapon and a strange old man for a companion, Ken’ishi’s quest will take him deep into the shadows of a hidden world of flesh houses, Chinese smugglers, and Mongol spies.

To succeed and unleash the power of Silver Crane, he must face the darkness in his own soul.
