Japan, 1866. As the Edo period collapses and foreign ships choke the harbours for the first time in over 200 years, young samurai Ito Katsuchiyo prepares to prove his worth in the coming bloodshed. But when his family is slaughtered by a rogue samurai warlord, his path of honour is replaced by a mission of vengeance.
The hunt leads him across the ocean to a brutal and unfamiliar land: The United States of America.
To survive, Katsuchiyo must forge unlikely alliances with an unruly gunslinger and a formidable native tracker.
But his enemy thrives in this chaos. And the deeper Katsuchiyo ventures into the frontier, the more he risks becoming the very monster he seeks to destroy.
Outnumbered and outgunned, will Katsuchiyo hold to the samurai code? Or trade honour for the only justice this savage land understands?
