For over five thousand years, there were always three binding rules for all Masters of Sinanju: 1) Payment is always in gold. No checks. 2) There is only one Master and one pupil. 3) No woman will ever be trained in Sinanju.
Sunny Joe Roam will throw the last two rules out the window in order to fulfill his tribe's oldest commitment. He will train both Stone Smith and his half-sister Freya Williams in the deadly art of Sinanju, ushering in a new era for the tribe. But will the lethal brother-sister duo be enough to help their new boss Benjamin Cole stop the Great Mexican Ninja Army from invading the southwestern United States?
