Book 1
For over five thousand years, there were always three binding rules for all Masters of 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?
