It has been eleven years since Christian Winters brought the plans of his old Sensai, Michael Neal, to an abrupt and bloody halt. His daughter Haley, named after the woman he loved and lost, is training with both her father and mother, becoming a formidable fighter in her own right. Christian has settled into a life much less action filled than his early twenties were, having opened his own dojo, while Melissa Cervantes Winters, now his wife has become a lawyer. Everything is going well, with the small family living quietly. An attempt to rob Christian of the things he loves most will set off a series of events that pulls him back into his old life of blood and vengeance, in an effort to protect his family, his honor, and soon, the world.
