Dukkha Hungry Ghosts
December 28, 2015
As Mai and the crowd watch in frozen horror, the Lexus slowly rolls again until it's on its top; the front-end still nose down into the water. After a moment, only the rear back tires are still above the surface. Then they too slip beneath the bay.

Dukkha: Hungry Ghosts - A Sam Reeves Martial Arts Thriller
October 26, 2015
Prologue from the book: His legless torso swings back and forth between his arms, as he hand-walks along the dim but ornately lit cobblestone path that meanders about the lavish yard through tall bamboo, past large stone Asian lanterns, around half a dozen towering palm trees, and encircles a large pond.

Many kind reviewers for Dukkha: The Suffering, Dukkha: Reverb, and Dukkha: Unloaded have commented on the realistic violence, in particular the fight scenes. This is always nice to hear because I work hard to infuse the scenes with authenticity and truth.

Principles Common to Both Qin Na and Ground Fighting - September 30, 2013
A lever is the simplest of machines, which utilizes a rigid bar to rotate around a fixed pivot point called a fulcrum in order to exert force on an object (load). If the resistance or load exceeds the strength of the bar, the bar will break. Biomechanically speaking, the arm is a bar, and when the fulcrum is at or above the joint, breakage can easily occur.
