I have, and still do, implement business systems into corporates throughout the world, as an independent contractor. My academic background is in computer science. 
This work led me to see the seven deadly sins - pride, envy, gluttony, greed, lust, sloth, and wrath - up close, in the business world.
My stories are based on real events. More than one of these events gets massaged together to make up the story. The original names and locales had to be changed.  During this period I have been actively involved in martial arts.
This novel is the first of a series.
