“Gillis, himself a tae kwon do black belt, succeeds in debunking the sport’s mythology...When he writes about corruption and backroom dealings, his voice is compelling and the depth of his research astounding... A Killing Art is fascinating, fast-paced, and reads more like a spy novel than a history. Beyond that, it evokes a certain voyeuristic pleasure that comes with unearthing the sordid past of something seemingly harmless.”
