"<cite>Grinder</cite> is made of tougher stuff, with a protagonist vaguely reminiscent of Lee Childs' unstoppable Jack Reacher... This tale of a man trying desperately to atone for his violent past is a stunner, and we can't help but root for this reformed killer as he loosens the ties that bind. Although there's much shoot-em-up action here, the story's real strength lies in the author's exploration of Wilson's troubled soul."
