“Grinder 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.” — Mystery Scene
“Razor-edged prose and a sympathetic antihero lift Knowles’s no-holds-barred crime thriller … Readers who like their mean streets really mean will be thoroughly satisfied.” — Publishers Weekly starred review
“Knowles combines nonstop action with gritty violence to hold the reader’s attention. For fans of hard-boiled mysteries.” — Library Journal
“Picture perfect hardboiled writing. Knowles has a real grasp of the underbelly running under society and his characters all breath with authentic boozy cigarette breath. A great read and a great new voice.” — Crimespree
“A dead centre hit […] Read Mike Knowles’ first novel, Darwin’s Nightmare and now, Grinder. They are sharp, focused indications of a fine, new noir talent in our midst. Hang in there for the third.” — Hamilton Spectator
