'That rare book that fully satisfies me as an action fan' Fonda Lee, author of Jade City, on The Combat Codes

'Darwin writes violence with the rhythm and surprise of a well-executed sonnet, wedding the smooth grace of choreography with the unflinching brutality of fists breaking bone. The fights are mesmerizing, layered like fascia, twitching and flexing and propelling the story toward a conclusion that both satisfies and opens the door to the next volume' The New York Times on The Combat Codes

'The Combat Codes is a great read for any fan of realistic martial arts fiction. The integration of a compelling sci-fi / fantasy plot and true-to-life martial arts action make for a unique story that any student of warfare is sure to enjoy' Ryan Hall, UFC Fighter

'The Combat Codes by Alexander Darwin is a chimera blending Science Fiction and Fantasy to tell a vividly-realized tale both focused and sprawling. It's a book about warriors written by a master of the martial arts, and the mastery shows. In its pages, expect to explore power, politics, and brutal violence, but I repeat myself' Evan Winter, author of The Rage of Dragons
