"This dark tale of martial arts and ancient Codes in a fallen world will captivate readers who crave action."--Kirkus on The Combat Codes

"A brutal and relentless science fantasy martial arts extravaganza, set in a world where the fate of nations rests on the perfect counterpunch or rear naked choke. The Combat Codes is that rare book that fully satisfies me as an action fan." --Fonda Lee, author of Jade City on The Combat Codes

"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 on The Combat Codes

"Darwin's immensely satisfying conclusion to his Combat Codes trilogy pulls no punches ... The many plotlines hurtle toward an explosive finale. The martial arts scenes are as expertly devised as ever, and the riveting plot keeps the pages flying. This sends the series out on a high note."
