"Narrator Donald Chang faces a particular challenge with this audiobook: how to produce the sound of testosterone.... Chang skillfully animates the pair at the heart of this stirring work, former champion Grievar Murray Pearson and his latest protégé, the talented but callow Cego. In addition, Chang ably handles a multitude of predominantly male characters, including Cego's fellow fighters and government officials who are hiding a big secret. Chang's distinct characters ensure smooth listening despite the complexity of the story. What results is an engaging production for fans of action and speculative fiction alike." (AudioFile)

“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)

"This book kicks ass—literally and literarily!"—Richard Swan, author of The Justice of Kings

"The Combat Codes is a well-paced sci-fi brimming with action, brutality, thoughtfulness and heart. From ruthless underworld to storm-harried, glistening academy, every fight is clear and visceral, and I couldn’t help but be ensnared by the mystery and tension woven throughout. I can’t wait for the next chapter in Cego’s journey!"—H.M. Long, author of Hall of Smoke
