Grievar’s Blood

"Both protagonists are well realized, and Darwin masterfully balances vivid fight scenes with Cego and Solara’s character growth, all while neatly setting things up for the trilogy’s conclusion. It’s a knockout."

"This exciting and ambitious sequel to The Combat Codes expands the world and excels in character development ... the precarious ending will leave readers hungry for more."
 

"Ups the science fantasy stakes with increasing political tension, new POVs, and more complicated fight scenes that deftly reflect where the individual protagonists are in their personal journeys."
 

"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."

“With surprising depth and touching relationships, this debut packs a punch and sets up a fascinating foundation for the rest of the series. Great for fans of Will Wight.”

“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.” 

"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."

"If Mike Tyson wrote a scifi novel (and could write like he threw a right hook) it would read a little like The Combat Codes. Bare-knuckle brilliance."

"This book kicks ass--literally and literarily!" 

"A masterclass in action, set against a complex science fantasy world."

“Darwin skillfully deploys his expertise in this impressive debut and series launch ... [He's] adept at making blow-by-blow descriptions of bouts vivid and engaging. This is a perfect setup for the next volume and will especially appeal to fans of Pierce Brown’s Red Rising series."

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

"Brimming with equal parts brutality and heart, Darwin's novel presents a world where the fate of society rests in the hands of a chosen few. This fast-paced, action-packed novel is the first of a promising trilogy that will be a big hit with fans of martial art movies and MMA fights."

"Excellent fight sequences. [Darwin's] evocative and visceral descriptions not only deliver excitement and suspense in this underdog story, they build your understanding of the characters through how they fight — in a very similar way to Hong Kong movies."

"A story filled with action, intrigue, and a heart of gold ... one of the more unique science fiction books I’ve read in quite a while."

"An interesting mashup of sci-fi and fantasy that also reads like a love letter to martial arts."

"The Combat Codes brilliantly combines martial arts with the genres of sci-fi AND fantasy in an explosion of action and self discovery. Imagine if Rocky, Ender’s Game, and The Karate Kid were shoved into a mixer and shaken up. The Combat Codes would be close to what you’d find inside."

"The Combat Codes is combat as it was meant to be written: raw but elegant, a blend of the poet's wordsmithing and the martial art master's technical expertise. Better yet, it's a fun, heartfelt story about the underprivileged banding together to rise up. A fantastic reading experience."
 

"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!"

"The Combat Codes is a perfectly balanced cocktail of high-octane action, enthralling mystery, and genuine heart. Fans of Geralt and Ciri or the Hound and Arya will adore the dynamic between Murray and Cego, and fans of badass fight scenes will find plenty to love in these pages. A gritty, fully-realized world sets the stage for lovable (and hateable) characters, heart-pounding action, and twists that literally had my jaw dropping. Readers won't want to miss this one!"
 

"A deliciously brutal, back-alley brawl of a novel. Darwin writes his story with broken teeth and bloodied fists with an authenticity that speaks volumes about his experience as a fighter. If you like action, this is a must-read."

"A refreshingly unique take on magic academy epic fantasy. The action is brutal. Fast paced and compelling.”

"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."
 

"The Combat Codes was a fantastic read that takes you along the martial arts path of self-discovery. The storyline, training, fights and philosophy in the book made it highly enjoyable. Whether you are a martial artist, fan, or just an SFF reader, this book will be a lot of fun."
