In a world where battle-hardened warriors determine the fate of empires, war-ravaged nations seek out a new champion in the first book of a thrilling science fantasy trilogy: "that rare book that fully satisfies me as an action fan" (Fonda Lee, author of Jade City).​

In a world long ago ravaged by war, the nations have sworn an armistice never to use weapons of mass destruction again. Instead, highly-skilled warriors known as Grievar Knights represent their nations’ interests in brutal hand-to-hand combat.

Murray Pearson was once a famed Knight until he suffered a loss that crippled his homeland — but now he’s on the hunt to discover the next champion.

In underground and ruthless combat rings, an orphaned boy called Cego is making a name for himself. Murray believes Cego has what it takes to thrive in the world's most prestigious combat academy – but first, Cego must prove himself in the vicious arenas of the underworld. And survival isn’t guaranteed.  

"A book about warriors written by a master of the martial arts, and the mastery shows." – Evan Winter, author of The Rage of Dragons

"Bare-knuckle brilliance." – Jackson Ford, author of The Girl Who Could Move Sh*t with Her Mind
