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

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.
