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.
