Fitz, the illegitimate son of a prince, must navigate the lethal political machinations of the Six Duchies while training as a secret royal assassin. Cast aside by his noble family, Fitz resides in the stables, isolated from the courtly life he technically belongs to. King Shrewd recognizes the boy's potential utility and initiates him into the clandestine arts of killing, forcing Fitz to balance his loyalty to the crown against his own survival. The narrative, presented through a reflective first-person perspective, chronicles his maturation amidst the looming threat of the Red-Ship Raiders and the internal instability of the royal house.
